Hello,
I'm actually struggling with the similar problem. I applied Your script
into mine like this:
-
library(Rdbi)
library(RdbiPgSQL)
conn <- dbConnect(PgSQL(), host="localhost", dbname="BVS",
user="postgres", password = "**")
query_duj_kal <- dbSendQuery(conn, "select zdroj as well, cas as date,
fe2, fe3, mn, nh4, no2, no3, o2, teplota as temperature from analystats
where zdroj like 'Dunaj Kalinkovo' order by date")
watchem_duj_kal <- dbGetResult(query_duj_kal)
date <- (watchem_duj_kal$date)
date_p <- strptime(date, "%m-%d-%Y")
no3 <- (watchem_duj_kal$no3)
nh4 <- (watchem_duj_kal$nh4)
par(mfrow=c(3,1), ylog = TRUE, yaxp = c(0.01, 100, 3))
maxy <- 100
miny <- 0.005
plot(date_p, no3,log = "y", type = "l", ylim = c(miny, maxy), col =
"darkred", main = "Dunaj Kalinkovo", xlab = "time", ylab = "log(NO3-,NH4
+)", xaxt="n")
axis.Date(1, at=seq(as.Date("1972-01-01"),max(as.Date(date_p))),
"years"), labels = FALSE, tcl = -0.2)
axis.Date(1, at=seq(as.Date("1970-01-01"),max(as.Date(date_p))),
"5 years"), labels = TRUE, las=3, tcl = -0.2)
-
Everything goes well, except that I cannot get no tickles nor labels at
the moment and I cannot find what I did wrong.
Many thanks for any advice
Tomas

Many thanks,
the solution is simple and elegant, as usual ;). R is a great tool, the
best I know, unfortunately I need more time to practice ...

[R] yaxp problem for more irregular time series in one plot
Good day,
I'm trying to get more time series in one plot. As there are bigger
differences in values of variables I need logaritmic y axis.
The code I use is the following:
nvz_3_data <- read.csv('/home/tomas/R_outputs/nvz_3.csv')
date <- (nvz_3_data$date)
NO3 <- (nvz_3_data$NO3)
NH4 <- (nvz_3_data$NH4)
date_p <- as.POSIXct(date, "CET")
par(mfrow=c(2,1), ylog = TRUE, yaxp = c(0.01, 100, 3))
plot(date_p, NO3, log = "y", type = "l", col = "darkred", main = "NVZ-1",
xlab = "time", ylab = "NO3-" )
lines(date_p, NH4, col = "darkblue", lty = "dotted")
plot(date_p, NH4, log = "y", type = "l", col = "darkblue", main = "NVZ-1",
xlab = "time", ylab = "NH4+" )
So, as I anderstood, extreme (max and min) values on the y axis are
conntrolled byt the yaxp, but it is ignored on the plot, and the NH4
values are out of the plot (see the attached picture). Do somebody know
what I am doing wrong?
Many thanks in advance
Tomas

[R] basic statistics to csv
I know that my question is like a very newbie question, but at the moment
I stacked with it and I need a quick solution. I need to make an overall
statistical overview of various datasets, the summary() and numSummary()
functions are fully sufficient. My question is, how can I export results
to a spreadsheet-like file, as a .csv. For the summary() with an "x"
dataset I can use this way:
su <- summary(x)
write.csv(su, file = "summary.csv")
The problem with this is that the csv file is rather chaotic.
but when I apply the same for the numSummary(x) output like:
nsu <- numSummary(x[,c("a", "b", "c")], statistics=c("mean", "sd",
"quantiles"), quantiles=c(0,.25,.5,.75,1))
write.csv(nsu, file = "numsummary.csv")
I get the "ERROR: cannot coerce class "numSummary" into a data.frame"
message.
Is there a more convenient way to get a spreadsheet-like output for the
basic statistics?
Many thanks for any help

Very nice text, indeed. As my 2 cents I strongly recommend to use for
graphs the .png format, .jpg is primarily designed for photographs.
Have a nice time

Re: [R] saving plot both as jpg and pdf
Just an advice: I recommend use the png device instead of jpeg for
plotting purposes, it gives better results for graphs. Jpeg is better
for photos. Off course IMHO :-)
I wish a nice day

[R] format (?) problems with data imported from postgres
Good day, I read some data from a PostgreSQL database by a following script: library(Rdbi) library(RdbiPgSQL) # conn becomes an object which contains the DB connection: conn <- dbConnect(PgSQL(), host="localhost", dbname="BVS", user="postgres", password = "***") query_duj_kal <- dbSendQuery(conn, "select zdroj as well, cas as date, fe2, fe3, mn, nh4, no2, no3, o2, teplota as temperature from analystats where zdroj like 'Dunaj Kalinkovo'") watchem_duj_kal <- dbGetResult(query_duj_kal) My intention with the data is to create a time series by a following script: date <- (watchem_duj_kal$date) NO3 <- (watchem_duj_kal$no3) NH4 <- (watchem_duj_kal$nh4) maxy<-max(NO3,NH4) miny<-min(NO3[NO3>0],NH4[NH4>0]) date_p <- as.POSIXct(date, "CET") par(mfrow=c(2,1), ylog = TRUE, yaxp = c(0.01, 100, 3)) plot(date_p, NO3,log = "y", type = "l", col = "darkred", main = "NVZ-1", xlab = "time", ylab = "NO3-" ) lines(date_p, NH4, col = "darkblue", lty = "dotted") plot(date_p, NH4, log = "y", type = "l", col = "darkblue", main = "NVZ-1", xlab = "time", ylab = "NH4+" ) The first problems comes with the definition maxy and miny (following a previous advice od Christian Poersching through this mailing list) what worked pretty well with data imported from a csv file by a read.table() function, but in this case I got NA output The next problem comes with the unambiguous format od the "date" field, which is in the database defined as -MM-DD, but in the resulting "watchem_duj_kal" dataset is strangely converted to DD-MM-, what is unambiguous for the as.POSIXct() function expecting -MM-DD. A function converting the format of the date should help, but I could not find untill now. I appreciate every advice/suggestion/help.

[R] RPostgreSQL, RS-DBI error
Hello all,
I have a problem with the connection to a Postgresql database in R.
At first, some system information:
Fedora 2.0,
R 3.1.0 compiled from source,
Postgresql 9.2
I installed the RPostgreSQL package in R with all the dependencies
also.
When I'm trying to connect to the database using the following commands:
library(DBI)
library(RPostgreSQL)
drv <- dbDriver("PostgreSQL")
con <- dbConnect(drv,
dbname="Litava",host="localhost",port=1234,user="postgres",password="")
I'm getting an error message:
ERROR:
RS-DBI driver
with no other error specification. Do have somebody an idea could be
wrong with this?
Thank You in advance for any advice
Tomas

[R] Change legend in the 'hydrogeo' package
At first sorry for the possibly dumb question of a newbie.
I am using the hydrogeo package to visualize approx. 300 data within the
Piper-Hill diagrams. The package is using a dataframe with 6 columns,
first of them is containing the row.names, next four with the data
itself. The last column contains "WaterTypes" dividing data to several
categories. The diagram is created by the piper function, assigning
different symbols following the row.names (I don't need id, however I
can assign one symbol for the whole dataset using pch ) and assigmning
colours following WaterTypes. Untill now it's working very well, what I
need however is to change the legend, as it is showing all the 300 rows,
even I assigned only one symbol. For me it is more appropriate to show
the categories from the "WaterTypes" columns assigned to the colours.
Could somebody give me a hint how to change the code to give me an
appropriate result? The answer is probably in the help assigned to the
"legend" of the graphics package, but it's quite unclear to me.
Many thanks in advance
Tomas
The piece of code from the hydrogeo package creating the legend is here:
ylegend <- X
plotlegend <- function(dd, X, ...) {
xid <- c(X + p)
yid <- c(ylegend - (X/30) * 1:nrow(dd))
text(xid, yid, labels = row.names(dd), vfont = c("serif",
"plain"), cex = 0.7)
if (is.character(dd$pch)) {
text(xid - (X/15), yid, labels = c(1:nrow(dd)), vfont =
c("serif",
"plain"), cex = 0.7)
}
else {
points(rep(xid - (X/15), length(yid)), yid, pch = dd$pch,
col = dd$col)
}
return(min(yid))
}

[R] 3D scatter, groups, RdbiPgSQL...
hello, I wish to create some 3d scatter diagrams visualising different grouped data set by a given field in the database. I tried the scatterplot3d package, as well as the plot3d and scatter3d functions (both within the rgl resp. Rcmdr package). My first question is, whether is it possibe to group data in the scatterplot3d and plot3d, because I did not succeed to use the groups = ... function.

hello,
I wish to create some 3d scatter diagrams visualising different
grouped data set by a given field in the database. I tried the
scatterplot3d package, as well as the plot3d and scatter3d functions
(both within the rgl resp. Rcmdr package). My first question is,
whether is it possibe to group data in the scatterplot3d and plot3d,
because I did not succeed to use the groups = ... function.
There is no groups argument to plot3d, but you can set characteristics
of each point separately. So if you can calculate a colour for each
point yourself, you can do something like
plot3d(br_scatter[,c("cl", "br", "hco3")], col=colour)
I see, but it is something new for me. So, if I understood You well, You
advice to prepare another column containing colour codes (colour names?)
for each point?
If you want different sizes for each point, you have to plot each
group separately; the size= attribute can't be a vector. You could
also use text3d to plot character labels, e.g.
plot3d(br_scatter[,c("cl", "br", "hco3")], type="n")
text3d(br_scatter[,c("cl", "br", "hco3")], text=br_scatter$stratigraphy)
In some cases it should be nice, but I have hundreds of points, no space
left for labels, but I can use it later.

The scatter3d behaves a bit wierdly with the groups function: it
works well with data imported from a CSV file, but when I tried to
apply it to a data imported from a PostgreSQL database (using the
Rdbi and RdbiPgSQL packages) it gives me this error message:
ERROR:
groups variable must be a factor.
To be more clear here is a command I used with the scatter3d (exactly
the same for the both datasets):
scatter3d(br_scatter$cl, br_scatter$br, br_scatter$hco3,
fit="linear", residuals=TRUE, bg="white", axis.scales=TRUE,
grid=TRUE, ellipsoid=FALSE, xlab="cl", ylab="br", zlab="hco3", groups
= br_scatter$stratigraphy)
the dataset I used is here (the same is the data imported from the
CSV file and from a PostgreSQL table) looks like this (a part of it):

So why the exactly same "stratigraphy" field is a factor in the
dataset imported from a CSV file and why is not a factor in the
dataset imported from a PostgreSQL table
Many thanks in advance

Re: [R] plot3d - could not find function "xlim"
Hello, thank You for Your reply. You are absolutely right, I am a bit tired, forgot to attach the code. I am very sorry about that, as well as I did not recognize that the error message came as a consequence of misstyping the code, my fault again (a real guru maybe recognize this as a misstype error as the error message is mentioning xlim as a function and not an **argument*, *I am apparently far to be a guru ... yet* *;-)).
