I installed the RPostgreSQL package in R with all the dependencies
also.

I know that my question is like a very newbie question, but at the moment

statistical overview of various datasets, the summary() and numSummary()
functions are fully sufficient. My question is, how can I export results

Hello,
I need to put 2 or more different time series to one plot for comparison
each other. The problem is that the time series are irregular, moreover
the time lenghts and periods are not the same. Is there a way to manage
it in R?
Many thanks for any hint and advice in advance

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 ...

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 = "***")

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_da

when I tried to apply xlim, ylim, zlim functions to the
plot3d/decorate3d, inspite all the help documentation I got this
errormessage:
ERROR: could not find function "xlim"
Is it a bug or possibly my fault?

If anybody is interested (maybe not :-)): finally I found a workaround:

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 :-)
