"are", the noun in your statement is "degrees", while the fragment "of

"degrees". Hope that helps... -- H

Re: [R] Post for R

Carrie,
I would suggest a few things before posting your code here:
- Put a dput(df)
- Format it properly, as it stands it won't compile, because you're missing
newlines/semicolons between, e.g. Z <- list()*; *G <- list(); for (i in
length(L1)){  Z=data.frame(L1[i])*;* G <- split(Z$submax,"0.02")*;*
 print(G)  }

Send a get request to

It also shows its webpage to be at http://www.omegahat.org/RSXML. On the
root of the site -- http://www.omegahat.org -- the installation command is
given as install.packages(packageName, repos = "http://www.omegahat.org/R";).
So perhaps, you should try install.packages("XML", repos = "
http://www.omegahat.org/R";) or install.packages("RSXML", repos = "
http://www.omegahat.org/R";) as one of those two should get you what you
want. Hope that helped... -- H

I'm not one to attack others in general, and have developed thick skin, so
a lot of what others find rude, I will ignore and get on with things. That
said, if someone does tell me that e.g. "Hasan is being offensive because
of $x, $y or $z", I'll apologise and get on with my life. Most of the time,
when people find me offensive, it's because I treat others how I wish to be
treated and the rhetoric just doesn't offend me. -- H

There's an explanation of the Kalman Filter available at
http://www.swarthmore.edu/NatSci/echeeve1/Ref/Kalman/ScalarKalman.html
-- I've summarised it below:
The kalman filter is used to reduce the noise in an indirectly
measured signal, s, approximated by the formula -- x[t] = a*x[t-1] +
b*u[t], to which a random amount of white noise is added, making the
equation x[t] = a*x[t-1]+b*u[t] + w[t]. The white noise varies with
time, hence it's a series. Each measure of x[t] brings you closer to
the actual signal. I hope this helps... -- H

Use xts whenever dealing with timeseries, to construct:
xts(data.in[,-1:2], order.by=as.POSIXct(paste(data.in[,1:2])))

Also, when you post help requests, use dput on your data set. I'm assuming
it's a data.frame, but I'd be able to actually test my code if there were
dput output in your question. -- H

Re: [R] gumbel distribution

Eliza,
See the gamlss package's Gumbel distribution[1], where you will find your
solution. OTOH, why does GAMLSS duplicate what's built-in to R? -- H

Re: [R] how to remove outliers

Marta,
To remove a row from your data frame, use:

value <- 14478.4
time <- time[-time[$TimeDiff] == value,]

I hope that helps... If not, do push back. -- H

You might consider setting the fetch size. I haven't used RJDBC in a few
months, but hopefully, the hints on
http://www.rforge.net/doc/packages/RJDBC/html/JDBCResult-methods.html point
you in the right direction? If not, email me off-list and I'll try to come

Indeed... the magic incantation seems to be:
results <- dbSendQuery(connection, sqlStatement)
partial.result.set <- fetch(results, number.to.fetch.in.one.go)
partial.result.set should be a data.frame with the number you've asked for.
It may take some tweaking to get it correct, but this is how to set the
fetch size in RJDBC. -- H

sql <- "select id, startdate, value from dists where profileid = ?"
data1 <- dbGetQuery(conn, sql, param) # Dies here, no matter what the query,

[R] RCurl HTTP Post ?

[Hasan Diwan]

According to [1] and [2], using RCurl to post a form with basic
authentication is done using the postForm method. I'm trying to post
generated interpolation data from R onto an HTTP form. The call I'm using is
page <- postForm('http://our.server.com/dbInt/new', opts =
curlOptions=(userpwd="test:test", verbose=T), profileid = "-1",
value="1.801", type="history"). The page instance shows the HTTP response
500 screen and I get a nullpointerexception in the server logs. The line it
points to is dealing with getting an integer out of "profileid". Help?
Many thanks in advance...

Yes that's exactly what I mean


Client-server interactions are hard to debug as the problems can be on
either
side or in the communication.  The error can be in your request, in
RCurl,
on the server side receiving the request or in the script processing the
request
on the server.


And I am (all too) aware of this. From the command line, it works fine,
using curl:
% curl -vvv -u "test:test" -d "profileid=-1" -d "value=1.801"
-d"type=history" http://our.server.com/dbInt/new

The equivalent code in RCurl would be:
postForm('http://our.server.com/dbInt/new',
curlOptions=(userpwd="test:test"), profileid = "-1", value="1.801",
type="history")

When I do run this code in R, I get:

Adding verbose=T to curlOptions results in an 'unexpected "," in
curlOptions', adding the verbose='true' to opts instead yields the same
result as above. If you should require further information, please ask. Many
thanks!

So it is imperative to try to get diagnostic information.

You used verbose = T  (TRUE).  What did that display?


Nothing


postForm() has a style parameter. It controls how the POST request is
submitted, either application/x-www-form-urlencoded or
multipart/form-data.
Your server script might be expecting the data in a different format
than is being sent. postForm() defaults to the www-form-urlencoded.

But we will need more information to help you if these are not the
cause of the problem.

[R] How do I make this faster?

[Hasan Diwan]

I was on vacation the last week and wrote some code to run a 500-day
correlation between the Nasdaq tracking stock (QQQ) and 191 currency pairs
for 500 days. The initial run took 9 hours(!) and I'd like to make it
faster. So, I'm including my code below, in hopes that somebody will be able
to figure out how to make it faster, either through parallelisation, or by
making changes. I've marked the places where Rprof showed me it was slowing
down:
currencyCorrelation <- function(lagtime = 1) {
  require(quantmod)

  dataTrack <- getSymbols(commandArgs(trailingOnly=T)[1], from='2009-11-21',
to='2011-04-03')
  stockData <- get(dataTrack)
  currencies <- row.names(oanda.currencies[grep(pattern='oz.', fixed=T, x
=as.vector(oanda.currencies$oanda.df.1.length.oanda.df...21.)) == F])
  correlations <- vector()
  values <- list()
  # optimise these loops using the apply family
  for (i in currencies) {
for (j in currencies) {
  if (i == j) next()
  fx <- getFX(paste(i, j, sep='/'), from='2009-11-20', to='2011-04-02')
  # Prepare data by getting rates for market days only
  fx <- get(fx)
  fx <- fx[which(index(fx) %in% index(QQQ$QQQ.Close))]
  correlation <- cor(fx, QQQ$QQQ.Close)
  correlations <- c(correlations, correlation)
  string <- paste(paste(i,j,sep='/'), correlation, sep=',')
  values <- c(values,paste(string,'\n', sep=''))
}
  }
  # TODO eliminate NA's
  values <- values[which(correlations[is.na(correlations) == F])]
  correlations <- correlations[is.na(correlations) == F]
  values <- values[order(correlations, decreasing=T)]
  write.table(values, file=commandArgs(trailingOnly=T)[2], sep='',
qmethod=NULL, quote = F, row.names=F, col.names=F)
  rm('currencies', 'correlations', 'values', 'fx', 'string')
  return()
}
lagtime <- as.integer(commandArgs(trailingOnly=T)[3])

require(quantmod)

I can open the resulting file in Excel without problems. Depending on

1. Do give a subject line -- a blank one is commonly used by a virus.
2. In R/S+/most functional languages, you do not want to write a "for
loop". Use apply (and friends) instead.

For example, if you wanted to know the stocks share of the total market as
a fraction, you'd use something like:
sapply(myData[,c(2:4)], function(x) {
return(as.numeric(x)/as.numeric(myData[,4])) })

Hope that helps.. -- H

Several options...
1. write.csv import into Excel and save to an XLSX
2. there is an xlsx package on cran that also, theoretically works. I say,
theoretically, because I have no use for Excel on my systems.

[R] Weird Excel Time Format

"2007-11-20 13:42:20". Applying as.Date() with the default format
doesn't do it. Any ideas as to what format this is? Many thanks! -- H

I did, it seems there is either (a) a problem with my code, or (b) a

It was contrived, so probably was wrong and I should have made that explicit.

I'm using the xlsx package to access this file. It is an XLS file. I
think I got it sorted though. The column that has the problem has
NA's, whereas the column that does not is complete.

Will look into doing so...

Mr Sankaran,
It may be your character set that's wrong or check your MySQL
configuration.

[R] Optimising timeboxing in xts

[Hasan Diwan]

I don't know if timeboxing is the correct term to use to accomplish
what I'm attempting, so allow me to explain. I have a set n of tagged
observations in time series t. What I'm interested in is taking i
seconds before and after every n. My code is below:
# observations.xts is an xts time series and arg is the number of
seconds to for the timebox
timeboxes <- sapply(c(1:as.numeric(last(index(observations.xts))-arg)),
function(x) { return(observations.xts[index(x) - arg, index(x)+arg])},
simplify=TRUE)
What I'd like to see in timeboxes is observations.xts elements with
timestamps within the range of abs(arg).

Seeing as there is no source code, I'm taking a stab in the dark, but
the below gives me a pie chart:
to <- as.POSIXlt('23:59:59', format='%H:%M:%S', origin=Sys.Date())
from <- as.POSIXlt('00:00:00', format='%H:%M:%S', origin=Sys.Date())
range <- seq(from, to, by = .5)
dallas <- data.frame(offense_hour = range, stuff = rnorm(c(1:length(range
p <- ggplot(dallas, aes(x = offense_hour) + geom_bar() + coord_polar)
