Dear all,
for my diploma thesis I have to import huge XML-Files into R for
statistical processing - huge means a size about 33 MB.
I'm using the XML-Package version 1.9
As far as reading the complete file into R via xmlTreeParse doesn't
work or is too slow, I'm trying to use xmlEventParse bu

Hi All,
I've been successfully using the with function for analyses and the
transform function for multiple transformations. Then I thought, why not
use "with" for both? I ran into problems & couldn't figure them out from

When you constructed the data.frame, all strings were converted to
factors. If you didn't want that, it would have been possible to
specify it:
df<-data.frame(a=a,b=b,c=c,stringsAsFactors=F)
Then everything would work as
I try to use ls.str to return a character object ("at") in an attached data
frame, "folder", like so:
ls.str(pos="folder", pattern="at", envir=as.environment("folder"))
R accepts the command but returns nothing. Does this make sense to anyone?
Actually, what I want is the position (row and colu
Hi R users,
"genoud" function of "rgenoud" package will optimize my function. If
opt = genoud(fn,2,max=TRUE,starting.value=c(1,10),)
opt$value will give the optimized value of the function, "fn". My
problem is from the same opt, can I get the value of the function at the

I am a very happy user of emacs, ess, Sweave. My complaint is about
aquamacs (under OS X) and might not apply to other emacs variants.
There is one piece of visual detail that I think is a problem. When
the cursor moves from a line that's latex to a line that's R, ess

Nope. The two are equivalent for the Spearman test,
Hi R users,
I have a problem in downloading Yahoo Finance data from R. I have tried
an example given in R, to download. The error is given below:
>library(fCalendar)
> yahooImport("s=IBM&a=11&b=1&c=1999&d=0&q=31&f=2000&z=IBM&x=.csv ",
file = "D:\\ Downlaod",source = "http://ichart.yahoo
Thanks for the clarification. I should have recognized the difference
between "warning" and "error."
But if I may take this a step further, shouldn't it then be exact=TRUE
instead of exact=NULL?
Thanks,
Andrew

I run R 2.5.1 on a Mac, and use JGR as the front-end. When I
performed an update.packages(), I believe it unpdated a component of
JGR. I then quit and tried to relaunch JGR. It wouldn't launch.
Instead it opened a panel that says: "Cannot find iplot Java classes.

Perhaps you want this?

Dear all R users,
Please ignore it if you feel it is 'off-topic'. Can anyone here suggest me
some good books on Application of Neural network on time series forecasting?
