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?

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.

Hi, let's say I have data

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,

Nope. The two are equivalent for the Spearman test, but not
I am a very happy user of emacs, ess, Sweave. My complaint is about

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
Hi R users,
genoud function of rgenoud package will optimize my function. If

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 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 column #'s)

I've been successfully using the with function for analyses and the
