how to trap any warnings from an R function
Within an user function, how are the warnings from an R function be trapped
(such that some proper actions can be taken)? 'last.warning' is returned
only at the top level. Pointers are appreciated.

Producing a table with mean values
Hi All,
I have a data set wit three size classes (pico, nano and micro) and 12
different sites (Seamounts). I want to produce a table with the mean and
standard deviation values for each site.

Interquartile Range
Well, instead of your functions try:
Mode <- function(x) {
tabx <- table(x)
tabx[which.max(tabx)]
}
and use R's IQR function instead of yours.
... so I still don't get why you want to return a character string
instead of a value for the IQR;
and the mode of a sample defined as above is generally a bad estimator
of the mode of the distribution....

...ti-modal distribution and the nuances of which kernel is used, etc., etc.
Food for thought.

Interquartile Range
Hi,
Here is what I am doing
notGroupedAll <- ddply(data
,~groupColumn
,summarise
,col1_mean=mean(col1)
,col2_mode=Mode(col2) #Function I wrote for getting the
mode shown below
,col3_Range=myIqr(col3)
)
groupedAll <- ddply(data
,~groupColumn
,summarise

If you show us, not just tell us about, a self-contained example
someone might show you a non-hacky way of getting the job done.
(I don't see an argument to plyr::ddply called 'transform'.)

regex scares me
Hi, apologies if this is too simple but I've been stuck on the following for
a while:
I have a vector of strings: filenames with a name before the extension and a
variety of possible extensions
I want to select only those files with:
1) a ".tab" extension
AND
2) the character sequence "lad" anywhere in the name of the file before the
extension.
Surely this
