Dear R users,
I have a very simple question and I've tried to search for the answer.
(But failed.)
there should be a function (func) that work like
> abc <- c(1,2,3,4)
> func(abc)
"abc"
I would like to know the name of that function. Thank you very much
for your help.

Thanks all. But I was looking for "KMedian" algorithm and not the "KMedoids"

Defining groups at a given height can be done with the cut function

Unfortunately, cut doesn't give you the option of specifying a number

Nope. You cannot just tack strings on the end of function calls. Try:

no.
Your best way is to use

Currently comments (#) are ignored by txtStart and friends due to the task
callback mechanism used. The txtComment function is available as a work around
to insert comments into the output/commands.
I tried running date() as below and everything worked as expected (the comments
were missing, b

Is this what you're looking for?

splitsdata = split(sdata,sdata$company)

Is there a way to plot this as julian day over years so that each species

Hi,
I have been trying to use the new .parallel argument with the most recent
version of plyr [1] to speed up some tasks. I can run the example in the NEWS
file [1], and it seems to be working correctly. However, R will only use a
single core when I try to apply this same approach with ddply().
Thanks for all the suggestions, guys. It looks like TIFF may be the easiest
solution, as I wouldn't have to worry about printing to a postscript printer
or converting to PDF (when using EPS). That way, I could send the Word file
as is to all coauthors (important for collaboration - i.e., track c

Hi all,
We know old.packages() can check for updates of add-on packages, but
is there a way to check updates of R itself? "go to R homepage" is a
way, of course, but I hope this can be done by R.
I'm not sure about the "reliable" place to check; here is a simple
example to check from one of the C

Hi:
Could you please devise a reproducible example that illustrates the problem?
As far as points (1) and (2) are concerned, if you lack row or column names,
they can always be defined and added to the object.

I am unsure if I can analyze data from the following experiment.
Fish were placed in a tank at (t=0)
Measurements of Carbon Dioxide were taken each day for 120 days (t=0,...120)
A few fish were then randomly pulled out of the tank at different days,
