Finding functions in uninstalled libraries
(Many thanks to David Barron & Jonathan Baron for pointing me to 'recode' in the 'car' package). I think I've been told this before, but how do I search for a function/keyword in libraries I don't yet have installed? (ie. on the CRAN site I tried the search engines with "recode" etc., but didn't pick up the car package this way) Stuart Dr Stuart Leask

Fw: write.table only writes the first 256 variables/columns
Thanks. I was "believing" an Excel import of the file - as you say, a re-import into R still has 333 columns. I shall look elsewhere for the cause of the mysterious truncation.

Oddity with internet access and R 11.0 with Sophos firewall and Windoze XP - solved
Just in case anyone else hits this. I just installed R 11.0 alongside R 10.1.0 (off my D: drive in D:\R\... but I think that's irrelevent) and all went well, I selected my nearest CRAN mirror (Bristol is the one I like) and getting the selection list seemed to take ages though it did come eventually. However, I then got an error message saying that R couldn't make contact on port 80. I

Quantreg - 'could not find function"rq"'
Hi all, I'm having some troubles with the Quantreg package. I am using R version 2.10.0, and have downloaded the most recent version of Quantreg (4.44) and SparseM (0.83 - required package). However, when I try to run an analysis (e.g. fit1<-rq(y~x, tau=0.5)) I get an error message saying that the function "rq" could not be found. I get the same message when I try to search

Installing an Archived Package
install.packages("/polycor_0.7-8.tar.gz", repos=NULL, type="source") The initial slash would be a problem - it means to find poglycor_0.7.8.tar.gz in the root directory. Remove the slash, find where the tar.gz file was put, and try using that location. Recall the destdir setting you used in download.packages or use file.exists() and dir() to help find it.

RE: z-scores for different factor levels
Hi Stuart, I often use this small function standardize <- function(x) ( x - mean(x, na.rm=T) ) / sqrt(var(x, na.rm=T)) to standardize variables. You should be able to use this to do what you want by splitting the data frame into sections based on the factor level, using standardize() to create a new variable in each section, then paste the data frame back together. Something like: #

R mailing lists: move from majordomo to [procmail+mailman]
We have locally collected good experience the last few weeks using procmail-spam filtering, inclduing spamassassin to the procmail filters. The last two spams that went past the majordomo filters (the "traditional ones I've been using) through to R-devel both were not delivered to me, be but caught by the filters. I have now collected a bit more of a week experience using the new scheme

Help with generating data from a 'not quite' Normal distriburtion
I would be very grateful for any help from members of this list for what might be a simple problem... We are trying to simulate the behaviour of a clinical measurement in a series of computer experiments. This is simple enough to do in R if we assume the measurements to be Gaussian, but their empirical distribution has a much higher peak at the mean and the distribution has much longer tails.

For loop indicies
I would like to run a for loop with an index going from 0 to 499 but the following seems to miss out the first value: C <- 499 for (i in 0:C) The alternative is: C <- 500 for (i in 1:C) { #Then every time I use i, I replace it with i-1 } Is this a good way to do it or is tere a better way?
