Hi, I have the following function: TEST <- cbind(Pox0t30.stone.1990.2000, sqrt(apply(Pox0t30.stone.1990.2000[,2:11], 1, var))) In rhe resulting Object TEST the added column is titled: sqrt(apply(Pox0t30.stone.1990.2000[,2:11], 1, var) I would like to change it to a sensible variable name like PoxMean. How can I incorporate this into the above function? Ulrich --

Dear list, I would like to make a comment how to solve the X11 font problem under SuSE Linux (9.0) when you get the message: "X11 font at size 16 could not be loaded". After having modified /etc/X11/XF86config as root (see below) you have to run 'SuSEconfig' as root as well else nothing might be changed in the X-Server. After that no further messages should appear. HTH,

Dear all ?Hmisc::rcorr states that it takes as main argument "a numeric matrix". But is it normal that it fails in such an ugly way on a data frame? (See below.) If the function didn't attempt any conversion to a matrix, I would have expected it to state that in the error message that it didn't accept 'data.frame' objects in its input. Also, I vaguely remember having used

Hi all, Sorry about posting a really novice question. I was able to run rcorr after converting the list to a matrix by your help. I'm though wondering if there is any way to find out an exact p value as the output only gave me 0 for P value as shown below. I've added options(digits=10), which doesn't seem to help at all. Any help would be appreciated. P D Prime T

Dear list, I get random terminations of R-2.6.2 when using RODBC-1.2_3 and a remote PostgreSQL-8.2.6 database, unixodbc-2.2.11-16, odbc-postgresql-1:08.01.0200-2.1 on Ubuntu Linux 7.10.
