how to apply several math/logic operations on columns/rows of a matrix
...ks (maybe there is and I just don't know but I checked
several R books and could not find a command to do this).
It would be great to have a function in which it is possible to define a
sequence of commands that can be applied column/row-wise.
Thanks for a hint,
Marc

r bug (?) display of data
Hi R Fans,
I stumbled across a strange (I think) bug in R 2.9.1. I have read in a
data file with 5934 rows and 9 columns with the commands:
daten = data.frame(read.table("C:/fussball.dat",header=TRUE))
Then I needed a subset of the data file:
newd = daten[daten[,1]!=daten[,2],]
--> two values do not meet the logical specification and are dropped.
The strange thing about it:

R performance
Dear R Fans,
I was recently asking myself how quick R is in code execution. I have
been running simulations lately that need quite a time for execution and
I was wondering if it is reasonable at all to do more computational
extensive projects with R. Of course, it is possible to compare
execution time for the same code written in several languages but maybe
someone has some experience on the
