OO programming & S3/S4 paradigm - General question
Hi,
Being relatively new to OO programming and not so old on R, I noticed the possibility to do OO programming in R.
But it seems there is two "paradigms" S3 that seems the old one but is the one used in the R.oo package and S4 which seems more recent
As a starting point, which one is best to use? Is R.oo useful? what are the main difference between the two?
Any feedback

for loop Vs apply function Vs foreach (REvolution enhancement)
Dear all,
I know this topic has already been covered in other posts (at least the for loop Vs apply family of function), but I am looking for fresh / up-to-date opinion and feedback on those 3 methods to run unavoidable loops in R.

>> Seems apply is (was?) supposed to be faster than

Saving plot into file without showing it
Hi List,
My apologies in advance if question is simplistic, I am quite new to R graphics capabilities and I could not find anything in past threads...
I use R 2.8.1 under Mac OS X, but I would preferrably have a cross platform answer as I use also R under Windows
I produce plots using R & save them in a file
e.g. below:
y <- rnorm(1000)
x <- rnorm(1000)
plot(x,y)

t.test in a loop
Hi All,
I've been having a little trouble with creating a loop that will run a a
series of t.tests for inspection,
Below is the code i've tried, and some checks i've looked at.
I've used the get(paste()) idea as i was told previously that the use of the
eval should try and be avoided.
I've run a single syntax to check that my systax is correct and works
without any problems

Relative paths in R?
Dear list,
I use the R CMD BATCH to run a file of R commands (from php for info)
This file of R commands contains a line to source a configuration file "source('path/conf.R')"
In this configuration file I define some variables, e.g. the path of some file (uploaded before this R CMD using php) "PathUpload <- 'path/uploads'"

I could not find a mailing list of R under ubuntu, so I give it a try here...any direction/suggestion welcome
