grid lines outside plot region in version R1.4.1
Hello everybody,
if I'm using par(xpd=NA) gridlines will plotted outside the plotting region. This is "new" (and, in my
opinion, unaesthetic) in version 1.4 - compared to version 1.3. Is this a bug or a feature?
Example:
------------------

key stroke and after I pressed "CTRL-C" second time R by itself is interrupted and I fall back
to the (UNIX-) command prompt. Without using

line length limitation in ROracle
Hello everybody,
I found that queries (send by "dbExecStatement" ) with more than 4000 characters
length produces an error in ROracle (ver 0.3-3). Maybe there is a limitation of 4kB....
Is this a bug? If yes, is this problem solved in the latest version of ROracle (ver 0.5-0)?

How to use multiple versions of a R library?
Hello everybody,
is there a possibility to install and use multiple versions of a R library
at the same time?
A few words regarding the background of this question:
If I change functions of an already developed package, I have to
verify complex functions in a lot of R applications. So it would be useful
to use different versions of a function/library and switch to the newer
function/library

getting source file name
Hello everybody,
is there a way to get the file name of the source file from which I read and
execute my R code?
In other words: If I'm executing "source('myRfile.r')" I'd like to have a statement
inside myRfile.r like "src.file<-$0" (in unix csh style) which assigns th variable
src.file to 'myRfile.r' .
Thanks in advance!

rbind wastes memory
Hello everybody,
if I try to (r)bind a number of large dataframes I run out of memory because R
wastes memory and seems to "forget" to release memory.
For example I have 10 files. Each file contains a large dataframe "ds" (3500 cols
by 800 rows) which needs ~20 MB RAM if it is loaded as the only object.
Now I try to bind all data frames to a large one and need more than

Subtitle?
Hi,
Is it possible to add a subtitle that appears directly below the main
title?
I tried the "sub" parameter, but it adds sub-title to the bottom of the
plot.
Cheers,

offset labeling boxplots
Hello everybody,
often I plot boxplots with different number of boxes (up to 200 boxes).
I'd like to give every box a readable label on the x-axis. Therefore, I
decrease the fontsize of the names and plot them vertical.
But if you zoom into the plot (pdf) you will find an offset between the
tickmark and the label - the label is shifted to the right.
If you vary the box.count in the
