"CTRL-C" and "try"
Hello everybody,
if I'm running a R-script on a command line R-session which uses the function "try" and I'd like
to interrupt the execution of my R-script pressing "CTRL-C" than R ignores the first "CTRL-C"
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

Hello everybody,
I have following string type and try to convert it to float:
> a<-"20020104.123456"

num 20020104
How can I get an float instead of an integer? How can I set the desired precision?
Thanks in advance

Rprof fails in combination with RMySQL
Dear R community,
I tried to optimized my R code by using Rprof. In my R code I'm using MySQL
database connections intensively. After a bunch of queries R fails with the
following error message:

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)?

What I want to do is something like the following example (Two or more plots with a
legend for each at one page):
data(volcano)
layout(matrix(1:2, 1, 2, byrow = TRUE))
for (i in 1:2) {

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

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,

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

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' .

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

Error while trying to manage file share
I checked my entire setup again and again. Now I can see the my share. The
most relevant change I did (afaik - ofcourse):

recommended in the docs)
- I removed the $ from the share section/defnition ([projects$] ->

- I changed browseable switch from 'no' to 'yes'

Controlling the length of line with abline(lm())
Hi
I just realized that when I use linear regression to draw a line through my
data points with something like the following:
abline(lm(y ~ x))
the length of the line is infinite, i.e., the line goes beyond the smallest
and the largest data values. This seems not very right to me (not to mention
it looks unaesthetic). I do not mean to imply that the straight-line
behavior of my system is
