Tinn-R editor question: saving syntax colour options.
Hi,
after reading about it in the forum, I tried the Tinn-R editor (in
WinXP) running R 2.5.0... nice one!
However, I am trying to change the syntax-colouring from the default
to my own preferences... and I can do that, but my options don't
appear to be saved and get lost when I close Tinn-R. I've searched
help menus, and google... and I can't find how to make sure my

how to display a string containing greek chrs and variables
I'm trying something that I thought would be pretty simple, but it's
proving quite frustrating...
I want to display, for instance, the correlation coefficient "rho" in a graph.
I can do something like:
text(x, y, paste("rho =", cor))
where cor would be my previously calculated correlation coefficient,
and x and y the coordinates.
Obviously that displays

selecting a group of points from a scatterplot?
Hi everyone,
is there a way/package in R that would allow me to select a group of
points from a scatterplot by drawing a circle around them or some such?
I can use 'identify' to pick individual points, but that gets tedious
if one has more than 10-20 spots.
I can easily select spots within a rectangle defined by picking points
using identify... but a simple rectangle sometimes will

Calling R from a Perl script: much slower?
Hello list,
I use R for microarray analysis.
One procedure I use takes a large matrix, and loops through it looking
for specific rows, does an operation with them, and outputs a result
(single row) as a row of another matrix. The loop goes on about 25000
times.
When I run the loop directly from the R console itself, it takes about
3 minutes in my computer. I'm ok with that.
Now,

Opening a web browser from R?
Hi,
I was wondering if there's a way in R to open a web browser (such as
Internet Explorer, or Firefox or whatever).
I'm doing some analyses that have associated urls, and it would be
nice to have the ability to directly open the relevant page from
within R.
I was looking at the help for 'url' and I can see I can probably
access the information I need and display it in my

read.table & readLines behaviour?
Hi,
I have been using 'read.table' regularly to read tab-delimited text
files with data. No problem, until now.
Now I have a file that appeared to have read fine, and the data inside
looks correct (structure etc), except I only had 15000+ rows out of
the expected 24000. Using 'readLines' instead, and breaking up the
data by tabs, gives me the expected result.

3D-scatterplots - high quality rendering?
I have just started using the package 'rgl' to explore my data as a 3D
scatterplot.
It's a great tool. But I would like to be able to save some graph
views and it appears the only format available is 'png' and it doesn't
look that nice. It is excellent to work with on screen and
explore/play, but when it comes to producing a good quality graphic

Sending PATH using SendEnv
Hi
I thought this was something that might concern the developers so I thought I'd post here. Apologies in advance if that's not the case.
I'm setting up a CentOS cluster with OpenSSH_4.3p2 which uses ssh to launch processes on the remote nodes. I'm trying to use the SendEnv/AcceptEnv functionality to send the PATH environment variable from the headnode when users are launching

negative number to positive number
Hello all,
I know this is a pretty easy question but I can't find it in S poetry or
R help.
How can I make a negative number positive. Such as
-5 to be +5
I tried +(-5), but that didn't work.
So no, I don't mean taking a -5^2 just to get a positive number.
This is in a function so it's not just -5 it's x. :)
Thanks,

Left/right hand side characters
Hello all
Is there a way reducing the number of characters in a list so that just
the left n numbers of characters is given?
For example, If I have a list, listnames, which consists of 4 strings of
6 characters;
>listnames

Is there a way to reduce this so only the 5 characters on the lefthand
side are

"strange" behaviour: recognition of decimal numbers by 'which'
It is a strange behaviour in that I did not expect it... but I am sure
there is a simple explanation for it and it'll have to do with the way
numbers are stored in R, but it's caught me by surprise and I don't
find it obvious.
Here's a simplified example reproducing the behaviour I encountered:
I create an empty vector, and I fill it with a sequence of numbers: 0,

Legend outside plotting area
Hi,
I have been trying many of the suggested options
to place a legend outside plotting area, including
something like this:
par(xpd=T,
oma=par()$oma+c(4.5,0,1.5,0),mar=par()$mar+c(1,0,1,0)
But the aspect of the four plots gets compromised
when I change the margin settings. I cannot use mtext
because I need to use colors for the text. I tried
layout, but wouldn't let me include

Hello,
I have been using scatter.smooth and been trying to format my plots

scatter plot points, but the line always stays black and solid. lty
has no effect.
When I specify par prior to calling scatter.smooth, col will change
