Charts to M$Word - what's the best format
Hi
I'm exporting some graphs from R to M$Word. I used png, jpeg and bmp and
the quality is poor when comparing with the postscript.
What is the best way to export a chart to be included in a M$Word file ?
Thanks

Excluding rows from a matrix
Hi
I have a matrix (4 x 950) and I want to remove 3 rows, where the values
from the first column are 713, 714 and 715. I can select the rows, one
by one, with
mat[mat$first==713,]
mat[mat$first==714,]
...
but I'm unable to (i) select the 3 rows at once, (ii) select the matrix
excluding those rows.
How can I do it ?
Thanks

How to organize/develop an R function
Hi
Maybe this is not an issue about R. It's probably a programming issue
and I am not a developer at all. Anyway my main developing activities
are in R and that's where I have difficulties.
When I develop a function or group of functions I lose eternities with
the objects attributes and classes. I do a lot of object manipulation
(lists to arrays, factors to numeric vectors, etc, etc) so

shapiro.test
Hi
The shapiro.test function outputs a value of the W statistic, which
should be 1 if the distribution is normal, and a p-value for the test
(as the documentation states).
I'm a bit confused with some results. I'm getting a W=0.9977 and a
p-value=0.1889.
I was expecting that a W of 0.9977 would tell me that the distribution
is normal so p-value should be small ...
What am I missing ?

R under suse linux 9.3
Hi, dear list members,
I've been using R under windows XP and I am now changing
my system to SUSE LINUX 9.3.
I could figure out that there is no precompiled version
of R for LINUX. To get me going, I would like your help
regarding what I need to setup R under my SUSE LINUX.
Which compiler do I need to be able to compile the source
and I was wondering if I could get GNU compiler?

problem with do.call
Hi
I'm writing a function that uses four parameters (scalars) and I need to
run it in an iterative process (the parameters vary to find the minimum
RSS).
I don't want to use loops and so tried the do.call function. However it
didn't work. My understanding is that the do.call simple runs the
function replacing the arguments (scalars by vectors), instead of runing

Error handling
Hi
I wrote a function implementing an algoritm for simulation of spatial
sampling plans (using geoR).
I'm using a range of parameters to perform several simulation and
sometimes this parameters create function errors wich cause the algoritm
to stop.
How can I avoid this ?
Below there's a small example that I made to study the problem but I was
not able to solve it. I've tried
