Why ?rmvnorm not working
Hi,
My R version is 2.4.1 and I installed the the packages MASS and run
command library("MASS"),
however when I type ?rmvnorm, no help topic found, it worked before.
I tried to ype ?rinvgamma from "MCMCpack" which works great.
Anybody have idea? I also reinstalled MASS package, but when I try to type
rmvnorm(), no functions found.

'attach workspace' on R console File menu
Quite often I save misc functions and data objects as .RData files that I
can use in other sessions. Although I could 'Load Workspace" these files,
most of the times I prefer attaching them. It would be really convenient to
have a menu item under the File menu on the Windows R Console to allow
attaching workspaces, e.g.
--------------------
Attach Workspace...
Load Workspace...
Save

labels
Hello, I would like to add to axis labels special caracters. Instead of writing :plot(simul, xlab="beta", ylab="sigma11") It would be great if I could write something as in LaTeX :plot(simul, xlab="\beta", ylab="\sigma_{11}") Is there a way to do that ? Thank you

look for packages
Dear list members,
I am analysing some microarray data. I have got the differentially
expressed genes and now want to carry out PCA analysis to get the main
components that contribute to the variance.I have browsered the CRAN and
BioConductor and did not find an appropriate package.
Have anybody ever carried out PCA analysis? Is there any package about PCA
in R?
Thanks for your advice.

Removing Inf and Inf values from a fata frame
Hi,
I have a csv file with empty values, when I apply
the different functions (mean, std, etc.) I create a
new data frame, the empty values generate Inf and -Inf
values. How can I remove those Inf and -Inf values
from the new data frame? I already specified na.rm in
the mean and std functions, but the values are still
there.
Thank you,
Judith

fractional calculations
Hi All,
is there a function in R that allows me to work with fractions without
transforming them to floats (or whatever) in between?
Something that would calculate something like:
(1/2 + 1/8) * 1/2 = 5/16
without ever transforming to 0.5 and 0.125?
Best,
Federico

like apply(x,1,sum), but using multiplication?
Hi,
I need to multiply all columns in a matrix so something like
apply(x,2,sum), but using multiplication should do.
I have tried apply(x,2,"*")
I know this must be trivial, but I get:
Error in FUN(newX[, i], ...) : invalid unary operator
The help for apply states that unary operators must be quoted. I tried
single quotes too, with the same results.
Thanks,
-Jose

plotting command trouble
Dear R-Experts,
I have the following command lines:
windows()
plot(0:60, 0:0.896, type="n", xlab="Zeit [min]", ylab="Absorptionsmessung
bei 600nm",main="Zellwandstabilit?t" )
dev.off()
Can anyone say me why the plot command does not work and how the correct one should look like?
Important is: x-axis goes from 0 to 60 and the y-axis from 0 to 0.896!

Hiding "Warning messages" in coxme output
Dear list,
I have been trying to use coxme in R 2.3.1.
When I use coxme in the following data sim.fr1, i get
"Warning messages: using 'as.environment(NULL)' is
deprecated"
Why does it occur?
How can I hide such warning message,
especially when coxme is under a loop?

Replacement in an expression - can't use parse()
Dear all,
Suppose I have a very long expression e. Lets assume, for simplicity, that it is
e = expression(u1+u2+u3)
Now I wish to replace u2 with x and u3 with 1. I.e. the 'new'
expression, after replacement, should be:
> e
expression(u1+x+1)
My question is how to do the replacement?
I have tried using:
> e = parse(text=gsub("u2","x",e))
> e =
