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.

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

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 ?

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.

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

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 -- Federico C. F.

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 -- Jose

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!

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 =

Hi, wbinfo -Y BUILTIN\group can work without idmap_rid in Samba-3.0.14a. But I'm experiencing wbinfo -Y with idmap_rid failed for SID to GID conversion of BUILTIN groups. Since idmap_rid only works in a single domain, and captures workgroup's domain sid as a real domain sid in rid_idmap_get_domains(), when running "wbinfo -Y BUILTIN/System Operators", the function
