In R-beta (Masked Marvel), when I do the example from the read.pnm help file, this is what happens: x <- read.pnm(system.file("pictures/logo.pgm",package="pixmap")[1]) Warning message: In rep(cellres, length=2): x is NULL so the result will be NULL In R-2.15.3, it's all right.

Hello! Over the weekend, I updated my RcmdrPlugin.qual package. It works fine on a 64 bit Windows machine but not a 32 bit. This is very strange. The new menu with all of the Quality Control stuff does not appear. Have any of you run into this sort of thing before, please? Thanks, Sincerely, Erin Erin M.

Dear Debian People: Is there a way to run a little script (on Ubuntu Manic Meerkat) every hour, please? I know that this is more of a LINUX/UNIX question rather than an R question. Sorry.

Dear R People: Is there a library for Multivariate time series, please? For some reason, I'm thinking that Dr. Paul Gilbert may have one? R Version 1.6.2 (i've updated!) for Windows Thanks so much! Sincerely, Erin Hodgess University of Houston - Downtown mailto: hodgess at uhddx01.dt.uh.edu

Dear R People: Here is an interesting question(I think) Suppose I want to calculate Centered Moving Averages; i.e. x[1] <- ( sum(y[1:12]) )/12 x[2] <- ( sum(y[2:13]) )/12 and so on. Of course, this is easily done through loops. However, I have been trying to do this more elegantly, but have failed. I have tried things like j1 <- 1:109 j2 <- 12:120 x[1:109] <- ( sum( y[j1:j2])

Dear R Debian People: I have put this on regular R help as well, but thought that I'd try here too. I updated to R-2.10.0 on Ubuntu Karmic Koala via apt-get update, apt-get install. Then I had a problem that said that I need MASS <= R-2.9.2. Fair enough. Uwe Ligges was kind enough to point out that I needed to use > update.packges(checkBuilt=TRUE) So I did. Now the menu on Rcmdr

Hi again. On Windows, when I try to use the "install packages" from the menu, there is no Rcmdr and no RcmdrPlugins to be seen. thanks, Erin Erin M.

Dear R Developers: Why is it that the singular value decomposition is used when running regression with arima, please? I've been looking for a reference for that but have come up empty so far.

Dear R Development People: I was trying to build R-2.12.2 from source on a Windows XP machine. Doing the make all recommended works fine, but building the bitmap dll is a problem. It seems to be in the libpng directory. I got libpng-1.5.1, and untarred it. However, there is no makefile.mingw file in the scripts directory. I then obtained a version of libpng-1.4.5, and the file is there.

Dear R People: I have the source for R version 1.1.1 on a UNIX system alpha-dec-osf4. The ./configure works fine. When I do the make, it works fine until it tries to build the package tcklc.

Dear R People: I am drawing graphs for a College Algebra class. I would like to have the x and y axes, along with the lines that I am plotting. So I leave off the axes, and use xlim and ylim.

Dear R People: When the D function is used for a symbolic derivative, an expression is returned, which is fine. How do you change that expression to a function, please?
