Hello, I'm adding a private library tree in my home directory by adding this to my ~/.Renviron: R_LIBS="~/R/library:${R_LIBS}" so that once in R: R> cat(Sys.getenv("R_LIBS"), "\n") ~/R/library:/usr/local/lib/R/site-library:/usr/lib/R/site-library:/usr/lib/R/library Is this the best way to proceed? Cheers, -- Sebastian P. Luque

I have been lurking in this list a while and searching in the archives to find out how one learns to write fast R code. One solution seems to be to write part of the code not in R but in C. However after finding a benchmark article (http://www.sciviews.org/other/benchmark.htm) I have been more interested in making the R code itself more efficient. I would like to find more info about this. I have

Hi, Is there some alternative to cumsum for chron objects? I have data frames that contain some chron objects that look like this: DateTime 13/10/03 12:30:35 NA NA NA 15/10/03 16:30:05 NA NA ... and I've been trying to replace the NA's so that a date/time sequence is created starting with the preceding available value. Because the number of rows with NA's following each available

Hello, Has anybody been able to successfully install MS Office XP Pro in Wine? I don't care much about the whole suite, I need MS Access, but since I have a bundled cd, I don't have much choice. Apparently several folks have had similar problems in this list, and I haven't found solutions. Wine-version is 0.0.20041201-1 Debian unstable package. I'm not sure I'm starting the

Hi all, Does anybody know whether one can nest an 'if' statement in a 'for' loop. According to the results of my code, the for loop is performed first, but I'm not sure I got something else wrong with my code. I'm trying to perform the if statement for each step of the for loop. Thanks in advance. Best regards, Sebastian

Hi, I have a 3 panel xyplot with different variables in the y axis. I'm trying to insert a newline after "Width (cm)," in the ylab argument as in the example below. My goal is to have the y axis label broken into two lines, split after the string just mentioned. plotfun <- function() { fakedf <- data.frame(A = sample(1:100, 50), B = rnorm(50),

Hi, Is there some alternative to the 'groups' argument in lattice's bwplot function for boxplots? Say in the example below: bwplot(yield ~ site | year, data = barley) you want to have two side by side boxplots per site, corresponding to each year in the barley data frame. Ideally, the space between boxplots of the same site should be smaller than that between boxplots of different

This is possible with POSIX classes too by using the structure() function, but a post by Brian Ripley to the effect that it may not be practical in the long term further convinced me of this. -- Sebastian P.

Hi, I'm trying to establish a connection to a MySQL database, and am using the rodbc package for it. This is in a GNU/Debian Linux box, with the corresponding Debian unstable packages. I can login to my MySQL databases from any shell and directory, so the problem is probably not there. Here's an example of what I'm doing: R> odbcConnect("test",

Dear List, I've tried to set default par() in .Rprofile by putting the following in the .First function: setHook(packageEvent("graphics", "onLoad"), function(...) {graphics::par(cex.axis=1.5, cex.lab=2, las=1)} ) My goal was to set par() defaults without opening a device everytime at startup. However, the next plot I create doesn't show these

I'm trying to make my R scripts more readable by others, so I searched for some R programming conventions and found the following two: - http://www.ci.tuwien.ac.at/Conferences/useR-2004/Keynotes/Maechler.pdf - http://www.maths.lth.se/help/R/RCC the latter being quite extensive. Are there some other sources that might be useful? Thanks in advance, -- Sebastian P. Luque

I'm having trouble understanding how functions in the subset argument for lmList search for the objects they need. This trivial example produces "Error in rownames(fakedf) : Object "fakedf" not found": library(nlme) fitbyID <- function() { fakedf <- data.frame(ID = gl(5, 10, 50), A = sample(1:100, 50), B = rnorm(50))

Hello, I have been searching for ways to obtain these for combinations of fixed factors and levels other than the 'baseline' group (contrasts coded all 0's) from a mixed-effects model in lme. I've modelled the continuous variable y as a function of a continuous covariate x, and fixed factors A, B, and C. The fixed factors have two levels each and I'd like to know whether
