...i.e. is it any different from building packages without `methods'?) or perhaps an R-help thread I should look for? In short, how should I setup my package so that my methods do not show up in the global workspace?

In R 1.9.0 on Solaris/Sparc when I run, for example, install.packages("gregmisc", "~/R-local/lib"), instead of installing the `gregmisc' package in the directory /users/student/rpeng/R-local/lib the package gets installed in /users/student/rpeng/\~/R-local/lib, so the directory \~ is created in my home directory. This doesn't happen to me on Linux or Windows so I thought it might not be an R problem. I realize I'm referring to an older version of R but I was wonder...

I've noticed a change in the way grep() behaves between the 1.9.0 release and a recent R-patched. On 1.9.0 I get the following output: > x <- dget(file = url("http://www.biostat.jhsph.edu/~rpeng/names.R")) > length(grep("^l\\w+tmean", x, perl = TRUE, value = TRUE)) [1] 84 And on R-patched (2004-06-11) I get > x <- dget(file = url("http://www.biostat.jhsph.edu/~rpeng/names.R")) > length(grep("^l\\w+tmean", x, perl = TRUE, value = TRUE)) [1...

R 1.6.1 on Windows NT4: The boxplot() function appears to draw its own tick marks and axis values even when called with add=TRUE. As a toy example, try x <- rnorm(100) f <- factor(rep(1:4, each=25)) plot(c(0,4), c(-3,3), type="n", xaxt="n", yaxt="n") boxplot(x ~ f, add=TRUE) My expectation is that a high-level plotting function will not mess with the axes

Dear Experts, I need to calculate the cdf of the standard normal distribution, i.e. H(x) = 1/sqrt(2*pi) integral(exp(-z^2/2) dz), where z is b/w -infi to infi. I know there should be a way to do it in R, but did not know to do it. I'd appreciate any help you could offer. Charlie Liu Graduate student intern at EPA/ECO

r-help, I can't seem to get the below data organized in such a manner so as to generate a contour plot using any of the functions {lattice.contourplot, base.contour, base.filled.contour}.

Hi, I'm a new R user. My goal is to do a variogram using geoR. I started by trying to do the example in the geoR Illustrative Session using my own data. I am able to read in my Ascii data using: D <- matrix(scan("file.dat", n=530*3), 530,3, byrow=TRUE). Then I use: as.geodata(D, coords.col=1:2, data.col=3) to make the object D geodata. I check the descriptive statistics,

Hi all, Although R seems to have jpeg() and png() functions that converts data into jpeg and png formated files, it doesn't have functions the other way around. Does one of R contributed packages have gif, jpeg and png image readers?

cut.Date and cut.POSIXt indicate that the breaks argument can be an integer followed by a space followed by "year", etc. but it seems the integer is ignored. For example, I assume that breaks = "3 months" is supposed to cut it into quarters but, in fact, it cuts it into months as if 3 had not been there. > d <- seq(Sys.Date(), length = 12, by = "month") >
