I am including an external piece of software in an R package. This software ships with its own configure script generated by autoconf/automake, and this script is being run as part of the package configure script. The package contains a file m4/lt~obsolete.m4 which - as far as I can see - is a standard file from the autoconf/automake/m4 suite of programs. A warning is generated with R CMD

"lpt1" through "lpt9" and "com1" through "com9" are in fact "special" file names under various versions of Microsoft Windows. However, "R Extensions" says only that "lpt1" through "lpt4" and "com1" through "com3" cannot be used as filenames, and "R CMD check" checks for just these

Dear all, I have a problem with constructing a nested loop. I have two matrices: pnr: 800 rows 14 columns where rows are 40x20 meaning that 40 rows belong to one of twenty objects in the matrix pnr mvp: 20 rows and 14 columns I want to: calculate a distance value with the first 40 rows of pnr but 20times with the 1st row of mvp then the next 40 rows of pnr and 20times with the second row

Dear List, today I turn to you with a next problem. I'm trying to compare species richness between various datasets (locations) using species accumulation curves (Chapter 4, page 54 in Tree diversity analysis<http://www.worldagroforestry.org/treesandmarkets/tree_diversity_analysis.asp>by Kindt & Coe). To accomplish this I'm using package BiodiversityR. My data is comprised of

Hi, I?d like to ask about bug 17159: https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17159 I can confirm that I see exactly this bug when using dir.create on paths of UNC form (\\server\share\xxx), with the recursive flag set. I?m seeing this when attempting to use install.packages with such a path (which I know isn?t supported, but would be great if it was!). I can see that a patch has been

Dear List, I'm having problem with an exercise from The R book (M.J. Crawley) on page 567. Here is the entire code upto the point where I get an error. data(UCBAdmissions) x <- aperm(UCBAdmissions, c(2, 1, 3)) names(dimnames(x)) <- c("Sex", "Admit?", "Department") ftable(x) fourfoldplot(x, margin = 2) dept<-gl(6,4) sex<-gl(2,1,24)

Hi, I am trying to use piecewise linear regression to approximate a nonlinear function. Actually, I don't know how many linear functions I need, therefore, I want build an array of regression models to automate the approximation job. Could you please give me any clue? Attached is ongoing code: rawData = scan("c:/zyang/mass/data/A01/1.PRN", what=list(numeric(),numeric())); len =

I usually draw a complete blank if I try to assist our IT department with such issues (we really need better documentation than the Admin manual for large-system installs by non-experts in R). However, it is my impression that there are also options involving environment variables and LFS naming. E.g., map the networked user directory to, say, a P: "drive" and make sure that the

Hi all, I have setup with linux samba-server(ver 2.2.1a) as my print-server under user security model with printer access allowed only for a few users.

However it is fine with normal shared folders ,where only the valid user are able to

Here are the details: 1) NT based clients can log on as guests or as users and can print in either case with no problems. 2) Windows 9x clients can log in as either guest or as users and can access shares with no problems. 3) Windows 9x clients attempting to print directly to the SAMBA printer hang the print process and

Hi List, I'm having problems installing certain packages. When I try to install fields, I get the output below. I have highlighted the what I perceive as the first error (spam seems to be a dependency of fields). Can I assume this is causing dependency problems for fields, which fails to install at the end, or is there a deeper problem? I run Ubuntu Karmic Koala on R 2.9.2. 2>
