I am trying to replicate part of the function of the S-Plus terms.inner function. I don't need an entire model terms object but R expressions or character strings containing the innermost variable name given a vector of character strings or expressions. Here are some example inputs that each should result in the string or expression "x": x; x^2; g(x); h(g(x)); h(g(x^3));

I am using read.spss in the foreign package to read an SPSS save file. For date variables I get huge values such as 11489990400. Does anyone know how to convert these values to R POSIXct date objects? Thanks in advance -Frank platform i686-pc-linux-gnu arch i686 os linux-gnu system i686, linux-gnu status major 1 minor

In S-Plus the ... argument for tapply is before simplify. In R (1.2.3) ... is after simplify, causing the user to have to specify simplify every time ... is used even though the default is usually OK. Unless there was a benefit to reordering the arguments, it might be a good idea to reconsider the current function definition. ... is probably used more than simplify (e.g., tapply(rainfall,

Dear R Developers, I should have had the Design library running in R by now but have kept putting off changing some calls to LINPACK routines to use those builtin to R. Specifically I call dqrsl1 and dqr. Would it be an easy task to put those in the next release of R? If not I'll finally bite the bullet and get back into reading LINPACK documentation (which I have but haven't examined

I have many functions for high-level plotting that early on in their code do something like strwidth('string', units='inches') before plotting. I do this before plot() to set the correct margins with par(mai=...), to leave room for wide text on the left or right margins. If the plotting device is not opened strwidth( ) causes an error that plot.new() needs to be called. I can

In a .First.lib I want to issue two require()s to insure that two other packages are loaded. But I want the package being loaded by .First.lib using library.dynam("mypackage",pkb,lib) to be higher in the search order than the two required packages, because I want to have a couple of functions from the two required packages overridden. What is the best way to do that? Thanks in advance

Dear Jan, Thank you very much for your excellent description of the problem and the self-contained test code. This is a problem that I've been meaning to either document better or solve for some time. The root of the problem is with the builtin S-Plus terms.inner function: > attr(terms.inner(asthma ~ pol(age,kx) + smok),'variables') expression(age, kx, smok) You can see that

I installed the new rpm from CRAN for R 1.4 for Mandrake Linux 8.1, after getting blas and libgcc from rpmfind.net. When I do update.packages() the system goes to update grid, lattice, and mgcv. I get compile errors for two of them. Apparently R is looking for gcc 3.0.1 or later but 8.1 uses 2.9x which is required for other Mandrake applications (i.e., I get a dependency error when trying to

If anyone has a very fast vectorized method for doing the following I would appreciate some help. I want to avoid outer() to limit memory problems for very large n. Let x = real vector of length n y = real vector of length n w = real vector of length m, m typically less than n/2 but can be > n z = real vector of length m For w[i], i=1,,,m, find the value of x that is closest to w[i].

Great news! Having spent a significant amount of time porting/mantaining some packages on S4/Splus 5.x and R, I'm interested in your experience as you port Hmisc and Design; I'd like to know of your progress in order to help improve available R/Splus portability tools both at the C and the S language code. These tools include the package SLanguage written by John Chambers, and

I saw an ad in the July 2001 Amstat News for a complex sample survey analysis package called Wesvar. The package has what appears to be a useful feature called a "Workbook" by which the user navigates analysis output. This is a hierarchical tree in which the user may click on a part of the analysis (table, regression fit, descriptive stats, etc.) so as to go directly to that output.
