This may be an FAQ, but a (perfunctory) search failed to turn it up. Suppose I have a function foo(...){<something>} and I want to obtain, inside foo, the names of items comprising the ``...''. E.g. if I call foo(melvin,clyde,irving) I want to be able to loop through the ``...'' and successively obtain the text strings "melvin", "clyde", and

If one specifies new options in a package, using the options() function, where does/should one document these new options? E.g. suppose that I put the line options(melvin=42) in a file zzz.R in the R directory of the package source, where the package contains functions foo(), bar(), clyde(), and irving() which all query options("melvin") and take some action based on the value of

I gather from reading the back-issues of r-help that it should be possible (modulo a number of caveats) to read an excel (yuck!) file into R using RODBC. I have obtained and installed ODBC and the RODBC package, but cannot for the life of me figure out how to go about it. Can anyone give me a simple recipe? I have an excel file on cdrom, say: /mnt/cdrom/melvin.xls I have started R and loaded

I am trying to build a function in a context where the environment concept would appear to be useful. But I'm a bit foggy about this concept and would appreciate some pointers and advice. Basically the function I'm building, say foo(x,t), is a function of two variables). Depending on the value of t, foo will return one of the values f1(x), f2(x), ..., fk(x), where each of f1, ..., fk is

Dear R list members I am trying to improve a boxplot with 2 data sets. I run somethinkg like boxplot(data1 ~ month, add=F, col = "red", ...) boxplot(data2 ~ month, add=T, col = "blue", ...) The problem is that the data from February are missing for data2, so R think that must take little more space between the data classes in data 2 and then both data gropus are not aligned.

I've just installed version 1.4.0 of R, and am experiencing a puzzling phenomenon with the library() function. I have .lib.loc set as follows: > .lib.loc [1] "/usr/local/lib/R/library" "/home/faculty/rolf/Rlib" If I invoke > library(melvin) I get the error message Error in library(melvin) : There is no package called `melvin' but if I invoke >

Hi, How to save an R object for example a matrix or vector and not all objects created in a session (which is usually performed by save.image or q("yes"))? Best, Carol [[alternative HTML version deleted]]

Thank you for you help. I tried your tips but the problem remains. Example: $ echo "SendEnv LANG LC_ALL" > ~/.ssh/config $ LANG=C; export LANG; LC_ALL=C; export LC_ALL $ ssh aa at quercy You are required to change your password immediately (root enforced) Last login: Fri Oct 30 15:02:34 2015 from quercy WARNING: Your password has expired.

Dear forum, I would like to use the kernel2d or spkernel2d in the Splancs-package, but it does not recognize my polygon data.

Invalid poly argument The data are defined as follows: polgonprov<-list(x=polyprov$X, y=polyprov$Y) with X and Y coordinates in the Lambert1972

Dear users, is anybody of you aware of a R command to perform laplace transform or even its inversion? Thank you very much. Luca
