Dear R-people, recently at s-news we had a discussion about factor(). I thought you might be interested in some of my thoughts about factors. Any comments welcome Best regards Jens Oehlschlaegel-Akiyoshi ------------------------------------------------------------------- I think the problem is deeper than that factors would just be handled inapprobriately by some S+ functions, the inconsistency is built in the constructor factor(), and thus is built in the concept! Let me cite S+ onli...

Hi, I'm trying to write a function to return an R vector which points directly to a contiguous subset of another vector, without taking a copy. Since SEXPREC is a header followed by the data, rather than the header plus a pointer to the data, I'm not sure what I'm trying to do is possible. Is there a way of doing this? Similar in spirit to how the R assignment "x=y" does

Before re-inventing the wheel I would like to ask: does anyone know about an optimizer in R which can reliably identify which value of X (Xopt) leads to Y (Yopt) closest to Ytarget in Y <- MonotoneStepFun(X) optionally with the restriction that Yopt <= Ytarget (at least if any Y <= Ytarget, otherwise any Yopt > Ytarget would be the preferred answer) If none is known, I will write

I like to have a continuously running R process, which can receive a dataframe from a client (over TCP/IP), does some processing, and sends some data back. What is the prefered way to do this? Using the socket interface? Using omega's CORBA stuff? Does anyone has example code for doing so? Thanks for any help Regards -- Dr. Jens Oehlschl?gel-Akiyoshi Analyse MD FACTORY GmbH Gr?nstr. 15

Here is a possible BUG with as.data.frame() and/or [.data.frame which broke Michael Lapsleys RODBC-Code. Can anyone confirm it is a bug or a 'feature' of the prototype? tablename <- "abc" a <- as.data.frame(cbind("abc", 1:3)) b <- as.data.frame(cbind(tablename, 1:3)) # ok > a V1 V2 1 abc 1 2 abc 2 3 abc 3 # missing column name > b tablename 1

As a complete newcomer I am attempting to learn to use R, but am finding it extremely difficult because I have not yet found an "Introduction to R". For over a week now I have monitored the R-help list, studied the R-FAQ and related documents, downloaded and run the Windows R and looked at the Help, downloaded early and late samples of the R-help archives, and searched for illuminating

Dear all, ? I don't know if you consider this a bug or feature, but it breaks reasonable code: 'unlist' and 'sapply' convert 'ordered' to 'factor' even if all levels are equal. Here is a simple example: o <- ordered(letters) o[[1]] lapply(o, min)[[1]]??????????# ordered factor unlist(lapply(o, min))[[1]]? # no longer ordered sapply(o, min)[[1]]??????????# no

Thanks for the replies and for confirming my suspicion. Interestingly, src/include/S.h uses a trick: ?? #define longint int and so does the nlme package (within src/init.c).
