similar to: R-alpha: apply()

Here's something related to last week's apply() problem: R> x <- matrix(1:20, nc = 4) R> x [,1] [,2] [,3] [,4] [1,] 1 6 11 16 [2,] 2 7 12 17 [3,] 3 8 13 18 [4,] 4 9 14 19 [5,] 5 10 15 20 R> tapply(x, row(x), table) [1] Numeric,4 Numeric,4 Numeric,4 Numeric,4 Numeric,4 ??? In S, > tapply(x, row(x), table)

1. lbeta and beta do not work properly: lbeta returns its first argument and beta gives the lbeta result. In names.c lines 245-6, the codes for these should be 2 and 3 instead of 1 and 2 2. crtl-C does not work (except the first time) on Red Hat elf Linux (which has many many other problems as well) nor on the previous version of Linux for Amiga. It worked on Slackware aout Linux and now works

Perhaps someone can enlighten me here: R> x <- factor(LETTERS[1:3]) R> x [1] A B C R> mode(x) [1] "factor" R> class(x) [1] "factor" R> mode(unclass(x)) [1] "factor" S-PLUS has > x <- factor(LETTERS[1:3]) > mode(x) [1] "numeric" > class(x) [1] "factor" > mode(unclass(x)) [1] "numeric" ???

I think I am misunderstanding something about the identify() function. if we have an example such as this: > x_1:10 > y_1:10 > plot(x,y) > identify(x,y, n=1) [1] 2 3 > I clicked on two points and identify() returned both of them (2 and 3). The manual says n is the maximum number of points to be identified. If I specify n=1, should identify() return a single value?

Does R have a function like the S(plus) function, lmsreg, Least Median of Squares Regression? I am using R-0.61.

Hi, when designing libraries for R, is it possible to call C/Fortran subroutines from other dynamically loaded code? The following example crashes R: ********* fn1.c ***************** void twice(int *i) { *i = 2 * *i; } ********************************* ********* fn2.c ***************** extern int twice(int *i); void negtwice(int *i) { *i = -1 * twice(i); }

I am having some difficulties using dynamically loaded C functions on a Sparc 10 with R compiled using cc (both R-0.49 and R-0.50). I get sporadic errors with the error message: Error: character variables must be duplicated in .C/.Fortran, with C functions which pass character variables. my C functions look like: anyfunc(char **filename, other variables ) This error message appears about 25%

Attached is the current version of my sd2rd perl script. It has passed tests by Martin, Fritz and myself, and seems to work reasonably well (it should get the arguments lists right, distinguish between VALUE and VALUES, and know about REFERENCES and SEEALSO). Any comments etc are most welcome. -k ************************************************************************ #!/usr/bin/perl -w $\ =

To Whom It May Concern, I have been informed that there is a public domain software called "R" which is available through ftp://stat.auckland.ac.nz. I've tried the address but I can't find the software itself. Can you help me on this. Thanks.

Is this behavior correct? (R 0.49 on SunOS 4.1.4) > "a">1 TRUE > "a"<1 FALSE > "a"==1 FALSE > "a">2 TRUE > "a"<2 FALSE (I know, this is like the old joke: "Doctor, it hurts when I do this." "Well, don't do that!" But it might be useful to have this caught by an error or warning message
