I've just installed Mandrake Linux, then compiled R-0.65.1 . Whether because I omitted some necessary items when I selected software for installion, or because they anyway needed to be loaded afterwards, I found it necessary to load the following packages in order to compile R-0.65.1 pgcc-g77-1.1.3-3mdk.i586.rpm (Fortran g77 compiler) XFree66-devel-3.3.5-3mdk.i586.rpm (X.h etc

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

Dear all, In RW0901 I could > dates("01/01/2000") [1] 01/01/100 where only the printing was wrong, but the double numeric representation of the chron object was calculated correctly but now in RW0990 > dates("01/01/2000") Error in fun(yy, ...) : must be 2-digit (numeric) year specification and also the followig doesn't help > dates("01/01/2000",

I observed the following difference: > ddd <- data.frame(a=1:3, b=1:3) # assignment of 'X' silently ignored > ddd[1,1] <- 'X' > is.factor(ddd[[1]]) [1] FALSE > ddd a b 1 1 1 2 2 2 3 3 3 # assignment of 'X' not ignored > ddd[[1]][1] <- 'X' > is.factor(ddd[[1]]) [1] TRUE > ddd a b 1 X 1 2 2 2 3 3 3 Regards > version

-- Happy holidays! -- Dear R Development Core Team, I want to thank you *very much* for the new "Writing R Extensions" manual published with RW0.901 and hope this is the right place to report some possible typos. page 17, example given in the middle of the page, I think it should read REAL(version) = 3.0; ^^^^^^^ page 23, second example, I think the parameter definition

In RW0.651 and RW0.901, I discovered some unexpected behaviour when I used as.matrix.data.frame() > matrix('"', 2, 2) [,1] [,2] [1,] "\"" "\"" [2,] "\"" "\"" > unclass(as.data.frame(matrix('"', 2, 2))) $V1 [1] "\"" "\"" $V2 [1] "\"" "\""

I have a question concerning memory. I understood that R takes a fixed amount of memory at startup (which I can influence with --vsize --nsize) and that gc() shows the memory still free of the total memory reserved for R. However, if I create a long vector of character data, gc() only seem to reflect the space needed for a vector of pointers to char, the space used for the character data itself

I observe dificulties with using data.frame(I(matrix)) > mat <- matrix(letters, 2, 2) > dimnames(mat) <- list(c(1:2), c("x","y")) > mat x y 1 "a" "c" 2 "b" "d" > dd <- data.frame(I(mat)) > ddd I.mat..x I.mat..y 1 a a 2 b b 3 c c doesn't look too bad, but, has

I just tried to batch-start rgui.exe (not rterm.exe) in a way, that it read.table()s data from a file with changing filename. As I understand no command line parameters are available for that, so instead I tried to pass the filename to an approbriate .RProfile, which works roughly, BUT ## this is my %R_USER%\.RProfile im <- read.table("d:/temp/im/temp.csv", header=TRUE,

I realise that there is an existing system for documenting datasets but what I would like is to be able to whack a few lines of commentary at the top of a file which contains data -- not full documentation but just an outline for myself to remind me of what I was doing or what settings I was using, etc. I was thinking that the read.table() function might be extended to support an option allowing

Can anyone give advice how to interactively exchange data between R and SQL-Databases like DB2, ORACLE, MS-SQL-Server ? If the answer is: 'currently not', this would be information for me as well. I will summarize to the list. Best regards -- Dr. Jens Oehlschl?gel-Akiyoshi MD FACTORY GmbH Bayerstrasse 21 80335 M?nchen Tel.: 089 545 28-27 Fax.: 089 545 28-10 http://www.mdfactory.de

Yesterday I asked for help about read.table with a CSV file. I received the following help. As always many thanks for the prompt responses. Now I load my csv file in a text editor ( pfe) and delete all spaces. My original mail is at the end. From: Peter Dalgaard BSA <p.dalgaard at biostat.ku.dk> Do you have spaces before the commas in your file? > Yes, number , space,

Hi, we have a first draft of R functions reading/writing data to XML files including a rather general DTD ... which borrows heavily from the data types of a certain programming language :-) The basic idea is to create an XML standard for data exchange, together with import/export functions for as many applications as possible. We here will need R, Matlab & Octave for our research program,

Duncan - (but sent to R-devel, for any other thoughts?) How do you envision RSPerl being used? Without having seen the details, I can think of playing with strings; is there a preferred incantation for stringification of R objects (serialization)? (actually, the main problem I'm having is that I know how I want to code something like: Robject <-
