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

Sorry, I was commenting on the previous windows version (version file says 0.5a) (the first one which ran under RW.1.0.0) I have Win NT 4.0 Service pack 5 and R is > version _ platform Windows arch x86 os Win32 system x86, Win32 status major 1 minor 0.0 year 2000 month February day 29 language R > -----Original Message----- > From: Prof Brian

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

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",

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.

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] "\"" "\""

Some days ago a problem with perl under WinNT was reported, which lead to > > t1 <- read.fwf("d:/maj/consulting/MarkStevens/matrix.txt", width=c(4, 22, > rep(7, 8))) > Error: "scan" can't open file I installed perl from the WindowsNt Recource Kit CD (Sept. 98) and encountered the same problem: Scan couldn't open the file - because perl did not produce

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 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,

Hi Martin, Great that you follow this. My original intention was to be able to translate colornames to hsv because this would allow using colornames to cut out a certain part of the colorwheel for colorcoding (HSV component H, see my code below) I think internally we might have colors represented as Colornames, ColorIntegers, ColorHexcodes, ColorRGBs, ColorHSVs (ColorCMYs?) however the R-user

Dear R-people, Did anyone succeeded in using R sockets under Windows NT? Yesterday I could establish client and sever sockets with R-0.65.0 under linux, but with R-0.64.2 under NT I can't. I use Windows NT 4.0, Service pack 5, with tcp/ip protocol installed. Any help appreciated (I will summarize to the list) Best regards -- Dr. Jens Oehlschl?gel-Akiyoshi MD FACTORY GmbH Bayerstrasse 21

Thank you Thomas, it really works and I was blind! >The offending line is > >if (length(port <- as.integer(socket$socket)) != 1) > stop("invalid `socket' argument") > >and socket$socket needs to be changed to x$socket -- Dr. Jens Oehlschl?gel-Akiyoshi MD FACTORY GmbH Bayerstrasse 21 80335 M?nchen Tel.: 089 545 28-27 Fax.: 089 545 28-10

Does anyone know about functions for calculating Somer's D in R? Perhaps even a version for censored values, like the two functions in hmisc?

Hi, can anyone help with two questions concerning persp? (1) Is there a function in R to project points onto a persp() plot, as is in S+ (perspp() I think) ? (2) How can I label and tickmark axes x,y and z in a persp plot? (I am still using RW065) Thanks for any help -- Dr. Jens Oehlschl?gel-Akiyoshi MD FACTORY GmbH Bayerstrasse 21 80335 M?nchen Tel.: 089 545 28-27 Fax.: 089 545 28-10
