None of this is greatly important but might be a bit useful to someone. BTW, I have 0.99a installed, it compiled without a problem. I've discovered most of the plotting facilities including the legend() function and the various text annotations, this is nice an convenient and flexible enough to do most things. One thing that I must say is that the help pages on plot() and plot.default()

Here is a possible BUG with as.data.frame() and/or [.data.frame which broke Michael Lapsleys RODBC-Code.

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

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.

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'm a bit confused about the nls package, I'm trying to use it for curve fitting. First off, the documentation for nls says ``see `nlsControl' for the names of the settable control values'' -- this is wrong, it should be nls.control (minor point but had me confused for a moment). Now I'll try something very simple (maybe too simple):

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

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,

For a long time now I've been using a function: classed <- function (x, cls) { class(x) <- cls x } as a utility at the end other functions to set the class of an object and return the object. I've noticed examples where others have been doing a similar thing and I think it would be a useful addition to R base (unless there is already something there to do this - it

Hi, When trying to generate very long strings, my R hangs without any error message, even if given much memory. # e.g. x <- character(10) for (i in 1:10) x[i] <- paste(1:1000, collapse="abc") paste(x, collapse="") # or directly paste(1:10000, collapse="abc") Am I violating any max(nchar(character())) or is this a bug? Regards Jens Oehlschl?gel-Akiyoshi

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

Hi, below is a function which pastes a matrix, but uses parsing (deparse(substitute()) and eval()). Does anyone know a more standard solution to pasting a matrix?
