similar to: order(1, na.last=NA) fails (PR#1913)

An NA in the rownames of a matrix (or dataframe) causes misalignment when the matrix is printed: R> x <- matrix(1:12, 3,4, dimnames=list(letters[1:3], LETTERS[1:4])) R> rownames(x)[2] <- NA R> x A B C D a 1 4 7 10 <NA> 2 5 8 11 c 3 6 9 12 The bug is in function Rstrlen, in src/main/printutils.c. MatrixRowLabel and MatrixColumnLabel (same file) rely on Rstrlen

Environment variables set with Sys.putenv() disappear (i.e. become "") after a while, especially after heavy-duty I/O. Example: R> x <- matrix(1., 3000, 3000) R> save(x, file="myx.RData") R> Sys.putenv(HOME="/tmp") R> while (Sys.getenv("HOME") != "") {cat("ok\n"); load("myx.RData")} The loop prints

Under R-1.5.0 on Solaris 2.6: R> prettyNum(123456789, big.mark=",") [1] ",123,456,789" and that bad behavior (leading comma) spills into formatC as well: R> formatC(123456789, digits=0, format="f", big.mark=",") [1] ",123,456,789" Looks to me like a bug in src/library/base/R/format.R, in function prettyNum: B.[i.big] <-

R> round(100000/3, -2) - 33300 [1] -7.275958e-12 I would have hoped for 0. The problem seems to be specifically for negative "digits". This is in 1.3.1 on Solaris 2.6 (full description at bottom). [Apologies for making everyone read this 3 times; my bug.report() burped.] Peter Dalgaard <p.dalgaard@biostat.ku.dk> says the problem is in fround.c, which reads in part:

In R-1.5.0pre (2002-04-08) on Solaris 2.6, the window that X11() creates has a title like: R Graphics: Device 2 (ACTIVE) o iyeP )( y except the funny characters at the end have umlauts and other accents (i.e. extended ASCII characters), and they may be different each time X11() is invoked. There is no loss of functionality; it just looks a little ugly. I saw this behavior in R-1.3.?, it

Hello, When I merge two dataframes, each created by read.table and containing no factors, the result has columns which have been converted to factor. I think this is a bug (and may be related to some fixed bugs, eg PR#1102, PR#1121), but will await comments before submitting. Also, I'm not sure if the bug is in merge() or in read.table(). I am using R-1.4.0 patch 1/13/02 on Solaris 2.6.

On Oct 22, I sent an empty bug report (#1138) because bug.report() "ate my message". Paul Gilbert opened a new bug report (#1158) for this problem. I'm now convinced it's because I had an apostrophe in the subject line ("round() doesn't"). The bug.report documentation specifically warns against this, but the bug.report() function could also check for it! I

Environment variables set with Sys.putenv() "disappear" spontaneously (and somewhat randomly) when I load large datasets. This was reported in R-help by Dave Kane on June 4, 2001; I have not seen any further discussion. I'm not sure if I can report it as a "bug", since it is not entirely reproducible. Could someone try this and see if you have trouble too? The following

I want to put multiple plots on a page using par(mfrow), then a single title at the top. This should work, but doesn't: R> par(oma=c(0,0,4,0), mfrow=c(3,4)) R> for (i in 1:12) {plot(1); title(i)} R> ## text(10,10, ".") R> par(mfrow=c(1,1), oma=c(0,0,1,0)) R> title("Main Title") The main title does not appear. However, uncommenting the third line

If all rows are in the same "group", rowsum() returns a vector instead of a (1xN) matrix, contrary to documentation: R> print(z <- rowsum(matrix(1:12, 3,4), rep("x",3))) [1] 6 15 24 33 R> dim(z) NULL It worked correctly in version 1.4.0 but was broken by version 1.6.1. I'm currently using 1.7.1 under Solaris 2.8. --please do not edit the information

The result of rowsum() in R doesn't have the dimnames I'd expect, e.g.: > rowsum(matrix(1:12, 3,4), c("Y","X","Y")) [,1] [,2] [,3] [,4] 1 2 5 8 11 2 4 10 16 22 whereas S-Plus gives the more useful result: [,1] [,2] [,3] [,4] X 2 5 8 11 Y 4 10 16 22 This is because R's rowsum() code gives the

Hi, all! My project today is to write a speedy colSums(), which is a function available in S-Plus to add the columns of a matrix. Here are 4 ways to do it, with the time it took (elapsed, best of 3 trials) in both R and S-Plus: m <- matrix(1, 400, 40000) x1 <- apply(m, 2, sum) ## R=16.55 S=52.39 x2 <- as.vector(rep(1,nrow(m)) %*% m) ## R= 2.39 S= 8.52 x3 <-

You get a warning message when you specify a ylab parameter while plotting data whose x's are POSIXct values. Apparently the `axis.POSIXct' method tries to reset the ylab---via the ... parameter---after it has already been set by higher level methods. Here is a function that illustrates the problem. ylabProblem <- function() { x <- ISOdate(2003, 4, 1:10) # POSIXct

In prior versions, as recent as R-1.5.0pre (2002-04-08), Tcl/Tk support worked just fine, with "configure" (no flags) finding /usr/local/lib/tclConfig.sh and /usr/local/lib/tkConfig.sh. In Monday's official release of R-1.5.0, Tcl/Tk support now fails for me (under Solaris 2.6): ... checking for tclConfig.sh... no checking for tclConfig.sh in library (sub)directories... no

I don't seem to be able to initialize a vector of NAs. I hope this is a bug and not a new feature (I realize I have not paid much attention to a lot of recent discussion about NA): platform sparc-sun-solaris2.6 arch sparc os solaris2.6 system sparc, solaris2.6 status major 1 minor 5.0 year

as.character.factor contains this line (where cx=levels(x)[x]): if ("NA" %in% levels(x)) cx[is.na(x)] <- "<NA>" Is it possible that this is no longer the desired behavior? These two results don't seem very consistent: > as.character(as.factor(c("AB", "CD", NA))) [1] "AB" "CD" NA > is.na(.Last.value)[3] [1] TRUE

Hey everyone! I am seeing strange behavior with NA in the rownames of dataframes: > a <- data.frame(1:3, row.names = c("r1", NA, "r3")) > cbind(a) X1.3 r1 1 <NA> 2 r3 3 Everything works. The peculiar thing is that when the NA is in the first row, things no longer work as I would have expected: > b <- data.frame(1:3, row.names
