R> order(1, na.last=NA) Error in apply(sapply(z, is.na), 1, any) : dim(X) must have a positive length This bug appears unrelated to PR#1906, and so the fix of 8/15 doesn't help. It comes from the line inside order(): ok <- !apply(sapply(z, is.na), 1, any) where z=list(1) in my example. sapply() returns a single-element vector, not a matrix, making apply() unhappy. This might

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:

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

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

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

Hi all, After replying to r-help earlier today on the merge() related thread, I noted a trivial grammatical error in the description for the 'suffixes' argument in it's help file. A patch against the current SVN trunk version of merge.Rd in ..library/base/man is attached and pasted here: --- merge1.Rd 2016-06-08 13:34:35.000000000 -0500 +++ merge2.Rd 2016-06-08 14:03:34.000000000

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

It seems to me that colClasses = "logical" in read.table produces incorrect results when the input file has `1' and `0' in it. Although, it is perhaps just as likely that I am misunderstanding the documentation. Here is a simple example: > file.show("test.txt") x 1 0 1 > read.table("test.txt", header = TRUE) x 1 1 2 0 3 1 This result is fine. >

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

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

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

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 <-

This seemed too advanced for r-help and is related to the recent discussion of character vectors in dataframes. Following Brian Ripley's most excellent advice, we are moving to a world in which character vectors in dataframes are always of class AsIs. The cool way of doing this seemed to be the following: > cat(c("x", "y", "z"), file = "test.txt",

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

Hi all, R> seq(-.4, .8, length=7) [1] -4.000000e-01 -2.000000e-01 5.551115e-17 2.000000e-01 4.000000e-01 [6] 6.000000e-01 8.000000e-01 Well that may not be a "bug", but it has this unfortunate consequence: R> pretty(c(-.4,.8)) [1] -4.000000e-01 -2.000000e-01 5.551115e-17 2.000000e-01 4.000000e-01 [6] 6.000000e-01 8.000000e-01 And thus my plot axes look funny
