similar to: round() doesnt (PR#1138)

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:

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

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

Hi, all, In PR#1138 and PR#1139, I pointed out that round() with digits<0 would not actually round to an integer. Brian D. Ripley (hereafter BDR) fixed it in R-1.4.0, but the fix introduced a new error, PR#1254 (caught by Ole Christensen). BDR (I'm guessing) fixed the fix; here's the relevant line from fround.c: if(dig <= 0 && fabs(res) < 1e9) res = (int)floor(res +

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

After reading Cal Henderson''s article on Vitamin Serving Javascript Fast<http://synthesis.sbecker.net/articles/2006/06/03/www.thinkvitamin.com/features/webapps/serving-javascript-fast>I was immediately inspired to create a plugin to easily facilitate this in Ruby on Rails. I whipped up most of it right then, and finally got around to polishing it for release today. Told myself I

Hi, I have made a tiny package for saving dataframes in ASCII format. The package contains functions save.table() and save.delim(), the first mimics (not completely) write.table() and the second uses just different default values, suitable for read.delim(). The reason I have written the functions is that I have had problems with saving large dataframes in ASCII form. write.table() essentially

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] <-

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 <-

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

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

I am trying to upgrade to the LLVM v4.0 branch, but I am seeing failures in my TableGen descriptions for conversion from FP32 to FP16 (scalar and vector). The patterns I have are along the lines of: [(set (f16 RF16:$dst), (fround (f32 RF32:$src)))] or: [(set (v2f16 VF16:$dst), (fround (v2f32 VF32:$src)))] and these now produce the errors: error: In CONV_f32_f16: Type inference

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
