similar to: Misalignment of <NA> in rownames (PR#1905)

R gurus, Every so often(*) someone asks how to suppress scientific notation in printing, so I thought I'd give it a shot, but I need some help. The formatting decision is made(**) on line 286 of src/main/format.c : if (mF <= *m) { /* IFF it needs less space : "F" (Fixpoint) format */ where mF is the number of characters for "normal" printing and *m is the number

Hello everyone, Apologies in advance if you have received this multiple times! On a thread similar to that posted by Don MacQueen (http://www.r-project.org/nocvs/mail/r-help/2002/3455.html): is there any way to nicely format NA's when listed as rownames? When NA's are part of rownames, the alignment is thrown off: > z <- matrix(c(100, 200, 300)) > z [,1] [1,] 100 [2,]

Hi, We sometimes see offers to contribute, asking what needs to be done. If they know C, how about the 111 FIXMEs? But which ones would be most useful to fix? Which are difficult and which are easy? Does R-core have a process to list and prioritise the FIXMEs? ~/R/Rtrunk/src/main$ grep "[^/]FIXME" * | wc -l 111 ~/R/Rtrunk/src/main$ grep -A 1 "[^/]FIXME" * arithmetic.c:/*

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

Ben, Thanks for the bug report. I am off two minds about it as discussed below. But as it does indeed create a crash / segfault, I am passing this on to the R bug tracker. A suggested two-line patch is below; I tested the patch against a 'vanilla' 2.6.1 source tree.

This maybe a basic question, but I have spent several hours researching and I could not get an answer, so please bear with me. The problem is with time series in the package tseries. As the example below shows, the time series can get misaligned, so that bad results are obtained when doing regressions. I found a way to do this correctly, but I find it rather cumbersome. My question is: is there a

Dear R-help, I am trying to overlay a secondary y-axis over a boxplot. The problem is that the point of the line does not correspond to the centrepoint of the boxplot, which makes presentation and interpretation sloppy. Could someone point out where I am going wrong please? #DATA

Dear R-helpers: I am an entry-level R user and have a question related to overlaying a barchart and and a xyplot using latticeExtra. My problem is that when I overlay them I fail to align their x-axes. I show my problem below through an example. #the example data frame is provided below vec <-c(1,5.056656,0.5977967,0.06126587,0.08557778, 2,4.601049,0.5995989,0.05002188,0.11410027,

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

I get strange results when I try to format() an NA character string. > x <- 'sometext' > x[1] <- NA > format(NA, width=32) # displays sensibly, right-justified > format(x,width=32) # displays sensibly, left-justified > format(x,width=33) # displays "" > format(x,width=36) # R exits abnormally with code 5 > version platform i386-pc-mingw32

The help page for library says that: package, help: name or character string giving the name of a package. Yet, I don't seem to be able to use a string variable here. > version _ platform sparc-sun-solaris2.6 arch sparc os solaris2.6 system sparc, solaris2.6 status major 1

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] <-

On a system with IEEE_754 undefined, I run into an bug, when the value of an element of the first argument (e.g., x[0]) of formatReal() is NA: 1. (format.c:235) if (!R_FINITE ..) gives nanflag=1 (!naflag remains 0) 2. (format.c:272..288) *m gets an value of -2147483643 (from the format fiddling, should not matter to us) 3. (format.c:289) because naflag is zero, m does not

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

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:

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 <-
