The function "substitute" seems to fail to make a genuine substitution, although the printed verision seems fine. Here is an example. > m <- substitute(Y <- function(x) FUN(x+1), + list(Y = as.name("y"), FUN = as.name("sin"))) > m y <- function(x) sin(x + 1) > eval(m) > y function(x) FUN(x+1) However the story doesn't end there. The

I'm encountering excruciatingly slow load times for character vectors in R 2.6.0-- up to 30sec for a 15K file that contains a no-attributes character vector of length ~1e4 and object size ~0.5MB. In R 2.5.1, repeated loads of the same set of files are near-instantaneous. The problem is proving tricky to reproduce consistently from scratch, so I have attached the 3 files used in the examples

There's a problem new to R2.4.0 when rbinding an auto-row-named data.frame to a list: > rbind( data.frame( x=1), list( x=2)) Error in attr(value, "row.names") <- rlabs : row names must be 'character' or 'integer', not 'double' Works OK with 2 data.frames or 2 lists.

Hi all I have a plot with lines, one specified as (say) lty=1, using standard line types, and another as (say) my own spec: lty="51". I can't get legend to display both. Toy example: > plot(1~1) > legend("topright", lty=c("51",1), legend=c("My own","Standard")) Error in segments(x1, y1, x2, y2, ...) : invalid line type: must be

Hi, I'm trying to remove/delete a directory usingR. I've tried the following with no success: % Rterm --vanilla > getwd() [1] "C:/Documents and Settings/hb/braju.com.R/aroma.affymetrix/test" > dir.create("foo") > file.info("foo") size isdir mode mtime ctime atime foo 0 TRUE 777 2007-02-28 14:52:10

This is not so much a bug as an infelicity in the code that can easily be fixed. The initialize expression in the quasi family function is, (uniformly for all links and all variance functions): initialize <- expression({ n <- rep.int(1, nobs) mustart <- y + 0.1 * (y == 0) }) This is inappropriate (and often fails) for variance function "mu(1-mu)".

Hi, on Windows XP Pro with R version 2.7.1 Patched (2008-06-27 r46012) the 'Cairo' and the 'EBImage' packages does not play well together. Loading EBImage before Cairo cause the following to happen: # Rterm --vanilla > library(EBImage); > library(Cairo) Error in inDL(x, as.logical(local), as.logical(now), ...) : unable to load shared library

Hi, I've just downloaded the latest R v2.5.0 alpha (2007-04-04 r41043) for WinXP. When I try to install a package R tries to install it to a no-name (empty name) directory (causing error downstream): RCMD INSTALL R.oo installing to '' FYI: Package install perfectly on R v2.4.1 patched, and did so also on earlier R v2.5.0 devel/alpha(?) versions. Current directory is: C:\tmp with

Hi all, I need to run a program (asreml) thousands of times and each time I have to provide a slightly different dataset. Because I have to run asreml under Windows (DOS or scripts) environment, I have trouble to pass a command variable (or pointer variable or %counter in the following example) to R program so at each counter R can generate a different data set for asreml to run. Any

I use 2 packages that both implement a S4 plot method, where one package depends on the other (the bioconductor package globaltest which depends on multtest). When the plot method is used from within the package, it seems the default plot method is used, and an error is generated. When the method is invoked from the console, the plot is created correctly. I have reproduced this with 2 small

Hi, FYI, I just notice that on Windows (but not Linux) it is orders of magnitude (below it's 50x) faster to serialize() and object to a temporary file and then read it back, than to serialize to an object directly. This has for instance impact on how fast digest::digest() can provide a checksum. Example: x <- 1:1e7; t1 <- system.time(raw1 <- serialize(x, connection=NULL));

library() seems to remember the location of a package when I give it a lib.loc, and then use that version thereafter, even if I don't supply lib.loc again. Is there any way I can load different versions of a package in one R session? -- I don't seem to able to simply detach the package and then load a different version from a different library location. $ R [...startup info...] >

Hi all, How can I have a dynamic list for different combinations of grouping factors in the following example? Thanks. dat <- data.frame(x=rnorm(100), a=sample(letters[1:5], replace = T), b=sample(letters[1:5], replace = T), c=sample(letters[1:5], replace = T), d=sample(letters[1:5], replace = T)) ## define grouping

\b is word boundary. But, unexpectedly, strsplit("dia ma", "\\b") splits character by character. > strsplit("dia ma", "\\b") [[1]] [1] "d" "i" "a" " " "m" "a" > strsplit("dia ma", "\\b", perl=TRUE) [[1]] [1] "d" "i" "a" " "

I am the maintainer of a Bioconductor package (affylmGUI) which uses tcltk. It freezes inconsistently on MS Windows, but not Mac or Unix. see details below. After considerable testing I have reduced the problem from a few thousand lines of code to 30 lines! If you paste the following lines of code into an R window: testGUI <- function(){ require(tcltk) MainWindow <-

I run R on MS Windows. In R2.9.0dev, I type ?base to get "R help for package base" to open. I then select ".First" from the list of contents, getting a page headed: "Initialization at Start of an R Session". About half way down there is a sentence: The command-line flag --vanilla implies --no-site-file, --no-init-file, --no-restore and --no-environ. Under
