Hi, In man page for duplicated: Value: ?duplicated()?: For a vector input, a logical vector of the same length as ?x?. For a data frame, a logical vector with one element for each row. For a matrix or array, a logical array with the same dimensions and dimnames. When 'x' is a matrix or array, the returned value is NOT a logical array: > m <-

Dear list, Is there an exact formula / safe rule of thumb that allows one to express the value of --max-ppsize as a function of the value of getOption("expressions") ? ?options tells "If you increase it [the expressions option], you may also want to start R with a larger protection stack". Motivation is to determine stack size of a Java vm used to launch R with a given

Hi, for simply for troubleshooting purposes (e.g. making sure that --max-ppsize=N) is set, is there a way to query the pointer protection stack size from R? I tried to grep the source code and couldn't find anything, so I expect the answer is no. Thxs, Henrik

Hi, The cleanup_pkg() function defined the big tools:::.build_packages() function in tools/R/build.R is currently broken. When Makefiles are used cleanup_pkg() doesn't clean anything because of the way system2() is called. For example, the call to Ssystem() on line 304 (Ssystem is a silent version of system2) is basically trying to do this: >

Hi, The following code produces different kinds of problems depending on which platform you run it: x <- as.list(1:200000) names(x) <- paste("A", 1:200000, sep="") e <- list2env(x) Timeout on Linux, crash on Mac and Windows, with R 2.12.0 and current R devel. The "multi-assign" mode (i.e. when the 'envir' arg is supplied) doesn't seem

I get this (with R-2.12 and R-2.13, didn't try with earlier versions): > max(c(NaN, NA)) [1] NA > max(c(NA, NaN)) [1] NaN I get the same thing with min(). The fact that the result of 'max(x)' or 'min(x)' depends on the order of the elements in 'x' is surprising. It also seems to contradict the man page: By definition the min/max of a numeric vector

Hi, 'R CMD build' (with R 2.12.0 RC) fails to clean the src/ folder on Windows: D:\biocbld\bbs-2.7-bioc>ls meat/BUS/src BUS.cpp BUS.h D:\biocbld\bbs-2.7-bioc>R\bin\R CMD build meat\BUS * checking for file 'meat\BUS/DESCRIPTION' ...

Hi, According to its man page substring() "expands (its) arguments cyclically to the length of the longest _provided_ none are of zero length". So, as expected, I get an error here: > substring("abcd", first=2L, last=integer(0)) Error in substring("abcd", first = 2L, last = integer(0)) : invalid substring argument(s) But I don't get one here:

Hi, Is the following command used to increase the memory or any other command when a background R job is run?

Hi, When 'x' is a vector of doubles, it's not clear how 'factor(x)' compares its values in order to determine the levels. For example, here all the values in 'x' are "conceptually" the same: x <- c(11/3, 2/3 + 4/3 + 5/3, 50 + 11/3 - 50, 7.00001 - 1000003/300000) However, due to machine rounding errors, they are not

Hi, On both Unix and Windows there is a mechanism to add variables to the environment when R is started. I noticed that, on Unix, this mechanism is not used when R is started normally at the command line but only when it's started using the 'R CMD' syntax. One problem with this is some lack of consistent cross-platform behaviour. For example: On Linux: $ echo $TEXINPUTS $

Hi, Already reported here: https://stat.ethz.ch/pipermail/r-devel/2010-September/058636.html but it doesn't seem to be related (at least not in an obvious way) to the problems described in that previous thread. So the problem is that, with recent versions of R 2.12 (i.e. current R-alpha but I've observed this with R-devel for at least 2-3 months now), 'R CMD build

G'day all, In Chapter 1.4 (Writing package vignettes) the Writing R Extensions manual states: By default @code{R CMD build} will run @code{Sweave} on all Sweave vignette source files in @file{vignettes}. If @file{Makefile} is found in the vignette source directory, then @code{R CMD build} will try to run @command{make} after the @code{Sweave} runs, otherwise @code{texi2pdf} is run on

Hi, Today we've seen the following problem with the R-2.12 that we use for our Windows builds: > installed.packages() Error: subscript out of bounds After some investigation we discovered that the cause of this failure was that 1 of the 890 packages currently installed on the machine (Windows Server 2003 R2) had its DESCRIPTION file empty:

Dear All, at the moment I am using R for calculations of large databases. Unfortunately, R only manages to complete certain operations at some times, and not at others. I usually get the error message "cannot allocate vector of size XX" I am using the 64-bit version with Windows 7. While my computer has 8 RAM, I do have a feeling that R cannot use all of it. Searching online, I

Hi, I just realized that a named empty list is displayed the same way as an empty list: > list(aa=2:5)[0] list() > list() list() For empty atomic vectors, the print method makes the difference: > c(aa=3L)[0] named integer(0) > integer(0) integer(0) Maybe lists could do that too?
