Dear R-Helpers, I have a large data matrix, which contains missing data. The matrix looks something like this: 1) X X X X X X NA NA NA 2) NA NA NA NA X X X X X 3) NA NA X X X X NA NA NA 4) X X X X X X X X X 5) X X NA NA X NA NA NA NA and so on. Notice that the first row starts with complete data but ends with missing. The second row starts with missing, but the rest is

LLVMers, The 2.5 pre-release is available for testing: http://llvm.org/prereleases/2.5/ If you have time, I'd appreciate anyone who can help test the release. Please do the following: 1) Download/compile llvm source, and either compile llvm-gcc source or use llvm-gcc binary (please compile llvm-gcc with fortran if you can). 2) Run make check, send me the testrun.log 3) Run "make

Hi everyone, Some of you probably received the following thread from the Rcpp-devel mailing list: http://lists.r-forge.r-project.org/pipermail/rcpp-devel/2018-August/010072.html Summing up, the issue described is the following: pkg1 provides type1 in pkg1.so building on some headers. pkg2 links to pkg1 (BTW, LinkingTo is actually misleading, because it doesn't really link to it), i.e.,

Hi, I found the following issue in r-devel (2019-01-02 r75945): `foo<-` <- function(x, value) { bar(x) <- value * x x } `bar<-` <- function(x, value) { stopifnot(all(value / x == 1)) x + value } `foo<-` <- compiler::cmpfun(`foo<-`) `bar<-` <- compiler::cmpfun(`bar<-`) x <- c(2, 2) foo(x) <- 1 x # should be c(4, 4) #> [1] 3 3 If the functions
