Hi Abdelkrim, you may have a look into Rammer W and Seidl R (2019) Harnessing Deep Learning in Ecology: An Example Predicting Bark Beetle Outbreaks. Front. Plant Sci. 10:1327. doi: 10.3389/fpls.2019.01327 They used the H2O...
Thanks Olaf, Thanks Daniel, Problem solved. The typo was only in the mail. But I funneld the -lrt flag via the R CMD INSTALL mechanics to the compiler instead of to the linker. Setting PKG_LIBS=-lrt in Makevars did...
Hi Ivan, Thanks for reporting this bug. >Error in as.integer.hi(x, ...) : object 'ret' not found debug(as.integer.hi) and calling again shows that the return value 'integer()' was not assigned to 'ret'. This is fixed now in...
Dear all, what is the proper way to make the assignment operator generic and define methods depending on the class of the assigned value? Best regards Jens Oehlschl?gel P.S. I vaguely remember that this was possible in S...

I can compile a package under clang++ with -stdlib=libstdc++, but with -stdlib=libc++ I get " In file included from /home/jo/R/x86_64-pc-linux-gnu-library/4.0/Rcpp/include/Rcpp/r/headers.h:67: /home/jo...
Code-named R+Team, our commercially supported R group is looking for beta testers for R+ on Solaris and R+ on Linux. We'd love to get your feedback for our R+Professional version that has additional funcationalities for enterprise...
Peter, ff objects are not allowed as subscripts to ff objects. You can take several routes 1) use bit objects instead of logical or ff logical. This is fast and takes factor 32 less RAM than logicals (BTW bit objects...

Not only changing mode or length (i.e. structure) of the original object results in converting an .Alias into a real copy, as the following examples show: > x <- 1:9 > y <- .Alias(x[9]) > y[1] [1] 9 > y[1...

Dear all, ? I don't know if you consider this a bug or feature, but it breaks reasonable code: 'unlist' and 'sapply' convert 'ordered' to 'factor' even if all levels are equal. Here is a simple example: o <- ordered(letters...
