similar to: Parallel R CMD check?

In pvec(list(1, 2), FUN, mc.cores=2) FUN sees integer() arguments whereas pvec(list(1, 2, 3), FUN, mc.cores=2) FUN sees list() arguments; the latter seems consistent with pvec's description. This came up in a complicated Bioconductor thread about generics and parallel evaluation https://stat.ethz.ch/pipermail/bioc-devel/2012-October/003745.html One relevant point is that a

Hi Gabor, I just used your R code below and the code worked properly without any error messages. Attached is the output graph, which may be the one you expected. library("Rgraphviz") set.seed(123) V <- letters[1:10] M <- 1:4 g1 <- randomGraph(V, M, 0.2) g1 plot(g1) Thanks.

A package uses VignetteEngine: knitr; the package itself does not Suggests: knitr, but it Suggests: BiocStyle which in turn Suggests: knitr. Nonetheless, R CMD check fails indicating that a package required for checking is not declared. Is it really the intention that the original package duplicate Suggests: knitr? This is only with a recent R. In detail, with $ Rdev --version|head -3 R Under

Hi Martin, It is really a 'PATH' problem. After adding C:\Program Files\Graphviz2.20\bin to the 'PATH' environment variable, the Rgraphviz package can be loaded without any error messages. Sorry that I ONLY set my 'PATH' environment variable correctly for R but not for Graphviz. Thank you and Duncan so much for your great help. Howard On Tue Mar 30 18:12:54

A post on the Bioconductor mailing list https://stat.ethz.ch/pipermail/bioconductor/2009-May/027700.html suggests that install.packages now references .Rprofile (?), whereas in R-2-8 it did not. Is this intentional? The example is, in .Rprofile library(utils) install.packages("Biobase", repos="http://bioconductor.org/packages/2.4/bioc") then

This bug appears intermittently in R CMD check when reference classes have finalize methods. The problem is that garbage collection can be run after the methods package is no longer available. It affects (periodically) the Bioconductor AnnotationDbi package as well as packages that contain Rcpp classes. To reproduce: library(methods) a = setRefClass("A",

as.factor / as.ordered is not written as a generic. This differs from as.numeric, as.matrix, and other as.*. The following seems to address this and does not break make check-all. FWIW, the patch is against r55563, because with r55564 I see /home/mtmorgan/src/R-devel/src/main/dounzip.c:75:15: error: storage size of ?dt? isn?t known /home/mtmorgan/src/R-devel/src/main/dounzip.c:88:5: warning:
