Dear all, As of the current R alpha release, I'm seeing timezone-related warnings on installing any package (including the recommended ones), which I haven't seen before. For example, [~/Documents/Source/R-alpha]$ bin/R CMD INSTALL ~/git/tractor/lib/reportr * installing to library '/Users/jon/Documents/Source/R-alpha/library' * installing *source* package 'reportr' ... Warning in as.POSIXlt.POSIXct(x, tz) : unknown timezone 'Europe/London' Warning in as.POSIXlt.POSIXct(x, tz) : unknown timezone 'GMT' Warning in as.POSIX...

...ighbours. Operations such as erode and dilate are provided for 2D data by the EBImage Bioconductor package, but mmand can be used for higher (and lower!) dimensional data, can produce and apply anisotropic kernels, and does not have external dependencies--except for the small, pure R package "reportr" (also on CRAN), which is used for message reporting. Owing to its more general, dimensionality-independent implementation, mmand is a little slower than EBImage; but due to various performance optimisations, run time is still very reasonable. For example: > x <- EBImage::readImage(sys...
