[Rd] Compatibility of external C code across platforms

A package I have written makes considerable use of external C code. There appear to be no problems building a Windows binary with the GNU C compiler, but now I would like to make the package available for other platforms. A stringent check of the code with the gcc options '-Wall -pedantic' fla

Further to my previous message, I just dug this in lattice/R/layout.R : rearrangeUnit <- function(x, pos, u) { lx <- length(x) if (lx == 1) u else if (pos == 1) unit.c(u, x[(pos+1):lx]) else if (pos == lx) unit.c(x[1:(pos-1)], u) else unit.c(x[1

It seems that there are several folks Out There with an itch to scratch with respect to difftimes. http://article.gmane.org/gmane.comp.lang.r.devel/19223/match=difftime http://article.gmane.org/gmane.comp.lang.r.devel/18441/match=difftime http://article.gmane.org/gmane.comp.lang.r.devel/10882/m

Hello, Is there such thing as a build time dependency between packages : package B needs package A so that it can build, but once built it lives without it. For example depending on the ant package to compile java code, or depend on roxygen to roxygenize the code, ... Adding roxygen to Dep
