Anyone know a quick way to color one bar of a histogram? I want to mark the bar in which the most recent observation falls. So, for instance: x <- rnorm(100) latest.ob <- x[100] hist(x) ## how do I...

I have a package that takes about 20 minutes to compile which tends to prolong the compile/test/compile cycle. Does anyone know how to get R CMD check or R CMD INSTALL to use parallel make? I looked at...

I just reviewed the Rcpp documentation. I see plenty of cfunction/cxxfunction examples, but I'm curious whether one can provide a class definition inline in an R script and then initialize an instance of the class and call a...
