I'd been using error() (from R.h) to return to R if there is an error, but then I realized that this might be not safe as supposedly error() doesn't throw an exception and therefore some destructors do not get called and some memory may leak. Here is a simple example extern "C" void foo() { string

At present the example data sets in R libraries are to be given as expressions that can be read directly into R. For example, the acid.R file in the main library looks like acid <- data.frame( carb = c(0.1, 0.3, 0.5, 0.6, 0.7, 0.9), optden = c(0.086, 0.269, 0.446, 0.538, 0.626, 0.782), row.names = paste(1:6)) This is great when you have only a few observations. I have one example data
