Handy function for HSV-scale-izing real-valued data.
hsv.scale <- function (var, hmin, hmax=hmin, smin=1, smax=smin, vmin=1, vmax=vmin,
na.col=rgb(0.75, 0.75, 0.75))
{
var.min <- min(var, na.rm=TRUE)
var.max <- max(var, na.rm=TRUE)
h.f <- approxfun(c(var.min, var.max), c(hmin, hmax))
s.f <- approxfun(c(var.min, var.max), c(smin, smax))
v.f <- approxfun(c(var.min, var.max), c(vmin, vmax))
tmp <- var

Javascript style "immediately invoked function expressions" plus on.exit for scope guards in R. Cleanup actions get carried out regardless of clean or error exit from block.
(function() {
pdf("example.pdf")
on.exit(dev.off())
plot(some.data)
})()

Dinking around with building windows DLLs with MinGW again. And figured out where the [[gnu::stdcall]] goes.
g++ -std=c++11 -Wall -Wextra -c dlltest.cpp
g++ -shared -static-libgcc -static-libstdc++ -o dlltest.dll dlltest.o -Wl,--add-stdcall-alias
