After the following commands (issued just after starting R) set.seed(1) n <- 600 x <- rnorm(n) y <- rnorm(n) aFactor <- factor(rep(1:5, length = n)) plot(x, y, col = aFactor) R prints *** caught segfault *** address 0x10, cause 'memory not mapped' Segmentation fault and dies. (Yes, I know that using a factor as `col' is wrong; I discovered this by a mistake. :-) Substituting "aFactor &lt...
