...data (see http://www.xycoon.com/gini_mean_difference.htm for a related formula). Unsurprisingly, the function is slow (compared to sd or mad) for long vectors. I wonder if there's a way to make the function faster, short of creating an external C function. Thanks very much for your advice. gmd <- function(x, w) { # x=data vector, w=weights vector n <- length(x) tmp <- 0 for (i in 1:n) { for (j in 1:n) { tmp <- tmp + w[i]*abs(x[i]-x[j]) } } retval <- 0.5*sqrt(pi)*tmp/((n-1)*sum(w)) } gmd(rnorm(100)) Regards, Andrew C.

Hi Mr Anvin, after downloading the Freedos bootable cd, which now uses your projects (ISOLINUX & MEMDISK) instead of Bart Lagerweij's DISKEMU (www.nu2.nu), I contacted the creator of the freedos cdrom. I was interested in how he did make that cd bootable. Now I understand it a bit. As I'm a MS Windows user, I had to figure some things out. However, upon booting I get a beautiful

I was hit by ugly crashes of R, when I tried to read big data sets ("volcano"). So I looked into the code and found the following in character.c (triggered by substr()): I assume that the helper function AllocBuffer() shall facilitate an economic memory management. But the use of realloc() in the else-branch does not conform to ANSI and may hit you with certain compilers. When called
