Hi,
In the documentarion of sort() it reads (Arguments section):
"...: arguments to be passed to or from methods or (for the default

should it be 'sort.int' instead of 'sim.int'?

Simple solution provide by Prof. Ripley is to modify the relevant code as
follows (he posted in the R-development group):

as.integer(n),
as.integer(length(x)), as.double(d), x, as.double(h),
u = double(1))$u
