As it seems that everyone's wishes for getting bugs fixed are granted
right away, here is something that I alread mentioned once.
* It seems that S allows recycling when subscripting with logicals, but
R does not. E.g.,
R> x <- 1:5
R> x
[1] 1 2 3 4 5
R> i <- c(F, T)
R> x[i]
Error: invalid subscript type
R>
In S, this is treated as x[rep(i, length = length(x))].
* It also seems that S does not worry about excluding subscripts which
are out of bounds. In the above, x[-6] would give x, but in R
R> x[-6]
Error: subscript out of bounds
