Pb with agrep()

Happy new year everybody,


I'm getting the following while trying to use the agrep() function:

 > pattern <- "XXX"
 > subject <- c("oooooo", "oooXooo", "oooXXooo", "oooXXXooo")
 > max <- list(ins=0, del=0, sub=0) # I want exact matches only
 > agrep(pattern, subject, max=max)
[1] 4

OK

 > max$sub <- 1 # One allowed substitution
 > agrep(pattern, subject, max=max)
[1] 3 4

OK

 > max$sub <- 2 # Two allowed substitutions
 > agrep(pattern, subject, max=max)
[1] 3 4

Wrong!
