The documentation of stripchart() says that "NA's are allowed in
the data."  I think this would imply that

stripchart(nprob[cancer==4] ~ probtype[cancer==4],meth="stack")

should work even if nprob has a missing datum in the relevant range.
I get the following error message:

Error in xy.coords(x, y) : x and y lengths differ
In addition: Warning message: 
longer object length
is not a multiple of shorter object length in: y + (unlist(xo, use.names =
FALSE) - 1) * offset * csize 

The following works.  There was one missing datum.

stripchart(nprob[cancer==4 & !is.na(nprob)] ~ probtype[cancer==4 &
!is.na(nprob)],meth="stack")

So, either the behavior or the documentation appears to need changing.
I would prefer to change the behavior so it matches the documentation.
