       You may also be interested in the "psych" package or possibly 
"mvtBinaryEP".  I found these using "sos":


library(sos)
tc <- findFn('tetrachoric correlation') # 26 matches
tcs <- findFn('tetrachoric correlations')#27 matches
tc. <- tc|tcs
summary(tc.) # 35 links in 5 pkgs
tc.


       All but 3 of the 35 links are to "psych", and 2 of the remaining 
3 are to two different copies of "mvtBinaryEP".  You might also Google 
for "tetrachoric correlation".


# OR:
u <- findFn('uniformly distributed correlated data') # 3 matches


       Hope this helps.
       Spencer
