Hi
A simple computation results in integer overflow:
These are the relevant vectors:
> sum(cur.obs)
[1] 110231
> colfreq
other past perfect present progressive
14845 1222 4776 101347 2863
> sum(colfreq)
[1] 125053
Now ...
# this works ...
> sum(cur.obs)*(colfreq/sum(colfreq)) # note: brackets around the division
other past perfect present progressive
13085.485 1077.162 4209.921 89334.771 2523.661
# and this doesn't ...
> sum(cur.obs)*colfreq/sum(colfreq) # note: no brackets around the division
other past perfect present progressive
13085.485 1077.162 4209.921 2523.661
Warning message:
In sum(cur.obs) * colfreq : NAs produced by integer overflow
I saw this was reported for R 2.3.0 and 2.6.0 before, but I don't know whether
it ever got dealt with. Here's my version information:
