just that it does not use vectorized operations.
The package RJSONIO
http://www.omegahat.org/RJSONIO
can be used as a drop-in replacement for rjson and was written to be
faster (by using vectorized operations) and

I am trying to specify a multinomial logit model using the multinom function
from the nnet package. Now I add another independent variable and it halves the
AIC as given by summary(multinom()). But when I call Anova(multinom()) from the
car package, it tells me that this added variable is

i had intstalled R in my home directory
and i can run the new install R from /path_of_my_home/R/bin/R
