R help - Jul 2012 - "metafor" package, proportions: single groups wrt to a categorical dependent variable

Dear all, I am using R version 2.15.0 and 'metafor' package version
1.6-0. Can this version of the package handle proportions from a  categorical
dependent variable for single studies?If so how do I set up my dataframe for the
raw data from different studies? Also how do I give inputs, specially xi, mi (or
ni) to the function escalc()? Thanks,Dushanthi

You do not give us very much to go on here. When you say your outcome 
is proportions do you mean your outcome has more than two values and 
you are generating (or have been provided with) several proportions 
for each study or do you mean it is a binary variable? If the latter 
do you in fact have the numerators and denominators or just the 
proportion? It would also help if you showed us the code you have 
tried and the error message you got (if any) or told us the 
discrepancy between the output you obtained and that which you expected.
