-mofd()- doesn't map monthly to annual dates. See -help dates and times-.

I did manage to collapse the data from monthly to annual but in the process lost individual firms. I have used the following commands

gen dm = mofd(date1)
format dm %ty
collapse rp rm, by(dm)

Lets rephrase my question: I want to collapse the panel data by each individual firms. What is the best procedure for me.

I am trying to convert the monthly return of 29 firms into annual means from Jan2000 to May2012. I have tried to use the tscollap command. I get the following results:

tscollap rp rm, to(y)

Converting from M to Y

unknown egen function filter()
r(133);

I just have downloaded the tscollap, It should be most updated. Even if it worked, I don'e know whether tscollap will take care of individual firms identified by id

Alternatively, I can use collapse command, however collaps does not take into consideration the time. I have looked into several posts but could not find a reasonable solution in my particular case.
