Hi, all,

I'm running a monte carlo simulation with missing data. The data are arranged 
such that there are k columns and n rows over a set number of simulations (set 
to 10 right now so it runs fast while I set everything up). The data are 
integers, numbers 1-7 only (normal distribution). The simulations are set up 
and run without a hitch, including imposing NA missing values at a specified 
prevalence semi-randomly (there are not allowed to be any completely empty 
rows).

I'd like to replace the missing values ("NA") with the mean for the non-missing 
items items *on that row*.  I want to go through all the monte carlo simulation 
runs that I already did (so that I'm using the same data) and replace NA with 
the mean (e.g., if k=5 and a row has values of 3 3 NA 5 5, I want to put a 4 in 
for NA). I also want the imputed mean values to be rounded to the nearest 
integer.

Does anyone have an idea for how I'd set that up? I feel like there's a fairly 
easy way to set up searching out those NAs and replacing the the row mean that 
is not coming to me.

Thanks,
Mike
