Sir,

Its wonderful to start using this software R. I am making full efforts to
learn it on my own with the help of the free online manuals available. I am
using epicalc package in R. I have a dataset where i want to apply
conditions like... if var1 is yes or 1, assign 1 to it or else 0. Can you
help me with this problem?

Thanking you,
