Hello,

I am trying the ifelse command for imputing a variable based on a
conditional statement, but the NAs do not transform.  The code I am trying
is:

ifelse (x==1, y=="NO", y=="YES").  However, the number of NAs remains the
same after the attempt.   I would like to turn all Y (NAs included) into a
"YES" or a "NO".

Thanks in advance,

Ana
