subset data frame by variable with missing value
Hello,
I have a variable in a data frame that contains NA values. I just want to
subset so that I get the obs where that variable is missing.
In SAS I would do:
data missing;
set test;
if myvalue=' ';
run;
How can I perform this simple task in R?
Thanks in advance for your help.
