This is not a reproducible example. You did not even show us one of the scripts that apparently did work. None of your if() statements contains a logical expression. You should read "An Introduction to R" and probably other tutorials on R.

I thought it might be possible and more efficient to use one script by using IF ELSE statements. Here is an example but this will be expandable for several countries ans year-months Year-month = FEB2015, FEB2012, Feb2010 country = USA, CAN.MEX First I want to do if country = USA and year-month = FEB2015, FEB2012 do the statements second if country = CAN and year-month =Feb2010 do the statements if(country="USA" & year-month = "FEB2015" | "FEB2012" ){ statemnt1 . statemnt10 } else if (country="USA" & year-month ="FEB2015") { statemnt1 . statemnt10 } else { statemnt1 . statemnt10 } The above script did not work. is there a different ways of doing it? Thank you in advance .
