Currently I have  about  six or more  scripts that do the same job.  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?

Uh, yes.  Get the syntax right.  Use R, when you are using R.

Looking at ?Syntax and ?Logic might help you a bit.

Other than that, there's not much that one can say without seeing a
reproducible example.  And if you sat down and wrote out a *reproducible
example*, using correct R syntax, you probably wouldn't need any assistance
from R-help.

Have you read any of the readily available R tutorials?  If not do so. If
so, read them again and actually take note of what they say!

cheers,
