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?
Thank you in advance

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, Rolf Turner -- Technical Editor ANZJS Department of Statistics University of Auckland Phone: +64-9-373-7599 ext. 88276
I note that you have "Year-month" (capital 'Y') and "year-month" in your code; case matters in R. Otherwise, Rolf's advice applies.

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.

Subject: [R] if and
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?
Thank you in advance
