Hi everyone, I am trying to write STATA codes in R. It is actually a very small puzzle, I guess. My original variable generation in STATA looks like this:
gen Var=1 if (x1
In R the integer division 1%/%2 gives 0, i.e. 1%/%2 == 0 gives TRUE, so why don't you simply use
Var
Hi,
I do not know STATA language. If you explain the STATA code, those of us who know R could more easily help...
To what value is Var set to if the if condition is FALSE? What is the meaning of x4==1/2 in STATA?
Hi Rajan,
I have the same doubt about your question that Pedro raised. I have never used Stata but isn’t "/" an arithmetic operator for division? So in your Stata code that reads x3==1/2, are you not testing if x3=0.5. While in the R code (x3==1|x3==2) is testing if x3 is either equal to 1 or 2?
So, if you are trying to test if x3 (also for x4 and x5) is either equal to 1 or 2 your Stata code should also read x3==1|x3==2, as you have used in the R code.
# Initialise the variable
myVAR = NA
# Build the if-else-statement (Assuming the variables x1,...,x6 have values)
if( x1 < 3 | x2 == 1 | x3 == 1/2 | x4 == 1/2 | x5 == 1/2 | x6 == 1 ){
myVar = 1
} else {
myVar = NA
}
# Display the value of the variable
print(myVar)
Note that I wrote out the entire if-else-statement. However above we assign 'NA' as the default value and hence we actually don't need the else-part.

Thank you all for your responses. I think I didn't give enough info while I asked the question. 1/2 meant integer division. I got the solution now: through the use of x%/%y operator in R. So, my code looks like:
var
In R the integer division 1%/%2 gives 0, i.e. 1%/%2 == 0 gives TRUE, so why don't you simply use
Var
@Veli-Matti Taavitsainen- Thanks!!! That is a pretty good explanation.
