Hello!
I would like to do some tables for several variables and I would like to write
a loop that does the table for each variable. I should also point out that my
data set has several missing observations and sometimes the observations that
are missing are not the same for all my variables.
What I would like to do:
table(StoreData$CompanyID,
!is.na(StoreData$P2))
table(StoreData$CompanyID,
!is.na(StoreData$P5))
If I run the above code, I get:
> table(StoreData$CompanyID,
+ !is.na(StoreData$P2))
FALSE TRUE
2 940 0
3 0 323
4 288 0
5 306 0
> table(StoreData$CompanyID,
+ !is.na(StoreData$P5))
FALSE TRUE
2 940 0
3 0 323
4 288 0
5 306 0
Here's the loop that I wrote, which does not work:
angus <- c(2,5)
for(i in angus) {
cut <- paste("StoreData$P",i, sep="")
table(StoreData$CompanyID, !is.na(cut))
}
When I run the above, I get the following error message:
Error in table(StoreData$CompanyID, !is.na(cut)) :
all arguments must have the same length
> source(.trPaths[5], echo=TRUE, max.deparse.length=150)
Any help is greatly appreciated!
