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!
