Ricardo - how to make those crosstables for subsets?

CrossTable(nsqip.data, subset=diagnosis=='appendicitis')(numage10yrcatstart39, postopdeath, chisq=TRUE, missing.include=TRUE, format="SAS", prop.r=FALSE) Error in CrossTable(nsqip.data, subset = diagnosis == "appendicitis") : all entries of x must be nonnegative and finite In addition: There were 37 warnings (use warnings() to see them)

CrossTable(numage10yrcatstart39 & diagnosis=='appendicitis', postopdeath & diagnosis=='appendicitis', chisq=TRUE, missing.include=TRUE, format="SAS", prop.r=FALSE)
