The trouble is that in my real data set each group does not always have an observation that choose each response. This results in some of the "rows" returned from prop.table() to be shorter than others so I get: Warning message: In function (..., deparse.level = 1) : number of columns of result is not a multiple of vector length (arg 8) Is there a way to tell rbind() or do.call() to treat missing values as zero or make prop.table() include the zero proportions?
