Prof Brian, Thanks for the reply. My mistake its "clRes" in place of "result"
> chrcomb <- sapply(clRes, function(x) rbind(x)) Error in rbind(x) : no method for coercing this S4 class to a vector I think what you mentioned about the package forgetting to import an S4 generic for rbind seems the logical explanation of this problem.
