In R all things are possible:
rcb <- function (...) {
# rcb <--> ``ragged cbind''
xxx <- list(...)
n <- max(unlist(lapply(xxx,function(x){ifelse(is.matrix(x),nrow(x),
length(x))})))
yyy <- lapply(xxx,function(x,n){if(is.matrix(x))
rbind(x,matrix(NA,ncol=ncol(x),nrow=n))
else c(x,rep(NA,n-length(x)))},n=n)
do.call("cbind",yyy)
}
cheers,
