Dear all,

Tried to add column margins of a sample data. The data was extracted from
xtable library,

it gives erroro the below,

appreciated if you have any idea.

Bests,


head(iris)
irisk<-head(iris)
table<-xtable(irisk,digits=2)
table2 <- xtable(addmargins(as.matrix(irisk),
2), digits = 0)
Error in FUN(newX[, i], ...) : invalid 'type' (character) of argument
