[R] tables with row sorted numerically although factors

[Rui Barradas]

Hello,

First of all, there's no need for data.frame(cbind(...)). data.frame() 
only will do the job, and it's less error prone.

As for the question, since the column Nodes is to become a factor, why 
use as.character()? Without it the problem is solved:


data      <- data.frame(Nodes,Values)
data$Nodes<- factor(data$Nodes) # necessary to get factors for tabular

tabular(Nodes  ~ Values*mean, data=data)


Hope this helps,

Rui Barradas
