Re: [R] Question about the rgroup option in Hmisc latex function

Hi Ista, I think you looking for: n.rgroup? See help(latex). Also, try posting your example in a copy and past form, like: descriptives<-data.frame(n=..., mean=...) etc. The easier it is for others to reproduce your initial results the quicker the problem will be solved. HTH,

[R] maps and lattice

Is it possible to place maps onto lattice plots? With basic plotting you can add a map to a plot library(lattice) long<-c(-69.2, -69.5, -70.1, -70.3) lat<-c(41, 41.5, 43.2, 42.8) plot(long, lat) map('state', c("massachusetts"),add=TRUE) but is it possible with lattice? library(lattice) factor<
