[R] all (y,x) data in one plot

[Petr Pikal]

Hi

yesterday was answered similar list question (do.call is your friend)

lll<- list(data.frame(a=1:10,b=rnorm(10)), 
data.frame(a=1:9,b=rnorm(9)+5))
mat <- sapply(lll, dim)
plot(do.call("rbind",lll), pch=rep(1:dim(mat)[2], 
times=as.numeric(mat[1,])))
