[R] Executing an R script and show the plots.

[Rui Barradas]

Hello,

Have you tried

source("script.r", print.eval = TRUE)

?

Also, you should print() the graph explicitly:


library(ggplot2)
data(midwest, package = "ggplot2")

g <- ggplot(midwest, aes(area, poptotal)) + geom_point()
print(g)


Hope this helps,

Rui Barradas
