Hi, > Can you post a reproducible example that leads to this error?
myplot <- function(x) { plot(x) } efaApp <- function(data, ...) { playwith (myplot(data[,8:9]), click.mode = "Brush", ) } efaApp(as.data.frame(Boston)) My plot routines even return invisibly a list itself. >> Under linux my R program simply continues, but under Windows it stops. I just saw that under Windows my program continues as well, just the GTK+ window was minimized.
