Hi Enrico,
Yes, you were right, I just wanted to draw white vertical lines and with
your command it's much simpler. Thanks a lot!

Hi Eik,
I learned a lot from your tips about sapply and Vectorize!
I had only used apply, lapply and mapply but not yet sapply.
I find the Vectorize function very fascinating: being able to change a
function - this is something I hadn't come accross yet.
By checking out the command "invisible" I also learned a new command.
Thank you very much!

Marion


Hi Marion,

is all you want the white vertical lines? Then try

abline(v = seq(10, 90, by = 10), col = "white")

instead of your axis commands.

Enrico
