Olá,
Please keep this in the list, I'm cc-ing r-help at r-project.org. And yes,
I am Portuguese but R-Help is a mailing list in the English language.
As for your new question, I believe that you should start a new thread.
This is completely different from the question on computing mean and sd.
Ask a new question.
Font "arial" is a Microsoft font and as far as I know is not supported
by R. And 'size' is not a graphical parameter. To see the font families
supported by R see the help page ?par.
Note that width and height are arguments to function ?windows not to
function plot.
windows(width = 6, height = 5) # open a new window
plot(1:10, main = "Teste", family = "serif")
