Zitat von "Gerhard Schön, UKE Hamburg" <[EMAIL PROTECTED]>:
> what is the result of: > > df <- data.frame(x = 1:5, y = 1:5) > plot(df, pch = 1:5) It prints different symbols. It seemed, that my pch-settings had an effect, but some symbols were very similar, especially, when a lot of them are plotted at similar places. But I also had the effect, that some symbol numbers didn't print enything, but *after* the loop I used, warnings were printed. Do you know how to plot very small dots? pch=20 makes dots that are too big for my plot. Is there a possibility to have more detailed control on the symbols?
