Hi,
I'm trying to make a boxplot with the data at the end of the message, and when I
try to execute the command
>boxplot(Diatoms) (or for any other field instead of "Diatoms")
I get the following error message:
Error in oldClass(stats) <- cl : adding class "factor" to an invalid object
Any advice would be much appreciated.
Thanks a lot,
Miriam
