[R] how to change the y-axis to logarithmic in a barplot ggplot

[Maria Lathouri]

Dear Bert, 

Thank you very much for the tip. The reason that I took the initiative to write here is because I receive here as well questions about ggplot. Next time I will use the ggplot help.

Maria,

ggplot is part of the Posit -- formerly RStudio -- assortment of contributed packages. They have their own support site here , which you *may* find useful for such questions, also. Though ggplot queries *are* frequently posted and answered on R-Help.

Cheers,
Bert
