[R] How to visualize this df

[PIKAL Petr]

Hi

you still should post a snippet of your data to help others better understand.

It should be something like
p<- ggplot(dat, aes(x=Protocol, y=NRuns, fill=Speed))
p+geom_bar(stat="identity")

But as you have 132 levels of protocol unless you have big big monitor you will have problems to display all protocols properly.

You could try to use points but it probably does not help much.

You could try similar approach as here
http://www.phaget4.org/R/image_matrix.html

or you could try to tweek your table to fit image function.

Cheers
Petr
