Change diagonal plots in ggpairs

Question

I'm not able to change the diagonal plots in a ggpair-plot. I would like to change their appearance in general and maybe starting by leaving them blank. This is how I think it should be:

ggpairs(data=df,
             columns=1:3,
             diag = list(discrete = "blank"),
             title="APD pool",
             mapping=ggplot2::aes(colour = Irradiated)
            )

but it ends with a density curve(?!) in the diagonal elements. Due to Robin's comment I tried it with

ggpairs(data=df,
             columns=1:3,
             diag = list(continous = "blank"),
             title="APD pool",
             mapping=ggplot2::aes(colour = Irradiated)
            )

but it doesn't change.

What am I doing wrong? Thank you!

The data are continuous, not discrete. – Robin Gertenbach Apr 26 '18 at 16:24 — Robin Gertenbach, Apr 26 '18 at 16:24
Thank you but this didn't change anything – Ben Apr 27 '18 at 06:29 — Ben, Apr 27 '18 at 06:29
It should be continuous, not continous :) – Robin Gertenbach Apr 27 '18 at 08:20 — Robin Gertenbach, Apr 27 '18 at 08:20

You spelled continuous wrongly. Your code spelt it "continous" instead.

When you use diag, you have to pass in a list that may only contain the variables continuous, discrete, and na. When you assign a value to continuous, it can only be exactly one of

'densityDiag'
'barDiag'
'blankDiag'

So instead of diag = list(continous = "blank") you want to have diag = list(continuous = "blankDiag") instead. That would do the trick:
