ggbivariate only working with numerical outcome variable and output looks weird

[theanita1]

Hi there
Apologies if this issue has been previously addressed but I couldn't see it previously being brought up

I can only get ggbivariate to work if the outcome variable is a number - e.g. 0/1, 1/2 and then the output doesn't look anything like the examples you've got on the vingettes

Here's what I mean

df<- pengiuns
GGally:: ggbivariate(df, "sex")

If I run this without first transforming the sex variable, I get this error:

But, if I transform the outcome variable

df<- df %>% mutate(sex = factor(sex, 
                                levels = c("male", "female"), 
                                labels = c(1, 0)) %>%
                     as.character() %>% 
                     as.numeric())

then I get this output:

Which technically the function runs, but doesn't look anything like what you have as your examples

Hopefully it's an easy fix, maybe something running on my RStudio (4.5.0) or a dependency that has been masked

Thanks

Thank you for the reprex! I have ran a similar one below.

Unfortunately, I can not replicate your observed behavior. Please be sure that you have the latest versions of GGally, ggplot2, and ggstats. Please also double check that your data set hasn't been compromised (I used palmerpenguins::penguins where you had pengiuns).
