JOSS review: increase size of 'X' in ggcorrmat?

[kevinrue]

More of a question than a suggestion:

How about increasing the 'X' that marks non-significant correlations?

Right now, it's actually a bit difficult to spot the X's because they're about the same size at the correlation value.

I'm wondering whether making the 'X' bigger would achieve two benefits:

• easier to spot the X's
• easier to read the non-significant correlation values (for what they're worth ...) that are hidden behind those X's

Thanks for the suggestion. This is a good point. Here is the changed behavior:

# for reproducibility
set.seed(123)
library(ggstatsplot)

ggcorrmat(
  data = ggplot2::msleep,
  colors = c("#B2182B", "white", "#4D4D4D"),
  title = "Correlalogram for mammals sleep dataset",
  subtitle = "sleep units: hours; weight units: kilograms"
)

Brilliant! I think it looks great now. I hope you agree as the developer, but as a user I find it both clearer to spot the X's and more readable (the numbers behind the X's).
