Adjustment of the correlation data labeling content in the upper right corner of ggpairs

When I use the ggpairs function in ggally, the result will always contain an “overall” extreme result of the data: corr:***. This is not always appropriate (needed) after analyzing the data grouping. I recently read an article with the same situation, and all I can think of at the moment is to export the PDF file and then process it. Does anyone have a more straightforward approach?

This figure comes from:https://www.nature.com/articles/s41559-023-02253-z

For comparison, the official package example has a 'corr:**' result after the grouping：

Here is one (hacky??) option which removes the title aka the overall correlation using title_args = list(x = NA, na.rm = TRUE), then fixes the position of the group correlations using the group_args= argument of ggally_cor.

Using a minimal reprex based on iris:

library(ggplot2)
library(GGally)
#> Registered S3 method overwritten by 'GGally':
#>   method from   
#>   +.gg   ggplot2

dat <- iris[c(1:3, 5)]
names(dat) <- c(paste0("tars", 1:3), "Species")

ggpairs(
  data = dat,
  mapping = aes(color = Species),
  columns = 1:3,
  upper = list(continuous = wrap(
    ggally_cor,
    group_args = list(
      y = I(seq(.2, .8, length.out = length(unique(dat$Species))))
    ),
    title_args = list(x = NA, na.rm = TRUE)
  ))
)
