Changing aesthetics of the correlation plot about correlation HOT 2 OPEN

Hi Mark,

You can customize the legend and change the orientation by overwriting some ggplot specifications:

library(ggplot2)
#> Warning: package 'ggplot2' was built under R version 4.2.2
library(correlation)

mtcars |> 
  correlation() |> 
  summary() |> 
  plot() +
  scale_fill_gradient2(low = "purple", high="green") +
  scale_y_discrete(limits = rev)
#> Scale for fill is already present.
#> Adding another scale for fill, which will replace the existing scale.
#> Scale for y is already present.
#> Adding another scale for y, which will replace the existing scale.

Hope that helps!

Brilliant, this is exactly what I was looking for. The next question is: I then plotted the correlation for some of the relationships using:
plot(cor_test(ROM_PF_left, "PF_LLLI","PF_LLSJ")) +
theme_bw()
I am trying to increase the marker size and color, but nothing seems to alter the marker size. I tried using "cex=3" but this was not effective. Are there any suggestions?
I also tried creating another layer using "geom_point", which works, but if I change the alpha level, the dots from the original layer are visible.
