transKeepSign argument of `corrplot()` documentation is unclear

[adcascone]

Hello,

On page 14 of the reference manual for corrplot v0.95 (dated October 14, 2024), the 'NOTE:' listed under the transKeepSign argument is cut off:

Can you please provide more information about what this argument is doing? The comment thread in the issue that gave rise to the inclusion of this argument implies that the purpose of the argument is to specify the range in which a color gradient will be applied. However, the description in the reference manual states that this argument dictates whether matrix values' signs are kept when non-correlation matrices are transformed for plotting. I am having difficulty understanding the proper use case of this argument and further clarification would be helpful.

Thank you for your time!
