问题
In corrplot in R, we can highlight insignificant correlation (<0.05) by supplying p-value matrix and using function "insig" and "pch".
But I want highlight only Significant correlation having p-value less than 0.05.
Is there any way to do the opposite?
Best regards

I looked into the source code of corrplot. As far as I understand the code, it is not possible to do the exact opposite to the significant values. The only option that comes really close to what you want is defining insig = "blank". This will cause the non-significant correlations to simply disappear.
The best solution I can think of is to contact the author of the package and ask if this can be implemented: https://cran.r-project.org/web/packages/corrplot/index.html
An other option is to tweak the source code of corrplot yourself, to adjust it to your needs.
Also, if you haven't yet, check out the vignettes for corrplot: https://cran.r-project.org/web/packages/corrplot/vignettes/corrplot-intro.html
Edit: Or, specify insig = blank, which I think comes pretty close to what you want.. not sure.
