How to cite

The R core development team and the very active community of package authors have invested a lot of time and effort in creating R as it is today. Please give credit where credit is due and cite R and R packages when you use them for data analysis. To cite corrplot properly, call the R built-in command citation("corrplot") as follows:


Basic example

M <- cor(mtcars)
corrplot(M, order = "hclust", addrect = 2)

Reporting bugs and other issues

If you encounter a clear bug, please file a minimal reproducible example on github.

How to perform static code analysis and style checks

We use lintr which also performs the analysis on Travis-CI. Configuration for lintr is in .lintr file. Lints are treated as warnings, but we strive to be lint-free.

In RStudio, you can run lintr from the console as follows:

> lintr::lint_package()
