Solution

  • .Callis used to call compiled code (dll or equivalent). The only way is to retrieve the source package (the .tar.gz), uncompress and have a look at the source code -- Cf https://cran.r-project.org/web/packages/mcga/index.html; uncompress and have a look at "src" folder (seems to be C code in that case)
