dupree_package

R Documentation

Run duplicate-code detection over all files in the 'R' directory of a package

The function fails if the path does not look like a typical R package (it should have both an R/ subdirectory and a DESCRIPTION file present).

dupree_package(package = ".", min_block_size = 40)

`package`	The name or path to the package that is to be checked (By default the current working directory).
`min_block_size`	`dupree` uses a notion of non-trivial symbols. These are the symbols / code-words that remain after filtering out really common symbols like `<-`, `,`, etc. After filtering out these symbols from each code-block, only those blocks containing at least `min_block_size` symbols are used in the inter-block code-duplication measurement.
