R: Check and Create MD5 Checksum Files

checkMD5sums {tools} | R Documentation

## Check and Create MD5 Checksum Files

### Description

`checkMD5sums` checks the files against a file ‘MD5’.

### Usage

    checkMD5sums(package, dir)

### Arguments

`package` | the name of an installed package
`dir` | the path to the top-level directory of an installed package.

### Details

The file ‘MD5’ which is created is in a format which can be checked by `md5sum -c MD5` if a suitable command-line version of `md5sum` is available. (For Windows, one is supplied in the bundle at https://cran.r-project.org/bin/windows/Rtools.)

If `dir` is missing, an installed package of name `package` is searched for.

The private function `tools:::.installMD5sums` is used to create `MD5` files in the Windows build.

### Value

`checkMD5sums` returns a logical, `NA` if there is no ‘MD5’ file to be checked.
