checkMD5sums {tools} | R Documentation

## Check and Create MD5 Checksum Files

### Description

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

### Usage

    checkMD5sums(pkg, dir)

### Arguments

`pkg` | 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. (One is supplied in the bundle at http://www.murdoch-sutherland.com/Rtools/tools.zip.)

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