## Convert WIG to BigWig

### Description

This function calls the Kent C library to efficiently convert a WIG file to a BigWig file, without loading the entire file into memory. This solves the problem where simple tools write out text WIG files, instead of more efficiently accessed binary BigWig files.

### Usage

    wigToBigWig(x, seqinfo,
                dest = paste(file_path_sans_ext(x, TRUE), "bw", sep = "."),
                clip = FALSE)

### Arguments

`x` | Path or URL to the WIG file. Connections are not supported.
`seqinfo` | `Seqinfo` object, describing the genome of the data. All BigWig files must have this defined.
`dest` | The path to which to write the BigWig file. Defaults to `x` with the extension changed to “bw”.
`clip` | If `TRUE`, regions outside of `seqinfo` will be clipped, so that no error is thrown.
