gff_get_attribute: Parse gff field
In luisvalesilva/hwglabr: Collection of R functions used in the Hochwagen Lab

Description Usage Arguments Value Details Examples

This function allows you to parse the complex 'attributes' column of a gff file and get only feature names or IDs, for example. Adapted from function in the davidTiling experimental package. Also posted on the Bioconductor support system here.

1	gff_get_attribute(gffColumn, field, attrSep = ";")

`gffColumn`	The column of the Gff file to parse, typically 'attributes'. No default.
`field`	A string representing the field with the value you want (formatted as `field = value;`). No default.
`attrSep`	A string representing the field separator (`;` in the standard gff format). Defaults to `;`.

A vector containing the specified field values of the same size as the number of features in the gff file.

Typical use of this function will include first using gff_read, also in this package, to load gff file and then parsing the attributes field. See examples below.

## Not run:
