Returns interval set attributes values

Returns interval set attributes values.

gintervals.attr.export(intervals.set = NULL, attrs = NULL)

Arguments

intervals.set

a vector of interval set names or 'NULL'

attrs

a vector of attribute names or 'NULL'

Value

A data frame containing interval set attribute values.

Details

This function returns a data frame that contains interval set attribute values. Column names of the data frame consist of the attribute names, row names contain the interval set names.

The list of required interval sets is specified by 'intervals.set' argument. If 'intervals.set' is 'NULL' the attribute values of all existing interval sets are returned.

Likewise the list of required attributes is controlled by 'attrs' argument. If 'attrs' is 'NULL' all attribute values of the specified interval sets are returned. The columns are sorted then by "popularity" of an attribute, i.e. the number of interval sets containing this attribute. This sorting is not applied if 'attrs' is not 'NULL'.

Empty character string in a table cell marks a non-existing attribute.
