glob: Select helper to select variables based on name glob pattern.
In jrnold/rubbish: Miscellaneous functions

Description Usage Arguments Details Value

Like matches, this function selects variables by by name. However, it uses wildcard, aka globbing patterns instead of regular expressions.

1	glob(pattern, ignore.case = TRUE, vars = current_vars())

`pattern`	Globbing pattern
`ignore.case`	If `TRUE`, the default, ignores case when matching names.
`vars`	A character vector of variable names. When called from inside `select()` these are automatically set to the names of the table.

Use ? to match a single character, and * to match any number of characters, including none. The pattern is anchored at the start and end of the string, meaning it must start at the start, and end at the the end.

This function uses glob2rx to convert the globbing pattern to a regex,

An integer vector given the position of the matched variables.
