var_names R Documentation
Extract variable names from predicates
Description
The function assumes that x is a vector of predicate names, i.e., a character
vector with elements compatible with pattern <varname>=<value>. The function
returns the <varname> part of these elements. If the string does not
correspond to the pattern <varname>=<value>, i.e., if the equal sign (=)
is missing in the string, the whole string is returned.
Usage
var_names(x)
Arguments
x
A character vector of predicate names.
Value
A <varname> part of predicate names in x.
Author(s)
Michal Burda
Examples
var_names(c("a=1", "a=2", "b=x", "b=y")) # returns c("a", "a", "b", "b")
