Imported selection helpers from package 'tidyselect'

These selection helpers match variables according to a given pattern.

• starts_with(): Starts with a prefix.

• ends_with(): Ends with a suffix.

• contains(): Contains a literal string.

• matches(): Matches a regular expression.

• num_range(): Matches a numerical range like x01, x02, x03.

starts_with(match, ignore.case = TRUE, vars = NULL)

ends_with(match, ignore.case = TRUE, vars = NULL)

contains(match, ignore.case = TRUE, vars = NULL)

matches(match, ignore.case = TRUE, perl = FALSE, vars = NULL)

all_of(x)

any_of(x, ..., vars = NULL)

Arguments

match	A character vector. If length > 1, the union of the matches is taken.
ignore.case	If TRUE, the default, ignores case when matching names.
vars	A character vector of variable names. If not supplied, the variables are taken from the current selection context (as established by functions like select() or pivot_longer()).
perl	Should Perl-compatible regexps be used?
