Checks if all values match regular expression using
all(grepl(regexp, x[!is.na(x)]))
chk_match(x, regexp = ".+", x_name = NULL)vld_match(x, regexp = ".+")
vld_match(x, regexp = ".+")
The chk_ function throws an informative error if the test fails or returns the original object if successful so it can used in pipes.

The vld_ function returns a flag indicating whether the test was met.
vld_
The object to check.
A string of a regular expression.
A string of the name of object x or NULL.
