Parse a highlight string into the values it names

Source: R/parse_utils.R
parse_highlight_values.Rd

Highlight values are typed as a comma- or newline-separated list, and may also be separated by spaces. A value containing a space ("CD4 T", "Player A") would be impossible to name that way, so each comma- or newline-delimited entry is kept whole when it is one of available, and split on whitespace otherwise.

Usage

parse_highlight_values(x, available = NULL)

Arguments

x

A single string, e.g. "CD4 T, B" or "P01 P07", or NULL.

available

Character vector of the values the entries name (the annotate.by column), or NULL to split every entry on whitespace.

Value

A character vector of unique, non-blank values, possibly empty.
