Given a YAML field name, find the (R) Markdown files that contain this field
and its value contains any of the specified values. Functions
find_tags() and find_categories() are wrappers of
find_yaml() with field = 'tags' and field =
'categories', respectively; count_fields() returns the frequency
tables of the specified YAML fields, such as the counts of tags and
categories.
Usage
find_yaml(field = character(), value = character(), open = FALSE)
find_tags(value = character(), open = FALSE)
find_categories(value = character(), open = FALSE)
count_yaml(fields = c("categories", "tags"), sort_by_count = TRUE)
Arguments
- field, fields
A character vector of YAML field names.
- value
A vector of the field values to be matched.
- open
Whether to open the matched files automatically.
- sort_by_count
Whether to sort the frequency tables by counts.
Value
find_yaml() returns a character vector of filenames;
count_yaml() returns a list of frequency tables.
