R Documentation

Gets the tags

Description

Gets the tags.

Usage

## S3 method for class 'FullNameInterface'
getTags(this, pattern=NULL, collapse=NULL, ..., named=FALSE, na.rm=TRUE,
  useCustomTags=TRUE)

Arguments

`pattern`	An optional regular expression used to filter out tags. If `NULL`, all tags are returned.
`collapse`	A `character` string used to concatenate the tags. If `NULL`, the tags are not concatenated.
`...`	Additional arguments passed to `*getFullName()`.
`named`	If `TRUE`, tags of format "<name>=<value>" will be parsed as named "<value>" tags, e.g. `"foo,n=23,bar,n=42"` is parsed to `c("foo", "n"="23", "bar", "n"="42")`. Note that if `collapse` is `FALSE`, the names will be dropped.
`na.rm`	If `TRUE` and the fullname is `NA`, then `NULL` is returned, otherwise (character) `NA` is returned.
`useCustomTags`	If `TRUE`, custom tags are used, otherwise not.

Details

The tags of a fullname are the comma separated parts of the fullname that follows the the first comma, if any. For instance, the tags of foo,a.2,b are a.2 and b.

Any custom tag that equals "*" is replaced by the comma separated tags from the fullname.

Value

Returns a character vector (possibly NA) or NULL.
