Convert a linked data frame to labels — as_dataframe_of

This takes a data frame containing ldf_resource or ldf_interval vectors and converts those vectors into labels.

as_dataframe_of_labels(d, ...)

Arguments

d	A linked data frame
...	Additional arguments passed to `data.frame`

Value

A data frame with labels in place of any ldf vectors

Details

The labels will either be character vectors or factors depending on the value of default.stringsAsFactors(). This can be ridden by passing the argument stringsAsFactors=F.

Examples

uris <- c("http://example.net/id/apple",
          "http://example.net/id/banana",
          "http://example.net/id/carrot")
labels <- c("Apple","Banana","Carrot")
description <- data.frame(uri=uris, label=labels)

linked_data_frame <- data.frame(fruit=resource(uris, description))
labelled_data_frame <- as_dataframe_of_labels(linked_data_frame, stringsAsFactors=FALSE)
