as.qtag: Convert an object to a qualifier/tag structure

In mudata: Interchange Tools for Multi-Parameter Spatiotemporal Data

Description

A qualifer/tag structure is an experimental version of a data frame that stores id.vars and measure.vars with the data structure, so it can be handled in a more automatic way. This functionality is experimental.

Usage

as.qtag(df, id.vars = NA, measure.vars = NA, tag.vars = NA,
  quiet = FALSE)

qtag(df, ...)

Arguments

df	A data.frame or similar object
id.vars	Column names of qualifying measure.vars (NA to guess)
measure.vars	Column names containing the values of interest (NA to guess)
tag.vars	Column names of tag values
quiet	Use quiet=TRUE to suppress error messages
...	Passed to/from methods

Value

An object of type qtag, which is essentially the unchanged input with id.vars, measure.vars, and tag.vars information attached.

Examples

data("pocmaj")
pocmaj <- as.qtag(pocmaj, id.vars = c("core", "depth"))
long(pocmaj)
aggregate(pocmaj)
aggregate(long(pocmaj))
