Title

Trait names are distinct within a dataset, but may be duplicated in different datasets (for instance same type of trait in two tissues). The `object` will have a column `dataset` if it comprises multiple datasets, but it is also possible that the `dataset` column is absent (in case there is only one dataset).

Usage

trait_names(object, traitnames = NULL, sep = ": ")

Arguments

object

data frame or object containing dataset and trait columns

traitnames

names of traits, possibly including dataset name with separator

sep

separator character(s) between dataset and trait name

Value

vector of trait names prepended by dataset if appropriate

Details

The argument `traitnames` can be one of the following: 1. names found in `trait` column that are distinct across any possible datasets. 2. name of the form `dataset: trait`, that is, separated by the `sep` string. 3. data frame with columns for `dataset` and `trait`, with one row entry per traitname. 4. NULL, in which case all `datatraits` in `object` are returned

Examples

trait_names(sampleData, c("A","C"))
#> [1] "sample: C" "sample: A"
