There should be at least two columns - one called basename (containing the basename of the samples) and another containing the contrasts of interest. Another column containing an additional factor of interest which should be taken into account may also be included.

Usage

load_samples(sample.path = NULL, contrast.column = NULL,
  block.column = NULL, contrast.levels)

Arguments

sample.path	Character string. Full path to sample metadata file.
contrast.column	Chacter string. Column in sample metadata file that contains the contrasts of interest.
block.column	Character string. Column in sample metadata file that contains blocking factors.
contrast.levels	Character vector. The contrast levels listed in the order they should be compared as present in the contrast column of the metadata file (e.g. c("WT", "KO")).

Value

A dataframe of the sample metadata.
