I've run the following code according to the tutorial: http://kasperdanielhansen.github.io/genbioconductor/html/SummarizedExperiment.html
library(GenomicRanges) library(airway) library(SummarizedExperiment) data(airway) # loads data into R airway colData(airway) airway$cell # to know how the experiment was made: exptData(airway)
however when runs exptData(airway) it throws the
Error: could not find function "exptData"
Could someone please tell what am I missing?
