# to read "data.fam", run like this: # fam <- read_fam("data") # this also works # fam <- read_fam("data.fam") # The following example is more awkward # because package sample data has to be specified in this weird way: # read an existing Plink *.fam file file <- system.file("extdata", 'sample.fam', package = "genio", mustWork = TRUE) fam <- read_fam(file) fam # can specify without extension file <- sub('\\.fam$', '', file) # remove extension from this path on purpose file # verify .fam is missing fam <- read_fam(file) # load it anyway! fam
