In tidytuesdayR there are nice print methods for the objects that were used to download and store the data from the TidyTuesday repo. They will always print the available datasets/files. If there is a readme available, it will try to display the TidyTuesday readme.
Examples
if (FALSE) { # interactive()
tt <- tt_load_gh("2019-01-15")
print(tt)
tt_data <- tt_download(tt, files = "All")
print(tt_data)
}
