WebDownsampling is done without replacement, meaning that rows are not duplicated but only removed. With `id_col` See `id_method` description. Value data.frame with some rows removed. Ordered by potential grouping variables, `cat_col` and (potentially) `id_col` . Author (s) Ludvig Renbo Olsen, [email protected] See Also WebThe whole reason for "downsampling" is to create an "access" image that is a miniaturized duplicate of your optical resolution "master" scan. The advantage of having both the master and the "access" files differ only in resolution, but at the same height and width is they can be used as a true "proxy."
