In tidymodels/recipes: Preprocessing and Feature Engineering Steps for Modeling

low_range <- paste0("\`", prefix, 1, "\` - \`", prefix, 9, "\`")
high_range <- paste0("\`", prefix, 001, "\` - \`", prefix, 101, "\`")

The argument num_comp controls the number of components that will be retained (the original variables that are used to derive the components are removed from the data). The new components will have names that begin with prefix and a sequence of numbers. The variable names are padded with zeros. For example, if num_comp < 10, their names will be r low_range. If num_comp = 101, the names would be r high_range.
