Say you have a number of files with "5min" in their names, number with "10min" in the names, a number with "15min" in their names and so on, and you'd like to put them into directories named "5min", "10min", "15min" and so on. This function does this, but not just for the unit "min", for any unit.
unitize_dirs(unit, pattern = NULL, dir = ".")The unit upon which to base the categorizing.
If set, only files with names matching this pattern will be treated.
In which directory do you want to perform this action (defaults to current)?
Invisibly TRUE if the operation is successful, if not there will be
an error.
This function takes the number to be the last number (as defined in
nth_number()) before the first occurrence of the unit name. There is the
option to only treat files matching a certain pattern.
if (FALSE) {
dir.create("UnitDirs_test")
setwd("UnitDirs_test")
files <- c("1litres_1.txt", "1litres_3.txt", "3litres.txt", "5litres_1.txt")
file.create(files)
unitize_dirs("litres", "\\.txt")
setwd("..")
dir.remove("UnitDirs_test")
