weighted_ntile is less susceptible to integer overflow (#36)samp works with size > length.provide.file To ensure a file (including its directory) exists.provide.dir returns the directory requested on success.%<->% To swap values between objects
average_bearing, the bearing bisecting two vectors
dir2, (Windows only) a much faster version of dir()
Mode, statistical mode
replace_pattern_in to find-and-replace on a pattern in all files in a directory
samp, a ‘safe’ version of sample.
drop_empty_cols should now be faster, especially when there are few empty columns.weight2rows supports rows.out < 1 to produce a sample.weight2rows is now faster for default arguments, by using the rep(x, w) trick used in tidyr::uncount.mutate_ntile now works for a variable with DT
find_pattern_in now accepts file_contents_ignore_case.find_pattern_in no longer complains about perl, fixed conflicts.weight2rows:
weighted_quantile, like quantile but for weighted dataweighted_ntile, like dplyr::ntile but for weighted datamutate_ntile convenience function for adding new column with ntilestrim_common_affixes, and associated helpers longest_prefix and longest_suffix.weight2rows gains a rows.out argument to specify the number of rows in the result.New functions:

Minor changes:
if_else reports a clearer error message when length(condition) == 1.find_pattern_in respects include.comments
