In hutils: Miscellaneous R Functions and Aliases

hutils 1.8.1

• Internal:

• Fix class() == "character" infelicity

• Enhancements

• select_which gains argument .and.grep

hutils 1.8.0

• Bug fixes:

• longest_affix now correctly returns single character prefixes. (#40) Thanks to @piosierra for reporting.

• New functions

• seq_nrow(x) = seq_len(nrow(x)) for abbreviation

• fst_columns, fst_nrow the names nrow of an fst file

• Enhancements:

• if_else now supports raw output

• Performance:

• drop_empty_cols uses is.na(x[1]) rather than anyNA(x) for higher performance on non-empty columns and hutilscpp if available

hutils 1.7.1

• Technically breaking change:
• test_1-3-0_weighted_ntile.R has been modified to skip a test which relied on old behaviour of package survey. I have not accompanied this with a major version change.

hutils 1.7.0

• Mode is now less clever and more speedy for sparse integer inputs

hutils 1.6.0

• New functions
• goto_pattern_in an enhancement of find_pattern_in to jump to a line in RStudio.
• prohibit_ functions for argument checking

hutils 1.5.1

• Bug fixes:

• weighted_ntile is less susceptible to integer overflow (#36)

• Internal

• Version dependencies now have no upper bound for recommended packages, to avoid issues with CRAN.

hutils 1.5.0

• Bug fixes:

• samp works with size > length.

• New functions

• provide.file To ensure a file (including its directory) exists.

• Enhancements:

• provide.dir returns the directory requested on success.

hutils 1.4.0

• New functions:
• %<->% 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.

• Enhancements

• 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.

hutils 1.3.0

• Bug fixes:

• weight2rows:

  • no longer reorders the columns in the result
  • no longer updates by reference the data frame to be a data.table, instead a copy is made

• New functions:

• weighted_quantile, like quantile but for weighted data
• weighted_ntile, like dplyr::ntile but for weighted data
• mutate_ntile convenience function for adding new column with ntiles

• trim_common_affixes, and associated helpers longest_prefix and longest_suffix.

• Enhancements:

• weight2rows gains a rows.out argument to specify the number of rows in the result.

hutils 1.2.0

• New functions:
• RQ(p, yes, no) short for if (!requireNamespace("p", quietly = TRUE)) yes else no.
• isAttached for conveniently determining whether a namespace is attached
• ahull for locating rectangles in a plot, as for automatically locating a text box.
• Switch vectorized version of switch to avoid nested if_else's.

• drop_grep is an alias for drop_colr.

• Minor changes:

• if_else reports a clearer error message when length(condition) == 1.

hutils 1.1.1

• Change of stable test:

  • The only changes were so that the test proceeds when a required package is present. The tests would never have succeeded in cases where they now skip. Consequently the major version number has not been incremented.

• Bug fix:

  • find_pattern_in respects include.comments
• Enhancement:
  • find_pattern_in accepts argument which_lines to allow multiple lines per file, not just the first (the default).

hutils 1.1.0

• New functions:

  • auc: area under the curve given predicted and actual values.
  • select_grep: select columns matching a pattern.
  • dev_copy2a4: convenience function for copying to an A4 PDF.

• Other minor changes:

• if_else should be slightly faster when the condition contains NAs. before: 3.6 ms now 1.5 ms (for 100,000 entries -- see vignette)
• drop_constant_cols first checks whether the first and second entries are identical before working out the number of unique values.

hutils 1.0.0

• Stable release:
• All tests are now marked as major release.
• New function %notchin% for a 'safer' alternative to %notin%.

hutils 0.10.0

• New function implies, logical implies.
• New function drop_constant_cols
• New function print_transpose_data_table for glimpsing data tables by rows
• New alias pow for exponentiation.
• Bug fixes:
  • Ensure drop_empty_cols retains non-empty columns when duplicate names are used.
  • coalesce errors if there is ... wrongly contains factors.

hutils 0.9.0

• Changed if_else to reflect dplyr's formals so it can be a drop-in replacement.
• Fix error for multi-length missing value in if_else when length-one condition.
• Add vignette
• Minor performance improvements

hutils 0.8.0

• Added a NEWS.md file to track changes to the package.
• New functions
  • %ein% %enotin% avoid misspellings in filters
  • AND, NEITHER, NOR, OR, nor, neither logical aliases
  • drop_colr drop columns matching pattern
  • ngrep negate regular expression
  • select_which similar to dplyr::select_if
  • set_colsuborder change the order of some columns without affecting the order of others
  • weight2rows convert a weighted data.table to an unweighted one by repeating rows by the weight
  • coalesce and if_else: lightweight versions of dplyr:: equivalents
• Bug fixes:
  • set_cols_first|last now respects the order of the supplied columns
• Enhancements:
  • mutate_other now accepts a mass argument as another way to generate an 'Other' column.
