roperators 1.4.0 (2026-06-03)

New features

• f() — string interpolation ("f-strings"): f("Hi {name}, you have {n} messages").
• %else% — inline fallback for an expression that might error: read.csv(path) %else% data.frame().
• %+-% — tolerance-interval constructor that composes with the between operators: x %><% (5 %+-% 0.5).
• %/0% — safe division that returns NA instead of Inf/NaN on divide-by-zero.
• %~% — case- and whitespace-insensitive string equality (the string counterpart to %~=%).
• as.percent() — format a proportion as a percentage string.

Bug fixes

• is.bad_for_calcs() now correctly flags Inf/-Inf as bad for calculations. Previously infinities slipped through, which also affected the comparison operators (%==%, %>=%, ...) that rely on it.
• is.R_x64() now calls is.os_unx() correctly (it previously referenced the function without calling it).
• seq_around() now accepts ordinary numeric values for n; it previously errored unless n was given as an explicit integer (e.g. 5L).
• The between operators (%><%, %>=<%) now handle reversed bounds, so 5 %><% c(10, 1) behaves the same as 5 %><% c(1, 10).
• %na<-% now also accepts a replacement vector with one entry per missing value (filled in order), in addition to a scalar or a full-length vector.
• Removed a stray duplicate (and subtly broken) internal definition of is.bad_for_calcs().

Improvements

• as.class() is now vector-safe and no longer builds and parses code from a string internally.
• is.http_available() uses requireNamespace() instead of the much slower installed.packages().
• get_system_python(), is_rda_file(), and is_rds_file() are now exported (they were documented in earlier versions but never actually exported).

Documentation, tests & infrastructure

• Documentation overhaul for clarity and consistency: tightened every help page, fixed typos throughout, and added missing \value documentation and runnable examples.
• %rlike% and %perl% now have their own help page ("SQL-style pattern matching") instead of being grouped under the logical operators.
• Rewritten, comprehensive vignette and a README.Rmd so the README's output is always real.
• Added a full testthat test suite covering the operators and helpers, a BugReports URL, a pkgdown site configuration, and GitHub Actions for R-CMD-check and pkgdown deployment.

roperators 1.3.14 (2023-07-20)

• added is.os_arm() to check if running ARM cpu
• added get_R_version() to pull current R version
• added get_R_version_age() to find how old the installed R version is
• added get_latest_CRAN_version() to find the latest version on CRAN (rvest required)
• added get_system_python() to return default python called in system calls to "python"
• added %C% for choose operator and %P% for permute
• added %integrate% for inline integrations
• added is.http_available() to check whether you can send an HTTP request (via httr, RCurl, or a system call to curl).

roperators 1.3.0

• added seq_around() for evenly spaced sequences around an origin point
• Cleaned up roxygen comments, DESCRIPTION, and NAMESPACE files.
• Added a NEWS.md file to track changes to the package.
• New complete cases functions (length_cc(), min_cc(), max_cc(), range_cc(), all_cc(), any_cc(), sum_cc(), prod_cc(), mean_cc(), median_cc(), var_cc(), cov_cc(), cor_cc(), sd_cc(), weighted.mean_cc(), quantile_cc(), IQR_cc(), mad_cc(), rowSums_cc(), colSums_cc(), rowMeans_cc(), colMeans_cc()) that set default argument to standard base/stats functions for only calculating on complete cases.
• New get_os(), is.os_mac, is.os_win, is.os_lnx, and is.os_unx helper functions to quickly determine operating system.
• New is_txt_file(), is_csv_file(), is_excel_file(), is_r_file(), is_rdata_file(), is_rda_file(), is_spss_file(), and check_ext_against() functions to quickly determine if file has specific file extensions.
• New is.R_Revo() and is.RStudio() functions to determine whether Revolution R and RStudio are installed.
• New n_unique() function to count unique items and n_unique_cc() version for complete cases.
• New is.constant() and is.binary() functions to indicate whether a vector is constant (contains only ONE value type, ignoring NA) or binary (contains at most TWO value types, ignoring NA).
• New get_most_frequent() function to get most frequent thing(s) in x.
• New get_most_frequent_word() function to get most frequent word from string.
• New get_nth_word() function to get nth word from string
• New as.class() pipe-able function for arbitrary class conversions
• New paste_()is the same as paste0 but uses an underscore to separate
• New cat0() is analogous to paste0 but for cat
• New catN() is the same as cat0 but automatically inserts a new line after the cat
• New paste_series() paste a series of things with a conjunction
• New paste_oxford() shortcut for paste_series as oxford comma
