Overview

About

Maintained by Joe ThorleyCRAN page ↗GitHub ↗Website ↗Issues ↗Declared funder: Poisson Consulting

For developers to check user-supplied function arguments. It is designed to be simple, fast and customizable. Error messages follow the tidyverse style guide.

Changes in 0.11.0

Breaking changes

chk now requires R >= 4.1.
check_data() and check_values() now require the levels of a factor column to be identical (including order) to the levels of values whenever values has two or more levels; previously two levels only required an ordered superset (#297).
check_data() and check_values() now require all values of a column to be missing when the corresponding values are all missing.

New features

New chk_all_na() and vld_all_na() check that all values are missing (#299).
New chk_class() and vld_class() check that an object inherits from a class using inherits() regardless of the object system.
New chk_s3_class_strict() and vld_s3_class_strict() check that an object is an S3 object of the given class (excluding S4, R5, R6 and S7 objects).
New chk_r6_class() and vld_r6_class() check that an object is an R6 object of the given class (#306).
New generate_check_data() generates the code for a check_data() call from an example data frame (#124).
chk_s3_class() and chk_s4_class() errors now state the class(es) of the object to help diagnose issues.
chkor_vld() gains an x_name argument that is passed to each of the underlying chk_ calls, so the error message refers to x_name rather than the deparsed vld_ arguments (#100).

Show all changes in 0.11.0Hide the rest of the changes in 0.11.0

vld_s4_class() is now vectorized over class like vld_s3_class(), so chk_s4_class() accepts multiple classes.
message_chk() gains a %es sprintf-like type (for pluralizing words such as class/classes) and treats %% as an escape for a literal '%' (#310).
p() and p0() gain a recycle0 argument that is passed to paste() and paste0() (#307).

Bug fixes

check_data() now names the offending argument when passed a non-data frame, instead of reporting "data.frame".
chk_lte() now sets the x and value fields on its condition for scalar input, consistent with chk_gte(), chk_lt() and chk_gt().
chk_null_or() now resolves the matching chk_ function by direct lookup (including chk_/vld_ pairs defined in other packages) rather than by parse()/eval(), and falls back to an informative message when no partner can be found (#97).
deparse_backtick_chk() now uses deparse1() so that x_name is a string for arguments whose expressions deparse over multiple lines; previously such calls failed with ` x_name must be a string ` (#300).

Documentation

check_data() now documents that it does not check for duplicate rows and that unique() should be used to detect them (#309).

From NEWS.md in the release

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("chk", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("poissonconsulting/chk")

Development version from poissonconsulting/chk. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-chk

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-chk

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-chk

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
