Run 'R CMD check' from 'R' and Capture Results

Run 'R CMD check' from 'R' and capture the results of the individual checks. Supports running checks in the background, timeouts, pretty printing and comparing check results.

Results

Run R CMD check form R programatically, and capture the results of the individual checks.

Installation

source("https://install-github.me/r-lib/rcmdcheck")

Usage

library(rcmdcheck)
rcmdcheck("path/to/R/package")

Call rcmdcheck() on a source R package .tar.gz file, or on a folder containing your R package. Supply quiet = FALSE if you want to omit the output. The result of the check is returned, in a list with elements errors, warnings, and notes. Each element is a character vector, and one element of the character vectors is a single failure.

Programmatic usage

rcmdcheck() returns an rcmdcheck object, which you can query and manipulate.

library(rcmdcheck)
chk <- rcmdcheck("tests/testthat/bad1", quiet = TRUE)
chk
#> ── R CMD check results ────────────────────────────── badpackage 1.0.0 ────

#>   Standardizable: FALSE
#> 
#> 0 errors ✔ | 1 warning ✖ | 0 notes ✔

check_details() turns the check results into a simple lists with the following information currently:

names(check_details(chk))
#>  [1] "package"      "version"      "notes"        "warnings"    
#>  [5] "errors"       "platform"     "checkdir"     "install_out" 
#>  [9] "description"  "session_info" "cran"         "bioc"

• package: Package name.
• version: Package version number.
• notes: Character vector of check NOTEs.
• warnings: Character vector of check WARNINGs.
• errors: Character vector of check ERRORs.
• platform: Platform, e.g. x86_64-apple-darwin15.6.0.
• checkdir: Check directory.
• install_out: Output of the package installation.
• description: The text of the DESCRIPTION file.
• session_info: A sessioninfo::session_info object, session information from within the check process.
• cran: Flag, whether this is a CRAN package. (Based on the Repository field in DESCRIPTION, which is typically only set for published CRAN packages.)
• bioc: Flag, whether this is a Bioconductor package, based on the presence of the biocViews field in DESCRIPTION.

Note that if the check results were parsed from a file, some of these fields might be missing (NULL), as we don’t have access to the original DESCRIPTION, the installation output, etc.

Parsing check output

parse_check() parses check output from a file, parse_check_url() parses check output from a URL.

CRAN checks

rcmdcheck has a functions to access CRAN’s package check results.

cran_check_flavours() downloads the names of the CRAN platforms:

cran_check_flavours()

#>  [2] "r-devel-linux-x86_64-debian-gcc"

cran_check_results() loads and parses all check results for a package.

Comparing checks

compare_checks() can compare two or more rcmdcheck objects. compare_to_cran() compares an rcmdcheck object to the CRAN checks of the same package:

chk <- rcmdcheck(quiet = TRUE)
compare_to_cran(chk)
#> ─ R CMD check comparison  rcmdcheck 1.3.3 / 1.3.2 / 1.3.2 / 1.3.2 / 1.
#> Status: OK
#> 
#> ── Fixed
#> 
#> ✔ checking tests ... [41s] ERROR
#> ✔ checking tests ... [38s] ERROR

Background processes

rcmdcheck_process is a processx::process class, that can run R CMD check in the background. You can also use this to run multiple checks concurrently. processx::process methods can be used to poll or manipulate the check processes.

chkpx <- rcmdcheck_process$new()
chkpx
#> PROCESS 'R', running, pid 90876.

chkpx$wait()
chkpx$parse_results()
#> ── R CMD check results ─────────────────────────────── rcmdcheck 1.3.3 ────
#> Duration: 14.8s
#> 
#> 0 errors ✔ | 0 warnings ✔ | 0 notes ✔
