Run R CMD check from R and Capture Results

rcmdcheck

Run R CMD check from R and Capture Results

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

Installation

install.packages("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 ────
#> Duration: 11s
#> 
#> ❯ checking DESCRIPTION meta-information ... WARNING
#>   Non-standard license specification:
#>     Public domain
#>   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()
#>  [1] "r-devel-linux-x86_64-debian-clang"
#>  [2] "r-devel-linux-x86_64-debian-gcc"

#>  [4] "r-devel-linux-x86_64-fedora-gcc"

#> [11] "r-oldrel-osx-x86_64"

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 1.3.2.9002 / 1.3.2 / 1.3.2 / 1.3.2
#> 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 61974.

chkpx$wait()
chkpx$parse_results()
#> ── R CMD check results ────────────────────────── rcmdcheck 1.3.2.9002 ────
#> Duration: 15.2s
#> 
#> 0 errors ✔ | 0 warnings ✔ | 0 notes ✔
