## load the package
library(foghorn)

foghorn provides the results of the package CRAN checks. As a maintainer, you can easily get the results of the checks for your packages by using the email address included in the DESCRIPTION file of your packages.

summary_cran_results() provides you with a graphical summary of the results of the CRAN checks. The number in parenthesis after the name of the package indicates the number of platforms used by CRAN that produced this result.

## Graphical interface
summary_cran_results(email = "francois.michonneau@gmail.com")
## ✔ All clear for foghorn, riceware!
## ★  Packages with notes on CRAN: 
##   - phylobase (1)
##   - rncl (13)
##   - rotl (12)

summary_cran_results() is actually an alias of summary(cran_results()), meaning that you can call cran_results() directly if you want to easily access the underlying data for the results of the CRAN checks. These results are stored in a tibble.

## Results as a tibble
cran_results(email = "francois.michonneau@gmail.com")
## # A tibble: 5 x 7
##   package   error  fail  warn  note    ok has_other_issues
##   <chr>     <int> <int> <int> <int> <int> <lgl>           
## 1 foghorn       0     0     0     0    14 FALSE           
## 2 phylobase     0     0     0     1    13 FALSE           
## 3 riceware      0     0     0     0    14 FALSE           
## 4 rncl          0     0     0    13     1 FALSE           
## 5 rotl          0     0     0    12     2 FALSE

In addition of your own packages, you can also check the results for any other packages that might be of interest to you:

## either by themselves
summary_cran_results(pkg = c("ggplot2", "dplyr"))
## ✖  Package with errors on CRAN: 
##   - dplyr (1)
## ★  Packages with notes on CRAN: 
##   - dplyr (7)
##   - ggplot2 (7)
cran_results(pkg = c("ggplot2", "dplyr"))
## # A tibble: 2 x 7
##   package error  fail  warn  note    ok has_other_issues
##   <chr>   <int> <int> <int> <int> <int> <lgl>

## 2 ggplot2     0     0     0     7     7 FALSE
## or by combining them with email addresses

You can inspect the logs for the check results using summary_cran_details(pkg) (or summary(cran_details(pkg))), while visit_cran_check(pkg) takes you directly to the CRAN webpage.

tidyr_details <- cran_details(pkg = "tidyr")

Where does it get the data?

The data from the check results used by this package are either scrapped from the CRAN web pages (default), or are from the CRAN database (that CRAN uses to build the webpages). The first option is faster if you want to regularly check a few packages. However, if you are doing statistics on a large number of packages, using the CRAN database is recommended (it’s about 20Mb of data). To use the CRAN database, add src = "crandb" in your function calls:

cran_results(pkg = "nlme", src = "crandb")

Check out the “Details” section in the help files for more information.
