We maintain an API (https://cranchecks.info/) that gives you access to CRAN checks data. The code for the API lives at GitHub - sckott/cchecksapi: CRAN checks API (DEFUNCT)
We have an accompanying R package cchecks that works with the API.
The API also has badges - see e.g., on the data.table site Home · Rdatatable/data.table Wiki · GitHub - it’s the one that looks something like (exact look depends on what the checks say)
Here’s an example of using the R package
setup
remotes::install_github("ropenscilabs/cchecks")
library(cchecks)
library(dplyr)
get data
x <- lapply(seq(0, 13000, by = 1000), function(off) {
cch_pkgs(limit = 1000, offset = off)
})
## prepare data for below
df <- tbl_df(bind_rows(lapply(x, function(z) {
cbind(
select(z$data, package),
select(z$data$check_details, output, check)
)
})))
quick overview of check results
The summary data slot tallies the number of checks across R version and
operating system that have different outcomes. We can summarize those
across packages:
stats <- tbl_df(bind_rows(lapply(x, function(w) w$data$summary)))
stats
#> # A tibble: 13,527 x 6
#> any ok note warn error fail
#> <lgl> <int> <int> <int> <int> <int>
#> 1 FALSE 12 0 0 0 0
#> 2 FALSE 12 0 0 0 0
#> 3 TRUE 0 12 0 0 0
#> 4 FALSE 12 0 0 0 0
#> 5 FALSE 12 0 0 0 0

#> 8 FALSE 12 0 0 0 0
#> 9 FALSE 12 0 0 0 0
#> 10 FALSE 12 0 0 0 0
#> # … with 13,517 more rows
number of packages that have any problems
stats %>% tally(any)
#> # A tibble: 1 x 1
#> n
#> <int>
#> 1 5901
number of packages that have notes, warnings, errors or failures
stats %>% tally(note > 0)
#> # A tibble: 1 x 1
#> n
#> <int>
#> 1 4985
stats %>% tally(warn > 0)
#> # A tibble: 1 x 1
#> n
#> <int>
#> 1 826
stats %>% tally(error > 0)
#> # A tibble: 1 x 1
#> n
#> <int>
#> 1 820
stats %>% tally(fail > 0)
#> # A tibble: 1 x 1
#> n
#> <int>
#> 1 30
number of packages that don’t have any checks that are ok
stats %>% tally(ok == 0)
#> # A tibble: 1 x 1
#> n
#> <int>
#> 1 2309
wowsers, that’s way more than I would have thought - I hope my packages
aren’t in this group, eek.
emails <- c("myrmecocystus_at_gmail.com", "myrmecocystus_r_at_gmail.com",
"sckott_at_protonmail.com")
me <- bind_rows(lapply(emails, function(z) {
cch_maintainers(z)$data$table
}))
me %>% tally(ok == 0)
#> n
#> 1 0
phew!

Many (7627) have no check problems. Most common is
R code for possible problems
while very uncommon reasons include
PDF version of manual
and
for portable file names

this is the check details you get below the title above

As no surprise, there’s lots of
Malformed Description field: should contain one or more complete sentences
And many
Malformed Title field: should not end in a period.
Classic DESCRIPTION file blues.
I’ve not actually seen this or its variants before:
Dependence on R version ‘3.3.1’ not with patchlevel 0
The award for the longest check string goes to:
m <- arrange(mutate(df, char_count = nchar(output)), desc(char_count))
m$package[1]
