Given the names of packages published on CRAN, return the output of checks that return notes, warnings or errors.
character vector of the names for the packages on CRAN
if "website"
the data is scrapped from the CRAN
website, if "crandb"
the data is downloaded from a RDS
file hosted on the CRAN servers (which is used to generate the
information found on the CRAN website).
additional arguments to control where the data from the check results are coming from and how they are downloaded from the CRAN servers (see Details section).
an object created by cran_details
Should the messages of the “Check Details” be printed? (logical)
if TRUE
the summary method will print a "all clear"
message for package(s) that have an OK status for all CRAN checks.
a tibble
listing the names of the packages that have non- OK
check results, the nature of the result (WARN
, ERROR
,
FAIL
, NOTE
, or other issues).
Where does the data come from?
The data comes from the CRAN servers. They generate RDS files that contains information regarding the results of the checks for all the packages, and all the flavors. This data is then used to generate the web pages.
foghorn
provides access to either of these data sources. If
you choose src = "website"
the data is scrapped from the
CRAN website. If you only need to check a few packages, this is a
good option. If you choose src = "crandb"
the RDS files
(about 20Mb) are downloaded first from the CRAN servers.
When choosing src = "crandb"
you can also specify the
following options:
dest a folder where to store the RDS files (tempdir()
by default).
protocol either https
(default) or http
.
overwrite when FALSE
(default), if the file exists in
dest
then it will not be downloaded again. When
TRUE
the file gets downloaded every time it's
needed.
Note that the tools
package contains unexported
functions that can be used to extract summary information from
the check results. Specifically
tools:::sumarize_CRAN_check_status
is similar to
show_cran_results
.
