Compute the system requirements (system libraries; operating system packages) required by a set of R packages.
Usage
sysreqs(
packages = NULL,
...,
local = FALSE,
check = NULL,
report = TRUE,
distro = NULL,
collapse = FALSE,
project = NULL
)
Arguments
- packages
A vector of R package names. When
NULL
(the default), the project's package dependencies as reported viadependencies()
are used.- ...
Unused arguments, reserved for future expansion. If any arguments are matched to
...
, renv will signal an error.- local
Boolean; should
renv
rely on locally-installed copies of packages when resolving system requirements? WhenFALSE
,renv
will use https://crandb.r-pkg.org to resolve the system requirements for these packages.- check
Boolean; should
renv
also check whether the requires system packages appear to be installed on the current system?- report
Boolean; should
renv
also report the commands which could be used to install all of the requisite package dependencies?- distro
The name of the Linux distribution for which system requirements should be checked – typical values are "ubuntu", "debian", and "redhat". These should match the distribution names used by the R system requirements database.
- collapse
Boolean; when reporting which packages need to be installed, should the report be collapsed into a single installation command? When
FALSE
(the default), a separate installation line is printed for each required system package.- project
The project directory. If
NULL
, then the active project will be used. If no project is currently active, then the current working directory is used instead.
Details
This function relies on the database of package system requirements
maintained by Posit at https://github.com/rstudio/r-system-requirements,
as well as the "meta-CRAN" service at https://crandb.r-pkg.org. This
service primarily exists to map the (free-form) SystemRequirements
field
used by R packages to the system packages made available by a particular
operating system.
As an example, the curl
R package depends on the libcurl
system library,
and declares this with a SystemRequirements
field of the form:
libcurl (>= 7.62): libcurl-devel (rpm) or libcurl4-openssl-dev (deb)
This dependency can be satisfied with the following command line invocations on different systems:
Debian:
sudo apt install libcurl4-openssl-dev
Redhat:
sudo dnf install libcurl-devel
and so sysreqs("curl")
would help provide the name of the package
whose installation would satisfy the libcurl
dependency.
