zeligDepUpdate {Zelig} | R Documentation |
Compares the packages in Zelig-matrix of dependencies to the
locally installed packages. Finds local packages that have lower
versions than in the corresponding row of the Zelig-matrix.
Also, finds packages that Zelig required but are not
installed locally.
Downloads packages that are locally installed with lower versions and
those from the Zelig-matrix that are not installed.
The download repository is taken from either the default
repos
argument or from the ‘URL’ column of
the Zelig-matrix of dependencies.
zeligDepUpdate(destdir = NULL, installWithVers = FALSE, lib.loc = NULL, repos = "http://cran.r-project.org")
destdir |
directory to store the compress source-codes of packages that are downloaded from web repositories. |
installWithVers |
if TRUE, will invoke the install of the package such that it can be referenced by package version. |
lib.loc |
character vector describing the location of R library trees to search through (and update packages therein). |
repos |
character vector, the base URL(s) of the repositories to use, i.e. the URL of the CRAN master such as "http://cran.r-project.org", which is the default, or its Statlib mirror, "http://lib.stat.cmu.edu/R/CRAN". Can be NULL to install from local zip files. |
No return value.
Installs first level dependencies packages of Zelig using R function
install.packages
with the variable dependencies
set
equal to TRUE. If the installed packages have versions higher than the
corresponding entry in Zelig-matrix, they are reported with a
message. If the R version in the local environment is different from
the R version that Zelig depends on, then, it is reported with a message and no futher action is taken.
