從本地源更新特定的R軟件包

Question

我已將R安裝在沒有互聯網訪問的機器上。是否可以從本地源檔案更新特定的軟件包？什麼是正確的做法？

Answer 1

install.packages(pkgs, lib, repos = getOption("repos"), 
       contriburl = contrib.url(repos, type), 
       method, available = NULL, destdir = NULL, 
       dependencies = NA, type = getOption("pkgType"), 
       configure.args = getOption("configure.args"), 
       configure.vars = getOption("configure.vars"), 
       clean = FALSE, Ncpus = getOption("Ncpus", 1L), 
       verbose = getOption("verbose"), 
       libs_only = FALSE, INSTALL_opts, quiet = FALSE, 
       keep_outputs = FALSE, ...) 

使用上述命令。如需更多幫助，請參閱https://stat.ethz.ch/R-manual/R-devel/library/utils/html/install.packages.html
