Backup and Restore Certain CRAN Package Versions
Create a snapshot of your installed CRAN packages with 'snap', and then use 'restore' on another system to recreate exactly the same environment.
devtools::install_github("mangothecat/pkgsnap")library(pkgsnap)For this experiment we create a new library directory, and install
some packages there. We will then remove this directory entirely,
and recreate it using pkgsnap.
lib_dir <- tempfile()
dir.create(lib_dir)We make this new library directory the default:
.libPaths(lib_dir)The new library directory is currently empty:
installed.packages(lib_dir)[, c("Package", "Version")]#> Package Version
Let's install some packages here. Note that the dependencies of these packages will be also installed.
install.packages(c("testthat", "pkgconfig"))#> Installing packages into '/private/var/folders/ws/7rmdm_cn2pd8l1c3lqyycv0c0000gn/T/RtmpOssfTB/file1003d2f2dd0b1'
#> (as 'lib' is unspecified)
#> also installing the dependency 'praise'
#>
#> Package which is only available in source form, and may need
#> compilation of C/C++/Fortran: 'testthat'
#>
#> The downloaded binary packages are in
#> /var/folders/ws/7rmdm_cn2pd8l1c3lqyycv0c0000gn/T//RtmpOssfTB/downloaded_packages
#> installing the source packages 'praise', 'testthat'
installed.packages(lib_dir)[, c("Package", "Version")]#> Package Version
#> pkgconfig "pkgconfig" "2.0.0"
#> praise "praise" "1.0.0"
#> testthat "testthat" "0.11.0"
We will now create a snapshot, and then scrap the temporary package library.
snapshot <- tempfile()
snap(to = snapshot)
read.csv(snapshot)[1:5,]#> Package Version Source Link
#> 1 R 3.3.0 R NA
#> 2 pkgconfig 2.0.0 cran NA
#> 3 praise 1.0.0 cran NA
#> 4 testthat 0.11.0 cran NA
#> 5 BiocInstaller 1.21.3 bioc NA
unlink(lib_dir, recursive = TRUE)Create a new package library.
new_lib_dir <- tempfile()
dir.create(new_lib_dir)
.libPaths(new_lib_dir)Finally, recreate the same set of package versions, in a new package library.
