Hello friend! Did you just update your R to the latest version and now none of your packages work? Have no fear, lets work on it together:
Update R Packages via the Command Line
To update via the Linuxmachine, use this resource of Ubuntu Cran
For example, to download the latest version of ggplot2 since my updated R gave me a nasty message of
package 'ggplot2' is not available (for R version 3.2.2 I used this link: http://packages.ubuntu.com/trusty/gnu-r/r-cran-ggplot2
You have two choices:
1) Get a highly outdated version of the package:
sudo apt-get install r-cran-ggplot2
2) Or download the package via the Ubuntu Cran website. Make sure to look for .orig.tar.gz for the file name.
Then install with R CMD in your terminal, making sure you remember where you downloaded the folder.
R CMD INSTALL --build r-cran-ggplot2_0.9.3.1.orig.tar.gz
SO. MANY. DEPENDENCIES.
R CMD install works for a hot minute until you need to download a package with a ton of dependencies. Like Caret, which is maintained by Max Kuhn.
Here is the easy solution when you’re done being silly with R CMD INSTALL:
install.packages('package_name', dependencies=TRUE, repos='http://cran.rstudio.com/')
So much easier.
Did your R packages lose their functionality and disappear like a thief in the night when you updated R as well? Is there a way around this?
