3. Github installation
Use the "install_github()" function in the devtools package to install.
library(devtools)
install_github("schymane/ReSOLUTION")4. Manual installation
For some packages that are difficult to install, or packages that report errors, we can choose to install them manually. Here are two typical examples
1 BiocManager::install("org.Hs.eg.db")
For example, for this package, we manually downloaded the installation package from the wrong address
https://bioconductor.org/packages/3.13/data/annotation/src/contrib/org.Hs.eg.db_3.13.0.tar.gz
Then install it manually
install.packages("~/R/org.Hs.eg.db_3.13.0.tar.gz", repos = NULL, type = "source")
2 devtools::install_github("iaconogi/bigSCale2")
Download the installation package according to this address, and then install it manually. If the installation is unsuccessful, check the error message. If some dependencies are not installed, install these dependencies and then reinstall the initial package.
