## Monocle3 dependancies
BiocManager::install(c("Biobase", "SingleCellExperiment", "batchelor", "BiocGenerics", "DelayedArray", "DelayedMatrixStats", "limma", "S4Vectors", "SummarizedExperiment", "pcaMethods"))

remotes::install_github('cole-trapnell-lab/leidenbase')
remotes::install_github('cole-trapnell-lab/monocle3')

## Test out the installation
library(monocle3)

## Mac users may also experience installation problems due to Xcode or gfortran.
## Instructions: https://cole-trapnell-lab.github.io/monocle3/docs/installation/

# If you had issues with leidenbase and gfortran, trying downloading and installing a newer gfortran
# https://gcc.gnu.org/wiki/GFortranBinaries

## Possible you may have to install Rtools if the above fails
