Workshop notes


This workshop is designed to work with RStudio Cloud. Go to (Monash users can log in with their Monash google account) and create a new project. The workshop can also be done using R locally on your laptop (if doing this, we also recommend you create a new project to contain the files).

Running the R code below will download files and install packages used in this workshop.

# Download data

# Install some CRAN packages:
    "tidyverse", "multcomp", "emmeans", 
    "lme4", "lmerTest", "pbkrtest", "BiocManager"))

# Install some Bioconductor packages:

Now load the file linear_models.R in the r-linear-files folder.
