# install.packages("pak") # uncomment and run this line *once*
# options(use_bioconductor = FALSE) # do this is you get some issues running the next line when connected to the eduroam network
pak::pkg_install("ISCAM4/ISCAM") # this installs or updates the package

# if {pak} doesn't work, uncomment and run the following two commands
#install.packages("remotes")
#remotes::install_github("ISCAM4/ISCAM")

# the following loads the package. You need to do this every time you want to use ISCAM functions
library(ISCAM)

This package collates and presents functions for ISCAM alongside some data to be used alongside the textbook.

If you don't know how a function e.g. EXAMPLE() works, you can write ?EXAMPLE in the console to get help. You can also find it on the website. Also look to the textbook/Canvas/homework to see how the function is used.

You can load the workspace by running

load(url("http://www.rossmanchance.com/iscam4/ISCAM.RData"))
