Make sure to install the devtools package first.
You will need to install rtools to allow the devtools package to install packages from a remote repository: https://cran.r-project.org/bin/windows/Rtools/. Make sure to update R as well.
Tutorials can be accessed by using the
access_tutorial() function and inserting the tutorial name or “id” as an argument.
An example is shown below
# This code would be used to access the tutorial on Linear Mixed Effects Models ucrstats::access_tutorial("lme_model")
To see the list of all tutorials and their corresponding ids, you can use the
# This code would print out a table of all the tutorials currently available in the package ucrstats::list_tutorials()
These tutorials focus on a few methods commonly used to deal with longitudinal data in R. The tutorials include:
Converting wide data to long (“wide_to_long”)
Introduction to Linear Mixed Effects Models in R (“lme_model”)
Residual Analysis of Linear Mixed Effect Models (“lme_residual”)
