This package provides a Shiny application used for diagnosis of cognitive status based on neuropsychological scores.

Installation

You can install the development version of ntrd from GitHub with:

# install.packages("pak")
pak::pak("rmtrane/ntrd")

# install.packages("remotes")
remotes::install_github("rmtrane/ntrd")

Note that some features of the application mean additional resources. For example, the R package REDCapR is necessary to be able to pull data straight from REDCap. To install the packages needed to enable all features, use

pak::pak("rmtrane/ntrd", dependencies = TRUE)

remotes::install_github("rmtrane/ntrd", dependencies = TRUE)

Example

You can start the application as follows:

library(ntrd)
shinyDashboard()

Alternatively, the app is also available as an RStudio add-in. I.e., once the package is installed, you should be able to launch it from the RStudio add-in dropdown menu:
