shiny-nonlinear is a tool to test if (one or more) predictor variables in a standard regression model have a non-linear relationship with the outcome, using natural cubic splines.
This app uses the packages shinyBS, stringr, splines, foreign, survival and lmtest, which need to be installed before the app can be used.
The packages can be installed with the following syntax:
# check if necessary packages are installed and install if not
need_packages <- c("stringr", "splines", "foreign", "survival", "lmtest", "shiny", "shinyBS")
new_packages <- need_packages[!(need_packages %in% installed.packages()[, "Package"])]
if (length(new.packages) > 0) install.packages(new_packages)To download and run this app directly you can then use:
shiny::runGitHub("shiny-nonlinear", "NErler")
