Description

@gafo25

Suggested changes:

  • Add package requirements in README file. The gradethis package needs to be installed from github because of R 4.4.2 PWB compatibility
    • install.packages("reticulate")
    • devtools::install_github("rstudio/gradethis")
  • Add Python venv creation in README file. You can link my repo https://github.com/Public-Health-Scotland/vscode_prep
  • You need to create your Python venv environment. Remember the name and path location
  • Specify your Python version and package ones too (For compatibility purposes) e.g. pip install pandas==2.3.1
  • Change the logo for a png with transparent background (to be compatible with dark mode). You can do for the other images too
  • Remove all the install.packages comments from intro.Rmd. They should be in README
  • You need to use Sys.unsetenv("RETICULATE_PYTHON") in your intro.Rmd r setup chunk before library(reticulate). I noticed reticulate has been set as a environment variable (ONLY for PWB). If you will publish on shiny app you need to comment that line.
  • You have to use reticulate to create your Python environment (PWB or shiny app). This package will detect if it is already created and skip the creation.
# Sys.unsetenv("RETICULATE_PYTHON")
library(learnr)
library(gradethis)
library(reticulate)

knitr::opts_chunk$set(echo = FALSE)

tutorial_options(
  exercise.checker = gradethis::grade_learnr
)

reticulate::virtualenv_create(envname = "pyenv")
reticulate::virtualenv_install("pyenv", packages = c("pandas==2.3.1"))
reticulate::use_virtualenv("pyenv", required = TRUE)
  • You can add dark theme feature for accessibility purposes. You have to modify your CSS file and add these lines of code at the button part. A CSS file has the capability to detect your browser windows theme preference. You have to add the rest of your CSS elements depending on the theme light/dark.
@media (prefers-color-scheme: dark) {
  body {
    background-color: #121212;
    color: #ffffff;
  }
}

@media (prefers-color-scheme: light) {
  body {
    background-color: #ffffff;
    color: #000000;
  }
}
