RLAB

R-LAB (R for Lifestyle and Brain Health) is a collaborative learning space designed for early career researchers (ECRs) with a shared interest in lifestyle interventions, brain health, Alzheimer’s disease, and Down syndrome. The lab focuses on advancing applied R programming skills relevant to real-world data challenges in health research.

Through hands-on workshops, code walkthroughs, and peer-driven projects, R-LAB empowers ECRs to go beyond basic statistical routines and build confidence in data wrangling, visualization, reproducible reporting, and advanced modeling techniques—all within the context of lifestyle and neurodegenerative research.

The goal of R-LAB is to foster a supportive community where emerging scientists can sharpen their programming skills, enhance their research rigor, and accelerate their contributions to the field.

Installation

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

# install.packages("devtools")
devtools::install_github("bhelsel/RLAB")

Render a Presentation

To render a presentation, there is a utility function called render_presentation

library(RLAB)
# Set your output directory to the location you want the presentation stored
# The function will create the folder if it does not exisit
outpath <- "full/path/to/your/output/directory"
render_presentation(outdir = outpath, name = "02")

The name argument uses matching via regular expressions, so it can be 02 or the full name 02-AdvR-Names-Values.

The list of completed presentations include:

• 01-R-Basics
• 02-AdvR-Names-Values
• 03-AdvR-Vectors
• 04-AdvR-Subsetting
• 05-AdvR-Control-Flow
• 06-AdvR-Functions

Hex Sticker

This is code used to generate and download the Hex sticker after the package is installed. Change the file name if you want to save it in a different location

hexSticker::sticker(
  system.file("images/brain.png", package = "RLAB"),
  s_x = 1,
  s_y = 0.9,
  s_width = 0.65,
  s_height = 0.65,
  package = "RLAB",
  p_size = 40,
  p_y = 1.5,
  filename = "man/figures/RLAB.png",
  h_color = "#2a5dab",
  h_fill = "#3E3D55",
  p_color = "#fed707",
  p_family = "sans",
  p_fontface = "bold",
  url = "https://www.github.com/bhelsel/RLAB",
  u_color = "#fed707",
  u_family = "sans",
  u_size = 8.75,
  dpi = 600
