Setup

  • Fork and clone this repo
  • Check out the project structure & files

File path practice

  • We’ll run through each line in the toolik_airtemp_summary.Rmd to understand where it’s pointing, what it’s doing, and add a few more tools to our coding toolkit (readr::read_csv(), janitor::clean_names(), %>%)

  • Similarly, we’ll create from scratch & work through one more exampleto read in another dataset while learning more wrangling skills Our second example will be to:

  • Read in the chlorophyll data

  • Explore the imported data

  • Clean up the dataset names

  • Create a plot of chlorophyll concentration at varying measurement depth, do some customization

  • Export the graph to /figs

Data sources
