Why write functions

• increase code readability (give them clear names)
• only need to update code in one place
• reduce chance of copy/paste errors

When to write a function Generally, whenever you've copied/pasted a block of code more than 2x, though an argument can be made that turning code into functions to make it more readable is great whenever

Words of Wisdom Always new techniques/better ways of approaching problems. This workshop is only an intro to get you started

Ideas

• write function to wrangle LTER temp data & function to plot (old work from grad school that needs some serious help but could be used as inspo: https://github.com/stier-lab/Csik-etal-Functional-Ecology/blob/master/code/01_LTER_temps.Rmd)
• example plot output (averaged across years, but could have function that produces one plot per year: https://www.frontiersin.org/files/Articles/1072807/fmars-10-1072807-HTML/image_m/fmars-10-1072807-g001.jpg)

• what are functions / basics
• simple example function (convert temp-style example, though that one is overused...)
• fxn to wrangle data
• fxn to plot data
• option: iterate over multiple datasets to wrangle & plot using fxns with a for loop
• shiny fxns (ui & server)
