Creating a sliding window with the slider R package to quantify the level of drought (CC239)

Creating a sliding window with the slider R package to quantify the level of drought (CC239) The slider R package has a great set of slide functions to bulid sliding windows across a tidy dataframe. The syntax is very similar to the map functions from purrr. Watch as Pat shows how to quantify the amount of drought using the slide and slide_dbl functions from slider. He'll also compare those functions to the lag and lead fuctions from dplyr. Finally, he makes a plot showing when droughts have occurred over the past 130 years in Southeastern Michigan. He does all this using local weather data downloaded from NOAA in RStudio with a lot of help from the tidyverse You can find my blog post for this episode at https://www.riffomonas.org/code_club/.... #slider #ggplot2 #dplyr #R #Rstudio #Rstats Want more practice on the concepts covered in Code Club?
