Removing outliers in R with tools from dplyr and ggplot2 (CC232)

If you know you have outliers in your dataset how would you go about removing them in R? In this episode, Pat will show you how to identify outliers using graphical approaches using ggplot2 with geom_histogram and geom_line. If they are truly anomalous we remove them using functions from dplyr like filter, mutate, if_else, and drop_na. We'll do all this using local weather data from the NOAA website in RStudio You can find my blog post for this episode at https://www.riffomonas.org/code_club/.... #ggplot2 #dplyr #R #Rstudio #Rstats Want more practice on the concepts covered in Code Club?
