Portal Data Manipulation Pipes (dplyr)

If the file surveys.csv is not already in your working directory then download a copy.

Load the file into R using read_csv().

Use pipes (either |> or %>%) to combine the following operations to manipulate the data.

1. Use mutate(), select(), and drop_na() to create a new data frame with the year, species_id, and weight in kilograms of each individual, with no null weights.
2. Use the filter() and select() to get the year, month, day, and species_id columns for all of the rows in the data frame where species_id is SH.
