dplyr exercises

For these exercise download and import the data files containing my Ebird observations from here: https://github.com/mbtoomey/Biol_7263/blob/main/Data/MBT_ebird.csv?raw=true

Using the functions in dplyr and base R answer the following questions. Create an R markdown file that documents the answer and the code you used to answer the question. In the markdown also include a link to the commented R script where all of the code can be run to reproduce your answers. Knit this to an html file and link on your portfolio page.

  1. In which year did I observe the most individual birds? How many?

  2. In that year how many different species of birds did I observe?

  3. In which state did I most frequently observe Red-winged Blackbirds?

  4. Filter observations for a duration between 5 and 200 minutes. Calculate the mean rate per checklist that I encounter species each year. Specifically, calculate the number of species in each checklist divided by duration and then take the mean for the year.

  5. Create a tibble that includes the complete observations for the top 10 most frequently observed species. First generate a top 10 list and then use this list to filter all observations. Export this tibble as a .csv file saved to a folder called “Results” folder within your R project and add link to the markdown document.
