Exercise 16
In Exercise #14, I created 4 separate Data Objects of mean, sd, min, and max of male grouse by year within lek complex. Add n (number of samples) per year and complex combination as well. Merge these into single data object, and export as a .csv file.
Exercise 17
Write a loop that:
• feeds multiple statistical functions (i.e., mean, sd, length) to;
• multiple variables (elev, slope, aspect);
• by presab (see Exercise #15) in the data bearclawpoppy.csv; and
• exports these as 3 R objects in your workspace
• Write a loop to read in the 4 m1.csv,…,m4.csv datasets
Challenges:
• How to change the m*.csv, i.e., filename) in each loop?
• How to ensure each new object is assigned a unique name (e.g., m1,…,m4)?
Exercise 18
Write a function – say AnnualLekSummary – that:
Imports the lek data (assume it has been "cleaned");
Selects from the data a specified year for which statistics are desired;
Calculates mean, 2SD, n, and 90%CI for the specified year within lek complex
Writes the yearly-based output as a separate *.csv file
