This is the public repository for "Climate warming amplifies the frequency of fish mass mortality events across north temperate lakes" in Limnology Oceanography Letters. The R code is partitioned into 7 RMarkdown files that perform discrete steps (e.g., compile data, run models, create figures).
All data files necessary to perform analyses are available as releases associated with this project. There are 7 releases that each contain discrete groups of files that are under the 2 GB file size limit for releases (e.g., raw data, processed data, models).
If you have any problems running the code, please contact me at simontye@uark.edu and I will help as best I can. Below are brief descriptions of each RMarkdown file.
Combines Minnesota and Wisconsin fishkill datasets, then collates local environmental covariates. After running this script, the historical (2003-2013) and future (2041-2059; 2081-2099) dataframes are saved as df_historical.csv and df_future.csv, respectively.
Partitions data into training and testing sets.
Compares preliminary models from 3 model families:
- Logistic regression
- Ridge regression
- Lasso regression
Compares preliminary models.
Runs best fit models.
Performs statistics.
Creates figures.
