Simulated development time code

This file includes: 1) Code for data extraction of development times from Figure 3 of Carroll et al 1997; note that the exact pixel values will differ depending on how you size and crop the image. 2) Code for simulating 1000 (or however many you want) datasets using the means and standard deviations of 1988 and 2013-2014 data. 3) Code for statistical comparison of all 1000 datasets for the complete dataset and within each host plant. Code for model selection is not included (but could be added if requested).
