This dataset was used to collect and analyze data for the MPhil Thesis, "Lithic Technological Change and Behavioral Responses to the Last Glacial Maximum Across Southwestern Europe." This dataset contains the raw data collected from published literature, and the R code used to run correspondence analysis on the data and create graphical representations of the results. It also contains notes to aid in interpreting the dataset, and a list detailing how variables in the dataset were grouped for use in analysis. The file "Diss Data.xlsx" contains the raw data collected from publications on Upper Paleolithic archaeological sites in France, Spain, and Italy. This data is the basis for all other files included in the repository. The document "Diss Data Notes.docx" contains detailed information about the raw data, and is useful for understanding its context. "Revised Variable Groups.docx" lists all of the variables from the raw data considered "tool types" and the major categories into which they were sorted for analysis. "Group Definitions.docx" provides the criteria considered to make the groups listed in the "Revised Variable Groups" document. "r_diss_data.xlsx" contains only the variables from the raw data that were considered for correspondence analysis carried-out in RStudio. The document "ca_barplot.R" contains the RStudio code written to perform correspondence analysis and percent composition analysis on the data from "R_Diss_Data.xlsx". This file also contains code for creating scatter plots and bar graphs displaying the results from the CA and Percent Comp tests. The RStudio packages used to carry out the analysis and to create graphical representations of the analysis results are listed under "Software/Usage Instructions." "climate_curve.R" contains the RStudio code used to create climate curves from NGRIP and GRIP data available open-access from the Neils Bohr Institute Center of Ice and Climate.
