Codes from the analyses on spatial patterns of tree mortality across Amazonian forests published in the article Esquivel-Muelbert et al. (2020) Tree mode of death and mortality risk factors across Amazon forests. Nature Communications 10.1038/s41467-020-18996-3

Code developed and tested using the R statistical platform R v 3.5.2 (R Development Core Team, 2015).

01_Master.R

Describes the analyses shown in the paper including plot-level analyses and the survival analyses (tree-level)

Codes for Figures 1, 2 and 3 are provided here

02_functions_plot_level.R

Functions used to perform plot-level analyses and plot Figures 1 and 2

03_functions_survival_analyses.R

Functions used to perform survival analyses and plot Figure 3
