TO DOs:

• reduce size of example files
• reduce size of test files
• remove vec.*() functions. No longer needed.
• remove argument cores from functions that do not use terra::app() anymore. Probably all.
• add #' @keywords internal to the documentation of all functions with names starting with "dot"
• check all function examples (mostly update inv.range() arguments). Use devtools::run_examples()
• epm tests should run using a raster instead of using dependency package. Create raster using epm, save script in "data-raw" folder and tiff in "inst/extdata" folder. See: SESraster
• remove rnaturalearth dependency creating custom polygons. See terra::vect()
• add option to compute tree metrics (branch.length, n.descen) from full tree or subset
• organize README according to SESraster
• CRAN like check: devtools::check(remote = TRUE, manual = TRUE)
• organize vignettes and README
• update "hexalogo"
• set up pkgdown website

I tried to run an example of SES code that was feasible. But when I run large data SES, it always goes wrong. null.pd <-rast.pd.ses(data$x, tree, aleats = 3, random = "spat",overwrite=TRUE)
错误: [writeStart] file exists. You can use 'overwrite=TRUE' to overwrite i但是执行overwrite=TRUE后依然显示错误: [writeStart] file exists. You can use 'overwrite=TRUE' to overwrite
