Both datasets are divided into many sub-areas, and spatial signatures are derived for each sub-area for each dataset. Next, distances for each pair of areas are calculated. Sub-areas with the largest distances represent the largest change. To reproduce the calculations in the following post, you need to download all of relevant datasets using the code below: library(osfr) dir.create("data") osf_retrieve_node("xykzv") %>% osf_ls_files(n_max = Inf) %>% osf_download(path = "data", conflicts = "overwrite") You should also attach the ...

Part 2: What image format should you use for graphics. Part 3: Including external graphics in your document (this post). Part 4: Optimal {knitr} settings. In this third post, we’ll look at including eternal images, such as figures and logos in HTML documents. This is relevant for all R markdown files, including fancy things like {bookdown}, {distill} and {pkgdown}. The main difference with the images discussed in this post, is that ... Read More
