To accomplish your task, you’ll need to follow these steps: Read in your data into a suitable format (e.g., data.frame). library(rgdal) library(ggplot2) library(dplyr) FDI <- read.csv(“FDI_harmonized.csv”) Drop any rows with missing values in the coordinates columns. coords <- FDI[, 40:41] coords <- drop_na(coords) 2. Convert your data to a spatial frame. ```r coordinates(FDI) <- cbind(coords$oc_lng, coords$oc_lat) proj4string(FDI) <- CRS("+proj=longlat +datum=WGS84 +no_defs +ellps=WGS84 +towgs84=0,0,0") Create a buffer around the original data.
