WebMay 13, 2024 · If the text file has an associated x and y location column, then we can convert it into an sf spatial object. The sf object allows us to store both the x,y values that represent the coordinate location of each point and the associated attribute data - or columns describing each feature in the spatial object. WebMay 15, 2024 · If we use this on a data frame it automatically converts the data frame object into a SpatialPointsDataFrame object. An sf object can be created from a data frame in a similarly easy way. We take advantage of the st_as_sf () function which converts any foreign object into an sf object. leaving water in tea kettle
