s <- states() in illinois mapping #3

Closed Chuan1997 closed 1 year ago

Chuan1997 commented 1 year ago

Hi, there! I try to learn the details of coding a population map and when I run the illinois code, this error occured:

map <- "illinois"
data <- st_read(".../kontur_population_US_20220630.gpkg")
s <- states() |> st_transform(crs = st_crs(data))

_Retrieving data for the year 2021 |======================================================================================================================| 100% Error: Cannot open "C:\Users\xxx\AppData\Local\Temp\RtmpWcYtrq"; The source could be corrupt or not supported. See st_drivers() for a list of supported formats._

Any idea what happened? Much appreciated if you could help!

Is your second line of code running without error? In other words, are you successfully reading in the Kontur data?

turns out I need to put options(tigris_use_cache = TRUE) in the beginning of the file, and the error is gone. And now the question is anyone locate outside the U.S. cannot use states() function to download, so I will try to use other countries to continue the learning of rayshader. Thanks!
