[英]Converting polygon to sf in R
Using the tutorial here: https://www.r-spatial.org/r/2018/10/25/ggplot2-sf-2.html (in the section called "States (polygon data)"), I'm trying to convert polygons to an sf object.使用这里的教程: https://www.r-spatial.org/r/2018/10/25/ggplot2-sf-2.html (在名为“状态(多边形数据)”的部分),我正在尝试将多边形转换为 sf object。
library("maps")
states <- st_as_sf(map("state", plot = FALSE, fill = TRUE))
head(states)
I get the error message: Error in as_mapper(.f, ...): argument ".f" is missing, with no default
我收到错误消息:
Error in as_mapper(.f, ...): argument ".f" is missing, with no default
Thank you in advance!先感谢您!
Looks like it's confusing map()
from the purrr
package with map()
from the maps
package.看起来它混淆了
purrr
package 中的map()
map()
maps
package 中的 map()。 Try:尝试:
states <- st_as_sf(maps::map("state", plot = FALSE, fill = TRUE))
