我使用的是 R v 4.0.4 - sp v 1.4-5 和 rgdal 1.5-23。我正在使用 rgdal 包加载一个 shapefile,然后尝试简单地应用 spTransform(),但我收到了一系列荒谬的警告,无法摆脱。有人对此有什么见解吗?
options("rgdal_show_exportToProj4_warnings"="none")
library(rgdal)
library(sp)
## Shapefile has a projection of WGS84
X <- readOGR(dsn=".", layer="myshapefile.shp")
UTM30 <- sf::st_crs(32630)$proj4string
transf <- spTransform(X,UTM30)

有人遇到过这个问题并解决了吗?
谢谢!
