spTransform()在R中警告PROJ

Question

我在R v 4.0.4 - sp v 1.4-5，和rgdal 1.5-23。我正在使用rgdal包加载shapefile，然后尝试简单地应用spTransform()，但我得到了一组荒谬的警告，我无法摆脱。有人对此有什么看法吗?

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)

有人遇到过这个并设法压制它吗?

从rgdal找到这个解释:

'GDAL'和'PROJ'库是包的外部，当从源代码安装包时，必须首先正确安装;重要的是，"GDAL"<3 .与'PROJ' <6. 从'rgdal' 1.5-8，安装到'GDAL'>=3， 'PROJ'>=6和'sp'>= 1.4，坐标参考系使用'WKT2_2019'字符串，而不是'PROJ'字符串。
