如何将 python 中生成的 MultiLineString 转换为 R 对象?
How to transform MultiLineString produced in python to R object?
我正在使用 reticulate
包在 R 代码中集成一个 python 函数,python 中的原始输出是 MultiLineString。
Class Rstudio 中的输出是:
> class(result)
[1] "centerline.geometry.Centerline" "shapely.geometry.multilinestring.MultiLineString"
[3] "shapely.geometry.base.BaseMultipartGeometry" "shapely.geometry.base.BaseGeometry"
[5] "python.builtin.object"
> typeof(result)
[1] "environment"
Rstudio 中的输出:
> result
MULTILINESTRING ((188.84310143 -25.44115933212567, 189.0883871453183 -25.39224242194983),
(189.34310143 -25.40412148482432, 189.0883871453183 -25.39224242194983))
我是 python 的新手,有什么方法可以在 python 或 R 中传输输出,以便我可以使用它来制作 Spatiallines 或 SF 对象?
#output of python function in R
> class(result)
[1] "centerline.geometry.Centerline" "shapely.geometry.multilinestring.MultiLineString"
[3] "shapely.geometry.base.BaseMultipartGeometry" "shapely.geometry.base.BaseGeometry"
[5] "python.builtin.object"
> typeof(result)
[1] "environment"
#Convert from Python to R object
processed <- reticulate::py_to_r(result)
#change type from environment to character
result_2<-type.convert(processed,as.is = TRUE)
#read WKT and construct SpatialLines
x<-readWKT(result_2)
> x
class : SpatialLines
features : 1
extent : 187.6103, 191.6382, -25.8519, -24.55464 (xmin, xmax, ymin, ymax)
crs : NA
