我有一个DataFrame,其中包含许多变量,例如百分比,年,公顷等,但是我有一个变量,即距离,我正在评估直接影响(直接影响的区域)以及该影响的程度,其范围为km左右的缓冲区直接的影响,我将其与对照进行比较。我有:
至此,我的变量是分类的,即使它们代表距离。
Distances:"dirImpct",1km","2km","3km","4km","5km","6km","7km","8km","9km","10km","20km","30km","40km","50km","60km","70km", "controle")
我想要这样的东西:
Distances: dirImpct < km < control
DirImpact= distance 0
km= distances, (1,2,3,4,5,6,7,8,9,10,20,30,40,50,60,70)
control= distances > 70
您可以转换为factor
并重命名levels
。
