hydroTSM降雨量插值

Question

我正在尝试使用hydroTSM软件包使用R-studio中的8个雨量站的IDWrainfall数据进行插值。一切都很顺利，直到最后一点，我得到了下面的错误。我不能理解它的意思。有人能帮上忙吗？

xL.idw <- hydrokrige(x.ts= RAINFALLDATA, x.gis=EbroPPgischanged,
+                     X="EAST_ED50", Y="NORTH_ED50", sname="ID",
+                     bname="CHE_BASIN",
+                     type= "block",
+                     subcatchments= lowaat_catchments,
+                     cell.size= 3000,
+                     ColorRamp= "Precipitation")

这是由"sp“包中的变化引起的错误。我们必须等待来自hydroTSM的新更新。
