У меня странная проблема, я не могу обрезать SpatialPolygonsDataFrame , когда я использую определенные экстенты в своем ноутбуке Ubuntu 18.04 с моей версией R 3.6.2, это воспроизводимый пример, где он работает с один экстент, а не другой:
Сначала я загружу пакеты
library(raster)
library(rworldxtra)
Я буду использовать набор данных для стран:
data("countriesHigh")
Теперь я создам 2 различные экстенты:
e1 <- new("Extent", xmin = -87.5, xmax = -27.5, ymin = -60, ymax = 15)
e2 <- new("Extent", xmin = -60, xmax = -27, ymin = -40, ymax = 15)
Теперь, когда я пытаюсь обрезать countryHigh с e1 , я получаю ошибку
SA1 <- crop(countriesHigh, e1)
и следующее сообщение
Error in RGEOSBinTopoFunc(spgeom1, spgeom2, byid, id, drop_lower_td, unaryUnion_if_byid_false, :
TopologyException: Input geom 0 is invalid: Ring Self-intersection at or near point -68.642342900000003 -54.853653260000002 at -68.642342900000003 -54.853653260000002
In addition: Warning messages:
1: In RGEOSUnaryPredFunc(spgeom, byid, "rgeos_isvalid") :
Ring Self-intersection at or near point -68.642342900000003 -54.853653260000002
2: In rgeos::gIntersection(x[i, ], y, byid = TRUE, drop_lower_td = TRUE) :
Invalid objects found; consider using set_RGEOS_CheckValidity(2L)
если я делаю это с экстентом e2 , это работает
SA2 <- crop(countriesHigh, e2)

Я попытался на rstudio.cloud
, и это сработало, это информация о сеансе, я не знаю, что не так с моей версией
