我正在尝试加载一个zip级别的shapefile来做一些绘图,按:https: //github.com/hadley/ggplot2/wiki/plotting-polygon-shapefiles http://www.nceas.ucsb.edu/scicomp/ usecases/ReadWriteESRIShapeFiles等

我的代码:

library(rgdal)
library(RColorBrewer)
library(ggplot2)
zipmap = readOGR(dsn="file.zip/", layer="myZIPmap")

我收到这个错误:

Error in ogrInfo(dsn = dsn, layer = layer, input_field_name_encoding = input_field_name_encoding) : 
  Cannot open file

我检查了驱动程序,但说实话,我无法解释输出:
