How to plot shapefile in R

Question

I am trying to plot a shapefile on top of a raster using the command readOGR. My current code is:
    CEZ <- readOGR(".", "Shapefile/CEZ1")

This is followed by the error code

Error in ogrInfo(dsn = dsn, layer = layer, encoding = encoding, use_iconv = use_iconv,        :
Cannot open data source

I am unsure what this code means - Is it a problem with the shapefile, the command or the way I have structured the path?

The raster package has a handy wrapper function for reading shapefiles. You should be able to do:
library(raster)
CEZ <- shapefile("./Shapefile/CEZ1.shp")

if that's where your shapefile really is. You might get a better error message.
