I',m trying to create an object with name "trainData' and where 'samples_area ' is a shapefile layer with polygons only. I've set the directory to the folder that contains 'samples_area'
trainData <- readOGR("samples_area", "polygons")
Error in ogrInfo(dsn = dsn, layer = layer, encoding = encoding, use_iconv = use_iconv, :
Cannot open data source
Someone, please rectify my mistake.
