spChFIDs-methods: change feature IDs in spatial objects

Description

When the feature IDs need to be changed in SpatialLines* or SpatialPolygons* objects, these methods may be used. The new IDs should be a character vector of unique IDs of the correct length.

Arguments

Methods

obj = "SpatialLines", x = "character"
replace IDs in a SpatialLines object
obj = "SpatialLinesDataFrame", x = "character"
replace IDs in a SpatialLinesDataFrame object
obj = "SpatialPolygons", x = "character"
replace IDs in a SpatialPolygons object
obj = "SpatialPolygonsDataFrame", x = "character"
replace IDs in a SpatialPolygonsDataFrame object

# xx1 <- spChFIDs(xx, as.character(xx$CNTY_ID))
# row.names(as(xx1, "data.frame"))
