Yeah, you're putting together a string, not actually running any commands.
Does this not work:
for (i in (1:length(names( spatialPolygonDataFrame)))){
spatialPolygonDataFrame$names(spatialPolygonDataFrame@data[i]) <-
as.character( spatialPolygonDataFrame$names(
spatialPolygonDataFrame@data[i]))
}
Subsetting on a variable should work just fine. I don't see any need for
paste().
