dillonma

#(so you could modify the relationships as well and create a completely new shapefile)

library(rgdal)
## read "/path/to/files/filename.shp"
shp <- readOGR("/path/to/files/", "filename")  

## add new attribute data (just the numbers 1 to the number of objects)
shp$new.att <- 1:nrow(shp)

## write out to a new shapefile

dillonma

library(foreign)
dbfdata <- read.dbf("file.dbf", as.is = TRUE)
## add new attribute data (just the numbers 1 to the number of objects)
dbfdata$new.att <- 1:nrow(shp)

## overwrite the file with this new copy
write.dbf(dbfdata, "file.dbf")
