Hi, I have a number of spatial weight files and using Roger Bivand's spdep, I would like to

  1. Convert them into neighbor lists using
  2. Convert the neighbor lists into spatial weights

For a given file, the syntax would be

mygal_nb1 <- read.gal("mygalfile1", override.id = TRUE) myweight1 <- nb2listw(mygal_nb1)

I have mygalfile[i] with i from 1 through to 6 and would like to repeat the above two lines through 1 to 6. something like (the syntax below is not correct...just an illustration)

for (i in 1:6) {
mygal_nb[i] <- read.gal("mygalfile[i]", override.id = TRUE) myweight[i] <- nb2listw(mygal_nb[i]
}

Kindly point me in the right direction (whilst read through the material I have)

Ronnie
