[R-sig-Geo] spplot help, please

[Ákos Bede-Fazekas]

Dear Marvin,
second argument of substring() is wrong. Change it from 14 to 9:
> GA$names <- substring(GA$names, 9, nchar(GA$names))
> match(cntys, GA$names)
  [1]   1   2   3   4   5   6   7   8   9  10  11  12  13  14  15  16  17
18
 [19]  19  20  21  22  23  24  25  26  27  28  29  30  31  32  33  34  35
