[R-sig-Geo] Represent data on map

[Rolando Valdez]

Hi,

I'm trying to represent data (unemployment rate) on a map. 

This is what I have:

> library(sp)
> library(maptools)
Checking rgeos availability: TRUE
> map <- readShapeSpatial("ESTADOS")
> read.csv("C:\\Users\\Rolando\\Documents\\Maestría en Economía\\3er Semestre\\AEMT\\desempleo_est.csv")
> spplot(map, c("2000"))
Error en `[.data.frame`(obj at data, zcol) : undefined columns selected

> unem <- read.csv("C:\\Users\\Rolando\\Documents\\Maestría en Economía\\3er Semestre\\AEMT\\desempleo_est.csv")
> names(unem)
[1] "num_est" "est"     "X2000"   "X2005"   "X2010"   "X2013"

I hope you can help me, this is my first time in R.

Regards,

Rol~
