Hi,
I'm trying to plot a map with the location of the stations that I am using
require(MASS)require(maps)
mapaBrasil <- read.table("BASE_BR.txt",sep="")
latlonRS <- read.csv2("coordenadas.txt",h=F,sep="")

png(filename="mapa_grupos.png",width=600,height=800)
# criating a map for RSmap(xlim=c(-80,-35),ylim=c(-45,10), type="n")map.axes()
# plot a  maplines(mapaBrasil[,2], mapaBrasil[,1])
# plot stationspoints( latlonRS[,2], latlonRS[,1], pch=membros)
dev.off()
datas:
     V1     V21 -33.51 -53.352 -30.83  -55.63 -29.45  -51.84 -29.68 -51.055 -29.05 -50.136 -31.78 -52.417 -32.03  -52.18 -30.53 -52.51
and the ERROR IS:
Carregando pacotes exigidos: MASSCarregando pacotes exigidos: mapsErro em plot.xy(xy.coords(x, y), type = type, ...) :   objeto 'membros' não encontrado
