[R-sig-eco] gis

[Mahnaz Rabbaniha]

Dear all

for doing the gis in R I have done this cod:

library(ggmap)

map=get_map(location=c(lon=50,lat=29), zoom=8,scale = "auto",
maptype=c("satellite"),language = "EN")


this my question, which code is useful for change the *scale = "auto"* for
example: 1: 25000, ?


thanks

mahnaz
