Multiple datasets with coordinates

Hi,
This worked for me but I only tried with ggplot:

1?) add a colum "$type" to your differents dataset to discriminate them
2?) join then your datasets in one dataframe (rbind)
3?) then in ggmap use "fill=type", so as: ggmap(al1) + geom_point(data=points, aes(size = 4, fill=type))

Hope it works,

Kevin

Objet: [R-sig-Geo] Multiple datasets with coordinates

Hi group,
Trying to plot with ggplot2 different datasets of coordinats inside the
same chart.

Till now I can plot

ggmap(al1) + geom_point(data=points,colour="red", size = 4)

where points are tables



lon    lat

41.00   19.02


but I need to add other sets of points(tables of coordinates)


lon    lat

41.00   19.02

...     .....
*

with other colors in the same chart.Is that possible?
