[R-sig-Geo] Add annotation to points using ggmap

Hi group, I printed hdf - get_map(location = c(19.817955, 41.33071), zoom = 14, maptype = 'roadmap') ggmap(hdf, extent = 'normal', maprange = TRUE) + + geom_point(aes(colour = class), data = chkpts) + + theme_nothing() + theme(legend.position = 'right') where data = chkpts is like

[R-sig-Geo] How to plot map with overlay points

Hi group. I have coordinates as in file attached. Trying to print this as points with different colors I follow the commands: al1 = get_map(location = c(41.325997,19.822027), zoom = 10, maptype = 'roadmap') ggmap(al1) + geom_point(data=points, aes(x=lat, y=lon5,colour = type)) The problem

[R-sig-Geo] (no subject)

Hi group, I am stacked in a problem like this. I have a bus stop with known coordinates. I generate in R language distances from this bus stop. Values of these distances are like below (in km) 0. 0.02725136 1.07634471 1.15963225 1.71421571 2.54945626 4.29135102 4.53532958

*destPointRhumb*but still I need some loop function which can print coordinates of points by reading the vector of distances generated in R by some function *dist*.

[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 lonlat 41.00 19.02 but I need to add other sets of points(tables of coordinates) lon

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

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 - Mail original - De: Endri Raco endr...@gmail.com À: r-sig

Re: [R-sig-Geo] R language GIS moving points

Thank you Roman, Using al1 = get_map(location = c(lon, lat), zoom = 6, maptype = 'roadmap') ggmap(al1) + geom_point(data = points,colour=red)+geom_point(data = points2,colour=green) I printed map and points but still thinking about some code to make the points move from one
