Getting a map with points, using ggmap and ggplot2 I want a map with points (and other geom_* layers) on it I get the map, but instead of the points all I get is a warning: Message d'avis : Removed 3 rows containing missing values (geom_point) H
Add scalebar and north arrow in a ggmap without using ggsn CY_map <- get_stadiamap(cy, zoom = 10, maptype = "stamen_terrain") %>% ggmap() which creates a "gg" "ggplot" object called CY_map (note: I have used get_stadiamap instead of get_stamenmap since the latter is not supported now However, the important thing is that a gg object is present) Then, I combined the gg object with ggplot:
r - Adding geom_point to ggmap (ggplot2) - Stack Overflow gg <- gg + geom_map(data=ddf, map=wrld, aes(map_id=Country, fill=x1), color="white", size=0 25) I want to add geom_point to each one of these countries, and set the size of the geom equal to my x2 variable
r - World map with ggmap - Stack Overflow I am using ggmap and wish to have a map of the world centered on Australia to which I can easily plot geocoded points ggmap seems to be a lot easier to use compared to some of the other mapping pa
Layering a ggplot2 map onto ggmap satellite with bathymetry data gg <- gg + coord_map() + theme_classic() However, I get the error: Error: ggplot2 doesn't know how to deal with data of class ggmapraster when I try and run the fortify code I have used this method before to add bathymetry polygons (see previous question) but they looked messy when I plotted datapoints onto the ocean so I am now trying this
ggmap, ggimage. . . - Saving and loading maps in R - Stack Overflow An ideal solution should minimize the amount of code between get_map() (or a related command) and using the saved map within ggmap() (or a related command) I know already that get_map() has a filename attribute to save maps as an image, and I also know the ggimage() method (I've never actually worked with it, though )
Pacific-centric Robinson projection with ggplot in R gg You can use gdalUtils for this as well, but it just calls the system binaries and you have to specify the clipping polygons with well known strings (so the system call is a few characters shorter for the line)
vim: how to map gg=G in insert mode - Stack Overflow Can someone tell me how to map gg=G in insert mode When I use map <F2> <C-O>gg=G the cursor is correctly set to the beginning of the file but I then get =G inserted
