Hi - I'd appreciate any suggestions as to how I can superimpose numbers over the coloured symbols I've plotted on a google map using the code below. The numbers I want to use as labels are in the 1st column of the table. I've seen a couple of solutions online, but neither has worked for me. ..........
library(ggplot2) library(ggmap) Rangitikei <- read.table(text="number lon lat 11 175.74 -39.55 10 175.72 -39.65 9 175.97 -39.7 8 175.78 -39.81 7 175.67 -39.84 6 175.894 -39.84 5 175.96 -39.85 4 175.60 -39.90 3 175.37 -39.905 2 175.53 -39.96 1 175.60 -39.99", header = TRUE, strip.white = TRUE) # Get the map RangitikeiMap <- get_googlemap(center = c(lon = 175.736, lat = -39.8), maptype='roadmap', zoom=10) # Plot the points on the map ggmap(RangitikeiMap) + geom_point(data=Rangitikei, aes(x=lon, y=lat), colour="gold2", size=6, alpha=.7) .........
