Fixing an error in plotting a gpx file using ggplot2 in R
I'm attempting to create a map showing a series of gpx files using ggplot2. Most of the gpx files work a treat, but some of them throw up some errors where what is plotted is a solid shape instead of a line. I've included one such example below. The plot in base R shows what the result should look like.
I'm not entirely sure what the source of the ggplot2 error is, any ideas would be much appreciated.
The gpx file used below can be downloaded (from Strava) [here] (a subset of the dataframe showing a less extreme version of the error) is pasted below1.
The code I'm using is:
library(rgdal)
library(raster)
library(dplyr)
library(ggplot2)
gpxFile <- "file.gpx"
gpxRoute <- readOGR(dsn = gpxFile, layer = "tracks")
## PLOT USING BASE R
base_plot <- plot(gpxRoute)
## PLOT USING GGPLOT2
gg_plot <- gpxRoute %>%
fortify() %>%
ggplot() +
geom_line(aes(x = long, y = lat, group = group, colour = "red"))
gg_plot
Base R result
ggplot result
long lat order piece id group

Here is a solution. The reason why you ended up seeing the ggplot graphic is that you used geom_line(). geom_line() connects data points in order of the variable on the x axis. The reason why you see a polygon is that there are a bunch of vertical lines going up and down along the x-axis, and we perceive that area is filled, I think.
# geom_line() connects them in order of the variable on the x axis.
# I called your subsetted data mydata.
ggplot() +
geom_line(data = mydata, aes(x = long, y = lat, group = group), colour = "red")
Now I use geom_path() and see the route. One more thing. You want to have color outside of aes() in this case.
ggplot() +
geom_path(data = mydata, aes(x = long, y = lat, group = group), colour = "red")
