ggplot(data = mpg) +
geom_point(mapping = aes(x = displ, y = hwy))
- I thought it might be educational to do the identical graph with my dataset of instagram vancouver photos January 1-31, 2016 average colours:
data4 = read.csv(
file = # 
stringsAsFactors = F)
ggplot(data=data4)+geom_point(mapping = aes(x = hour, y=colour))
-  I believe you can read from a URL (on github or anywhere!) directly so the following should work too:
- Here’s how it looks:
- What was I trying to do? I was trying to plot average colour versus hour i.e. 0-23!
- Why is it a mess? Because no two average colours are identical so you have 146475 values on the y axis which won’t fit on any display less than 146475 pixels high :-). Well not unless you have the world’s largest screen!
- Part 2 will explore changing the colours to the 600 or so R colours.
