Big picture: I don't think it's very important for you to report these weather data in this much detail. Perhaps, a table of avg/min/max rain and temp for each of the crop cycles would be sufficient values.
Troubleshooting: What is class(data_for_graphs$Day)
? I have not seen different y-axis plotted together in R. The best practice would be to have separate plots for rain and temp. Remember the steps for troubleshooting that strip as much complexity from the code in a manner that allows you to investigate the functionality of each of the individual pieces. It also looks to me like scale_x_discrete()
is a bit misused here. ggplot2
docs suggest labs()
for what you're asking. Also, notice that the name
for the y-axis is not "Temperature (C)"
and their is no title, another indication of the location where there is something not properly functioning.
I'm trying to map the temp and precip together for each season, but I keep getting the error Error in UseMethod("rescale") : no applicable method for 'rescale' applied to an object of class "character" but they are all numbers. The only character is Day, and when I reassign it as a number, it gives me this error "Error: Cannot add ggproto objects together. Did you forget to add this object to a ggplot object?"
