Hi,
I am having problem with ggplot2. When I type
ggplot(Data,
aes(x = Season, y = Aeromonas)) +
geom_boxplot(fill='lightblue', color='blue') +
geom_point(color='darkblue')
a perfect graph showed up.
But when I type
ggplot(Data,
aes(x = Water type, y = Aeromonas)) +
geom_boxplot(fill='lightblue', color='blue') +
geom_point(color='darkblue')
This error message popped up
Error: Cannot add ggproto objects together. Did you forget to add this object to a ggplot object?
Please help me. What's the problem?
