ggplot2 and facet_wrap help
...price'
# So my data is already in a "long" format I think, but when I do this:
ggplot(data=mydf, aes(x=mydf$size2, y=mydf$median_price,
group=as.factor(mydf$clarity), colour=as.factor(mydf$clarity))) +
geom_line() + facet_wrap(~ factor(mydf$size1))
I get this error:
"Error in layout_base(data, vars, drop = drop) :
At least one layer must contain all variables used for facetting"
Can you please help me understand what I am doing wrong?
