hello, I am trying to make a line chart of a model with two binary X and a continous Y. When I specify one of X as the x axis and in continuous scale, the plot is mostly fine, only that the x axis has other values between 0 and 1 (because I specified it as continuous). The code looks like below:
Since the x axis contains other values between 0 and 1, I specify X as a binary variable, but the code didnt work:
ggplot(mtcars,aes(y=mpg,x=as.factor(vs),color=as.factor(gear)))+stat_summary(fun='mean',geom='line') geom_path: Each group consists of only one observation. Do you need to adjust the group aesthetic?
Why is that? Please give me some advice. Thank you very much.
