Using `geom_line()` with X axis being factors

Question

Suppose I have a dataframe:

hist <- data.frame(date=Sys.Date() + 0:13,
                   counts=1:14)

I want to plot the total count ag

Answer 1

If I understand the issue correctly, specifying group=1 and adding a stat_summary() layer should do the trick:

ggplot(hist, aes(x=weekday, y=counts, group=1)) +
geom_point(stat='summary', fun.y=sum) +
stat_summary(fun.y=sum, geom="line")
