How to fix x-axis names?

Question

I have the following dataset:

a<-data.frame(time=c("before","after","before","after"),
                  company=c(1,1,2,2),
                  value=c(3.751522,4.776224,3.838707,2.644144 ))

And to plot a graph I used the following code

a$company<-as.factor(a$company)
ggplot(a, aes(x=company, y=value, fill=time)) + geom_col(position="dodge")

As a result, I have the figure for two companies with after and before bars. However, how to fix a problem that the first bar of the company corresponds to the before and next to the after, and not vica versa as in my graph?

Does this achieve what you want:

a<-data.frame(time=factor(c("before","after","before","after"),
                          levels = c("before", "after")),
              company=c(1,1,2,2),
              value=c(3.751522,4.776224,3.838707,2.644144 ))
a$company<-as.factor(a$company)
ggplot(a, aes(x=company, y=value, fill=time)) + geom_col(position="dodge")

Agree with this. I might even use `ordered()` instead of `factor()` on the time column. – Adam Sampson Aug 01 '19 at 21:08
Thanks, it is working – John Mayer Aug 02 '19 at 13:10
