Q
    {r}
    cambio2 <- data.frame(cambio)
    cambio2 %>%
      ggplot(aes(y = receita,
                 x = despesa
                          )
    ) + geom_point()
I want to make the chart, but there are no dots in the chart and the following error appears:
Error in a - b : non-numeric argument to Binary Operator
Thanks in advance


Present a sample of your data so we can understand what kind of problem is occurring. Use dput(cambio2) to get the sample and edit the post with that output.
