vector1 <- c(1, 4, 5, 6, 2, 4, 5, 8)
vector2 <- c("level1", "level2", "level2", "level1", "level3", "level2", "level2", "level3")
dataframe <- data.frame(vector1, vector2)
dataframe$vector2 <- as.factor(dataframe$vector2)


plot <- ggplot(dataframe, aes(vector2, vector1))
plot +geom_bar(stat = "identity")

Say you have a class imbalance in factor 1 and you want to focus on a bar plot that isolates just factor one as a singular bar chart. How can I make it be the only level to show up on the x-axis?

You could just call `ggplot(dataframe %>% filter(factor = "level1"))` – Calum You Mar 22 '18 at 18:27
This doesn't seem to work. I get "ErrorL filter() takes unnamed arguments. Do you need '=='? – hmnoidk Mar 22 '18 at 20:00
Yeah that's my typo, use `factor == "level1"` – Calum You Mar 22 '18 at 20:30
and when you want to increase the number of levels without typing each level manually? – Ben Dec 03 '19 at 07:24
