I have a variable ceroonce which is number of schools per county (integers) in 2011. When I plot it with `boxplot()` it only requires the ceroonce variable. A boxplot is then retrieved in which the y axis is the number of schools and the x axis is... the "factor" ceroonce. But in `ggplot`, when using `geom_boxplot`, it requires me to input both x and y axis, but I just want a boxplot of ceroonce. I have tried inputing ceroonce as both the x and y axis. But then a weird boxplot is retrieved in which the y axis is the number of schools but the x axis (which should be the factor variable) is also the number of schools? I am assuming this is very basic statistics, but I am just confused. I am attaching the images hoping this will clarify my question. 

This is the code I am using:

```
ggplot(escuelas, aes(x=ceroonce, y=ceroonce))+geom_boxplot()
boxplot(escuelas$ceroonce)

```
