Is there a way to set the x-axis to min and max value in ggplot?

Data:

Month<-c(jan,feb,mar,apr,may)
Values(10,5,8,12,4)

I was wondering if there is a way to set the x axis to min and max values without hardcoding it. For example instead of hard coding coord_cartesian(ylim = c(4, 12)) is there a way to just assign y axis to max and min so the graph automatically sets the limits at 4 and 12.

We can extract the range from the 'Values' column

library(ggplot2)
ggplot(df1, aes(x = Month, y = Values)) + 
     geom_col() + 
     coord_cartesian(ylim = range(df1$Values))

-output

enter image description here

If we need to change the tick marks, use scale_y_continuous

rng_values <- range(df1$Values) -  c(2, 0)
ggplot(df1, aes(x = Month, y = Values)) + 
     geom_col() + 
     coord_cartesian(ylim = rng_values ) + 
     scale_y_continuous(breaks = do.call(seq, 
        c(as.list(rng_values),
            list(by = 0.5))))

data

df1 <- data.frame(Month = month.abb[1:5], Values = c(10, 5, 8, 12, 4))
