I have the following data set:

```
depth <- data.frame(Sample = c("AD_001", "AD_009", "AD_017", "AD_025",
"AD_033", "AD_041", "AD_049", "AD_057",
"AD_065", "AD_073", "AD_081", "AD_089"),
median = c(12, 13, 11, 12, 12, 12, 13, 13, 14, 15, 15, 13),
granular_first_quartile = c(5, 6, 5, 6, 5, 6, 6, 6, 7, 7, 7, 6),
granular_third_quartile = c(23, 25, 21, 22, 23, 23, 24, 25, 27, 28, 28, 24))
```

and would like to create a boxplot but, the graphs I'm generating do not have an equally separated x field.

```
ggplot(depth, aes(as.factor(Sample))) + geom_boxplot(aes(middle = median, lower = granular_first_quartile, upper = granular_third_quartile, ymin = granular_first_quartile, ymax = granular_third_quartile), stat = 'identity') + coord_flip()
```

Thanks for the help!
