How to develop a boxplot using the inbuilt dataset "trees" in ggplot2.
I tried creating a boxplot keeping aes ( x and y) but it creates a boxplot againts "Girth" and "Volume", while I need a boxplot which the R base creates for the same data only using "
boxplot(trees)
ggplot2 works different from base R plotting, i.e. to create a boxplot of several columns you first have to reshape your data to long format using e.g. tidyr::pivot_longer:
library(ggplot2)
library(tidyr)
trees_long <- trees |>
pivot_longer(everything(), names_to = "name", values_to = "value")
trees_long
#> # A tibble: 93 × 2
#> name value
#> <chr> <dbl>
#> 1 Girth 8.3
#> 2 Height 70
#> 3 Volume 10.3
#> 4 Girth 8.6
#> 5 Height 65
#> 6 Volume 10.3
#> 7 Girth 8.8
#> 8 Height 63
#> 9 Volume 10.2
#> 10 Girth 10.5
#> # … with 83 more rows
ggplot(trees_long, aes(name, value)) +
geom_boxplot()
