R- making a figure from multiple vectors of different lengths

Question

I have 8 vectors all with different lengths (ranging from 5 to 110) I would like to display box plots for each vector on the same figure but am running into all sorts of issues- are there any packages that make this easier? If anyone can lead me in the right direction that would be greatly appreciated! Bonus points if there's an answer using ggplot2!

Answer 1

Sample data:

set.seed(42)
### these are your data vectors
vec1 <- rnorm(20) ; vec2 <- rexp(30, 3) ; vec3 <- rnorm(40, 3, 5)

Combine them into one "long" frame:

### create a "long" frame
dat <- dplyr::bind_rows(A = data.frame(val = vec1), B = data.frame(val = vec2), C = data.frame(val = vec3), .id = "id")
head(dat)
#   id        val
# 1  A  1.3709584
# 2  A -0.5646982
# 3  A  0.3631284
# 4  A  0.6328626
# 5  A  0.4042683
# 6  A -0.1061245

The plot:

library(ggplot2)
ggplot(dat, aes(id, val)) + geom_boxplot()
