We all know that we can compute any summary that operates on vectors and returns a single value in R base. I want to ask that why I don't get an error when I attempt to use quantile which returns more than one value function inside of summarize?
heights %>%
filter(sex == "Male") %>%
summarize(range = quantile(height, c(0, 0.5, 1)))
result is not an error:
range
1 50.00000
2 69.00000
3 82.67717
Just making my comment and @27ϕ9's an answer.
As of dplyr version 1.0.0, summarise allows to return outputs containing more than one value.
Example:
mtcars %>%
group_by(cyl) %>%
summarise(qs = quantile(disp, c(0.25, 0.75)), prob = c(0.25, 0.75))
# A tibble: 6 x 3
# Groups: cyl [3]
# cyl qs prob
# <dbl> <dbl> <dbl>
# 1 4 78.8 0.25
# 2 4 121. 0.75
# 3 6 160 0.25
# 4 6 196. 0.75
# 5 8 302. 0.25
# 6 8 390 0.75
See the documentation for more examples.
