Order and sort vectors

vec_order(x, direction = c("asc", "desc"), na_value = c("largest", "smallest"))

vec_sort(x, direction = c("asc", "desc"), na_value = c("largest", "smallest"))

Arguments

x

A vector
direction

Direction to sort in. Defaults to ascending.
na_value

Should NAs be treated as the largest or smallest values?

Value

  • vec_order() an integer vector the same size as x.

  • vec_sort() a vector with the same size and type as x.

Examples

x <- round(c(runif(9), NA), 3)
vec_order(x)
#>  [1]  4  3  9  6  7  5  8  1  2 10
vec_sort(x)
#>  [1] 0.359 0.500 0.567 0.584 0.634 0.775 0.859 0.888 0.996    NA
vec_sort(x, "desc")
#>  [1]    NA 0.996 0.888 0.859 0.775 0.634 0.584 0.567 0.500 0.359

# Can also handle data frames
df <- data.frame(g = sample(2, 10, replace = TRUE), x = x)
vec_order(df)
#>  [1]  4  3  6  7  1  2  9  5  8 10
vec_sort(df)
#>    g     x
