Count the occurrences of unique values

Description

Usage

<Series>$value_counts(
  ...,
  sort = TRUE,
  parallel = FALSE,
  name = "count",
  normalize = FALSE
)

Arguments

`…`	Ignored.
`sort`	Ensure the output is sorted from most values to least.
`parallel`	Better to turn this off in the aggregation context, as it can lead to contention.
`name`	Give the resulting count column a specific name. The default is `“count”` if `normalize = FALSE` and `“proportion”` if `normalize = TRUE`.
`normalize`	If `TRUE`, it gives relative frequencies of the unique values instead of their count.

Value

DataFrame
