In jedwards24/edwards: James Edwards personal package

dplyr::count() with proportion column and default sort = TRUE

Description

Adds a column which gives the proportion of total rows in that group.

• vcount() is similar but works with a vector input.

• countp() and countv() are alternative names for, respectively, count2() and vcount().

Usage

count2(df, ..., sort = TRUE, wt = NULL, name = NULL, pname = NULL)

countp(df, ..., sort = TRUE, wt = NULL, name = NULL, pname = NULL)

vcount(x, sort = TRUE, name = NULL, pname = NULL)

countv(x, sort = TRUE, name = NULL, pname = NULL)

Arguments

df	A data frame.
...	Variables to group by. Passed to count().
sort	Passed to count, but defaults to TRUE.
wt, name	Optional, passed to count.
pname	Name for the proportion column. If omitted, it will default to p. If there's already a column called p, it will use pp. If there's a column called p and pp, it'll use ppp, and so on, adding ps until it gets a new name.
x	A vector (including a data frame).
