Descriptives: Descriptives

Description

This function calculate to return answer which are descriptive statistics values for a continuously variable or continuously variables in data frame.

Usage

Descriptives(x, plot = FALSE, r = 2, answer = 1, statistic = "ALL")

Arguments

x

A continuously variable or a data frame contain continuously variables.

plot

Parameter 'Plot' are used by 2 form: Let plot=TRUE to paint description graph when x is time series. Let plot=list(a1,a2,...) (in a1,a2,...are descriptive statistic values as 'Mean', 'Max',...) to paint comparing graph between variables.

r

Rounds the answer to the specified number of decimal places (default 2).

answer

Form of answers are returned. Let answer=1 or answer=2 (default 1)

statistic

A list contain descriptive statistic values that user want R print screen (default ALL).
