Perform correlation and linear regression for a data.frame automatically

Description

Perform correlation and linear regression for a data.frame automatically

Usage

mycor(x, ..., digits)

## Default S3 method:
mycor(x, ..., digits = 3)

## S3 method for class 'formula'
mycor(formula, data, ..., digits = 3)

Arguments

x

A data.frame.

...

further arguments to be passed to cor.test.

digits

integer indicating the number of decimal places (round) or significant digits (signif) to be used.

formula

a formula of the form ~ u + v, where each of u and v are numeric variables giving the data values for one sample. The samples must be of the same length.

data

A data.frame

mycor

Object to mycor

Value

mycor returns as object of class "mycor"

The function summary is used to print a summary of the result. The function plot is used to plot the results using pairs and parallelplot.

An object of class "mycor:" is a list containing at least following components:

df

a data.frame

select

logical vectors returns if columns of df is.numeric

out

a list of class "htest" from cor.test between the last paired samples in a data.frame.

r

a matrix consist of r values from cor.test between all pairs of numeric data from a data.frame

p

a matrix consist of p values from cor.test between all pairs of numeric data from a data.frame

slope

a matrix consist of slope values from lm between all pairs of numeric data from a data.frame

intercept

a matrix consist of intercept values from lm between all pairs of numeric data from a data.frame

Methods (by class)

Examples

out=mycor(iris)
plot(out)
plot(out, groups=Species)
plot(out,type=2,groups=species)
plot(out,type=4,groups=species)
out1=mycor(~mpg+disp+wt+hp,data=mtcars,alternative="greater",methods="kendall",
            conf.level=0.95)
plot(out1,type=3)
plot(out1,type=4,groups=cyl)

Correlation and Fitting linear model function for function "mycor"

Description

Correlation and Fitting linear model function for function "mycor"

Usage

mylm(y, x, ..., digits = 3)

Arguments

y

numeric vectors of data values

x

numeric vectors of data values

...

further arguments to be passed to or from methods.

digits

integer indicating the number of decimal places (round) or significant digits (signif) to be used.

Value

mylm returns a list of following components

out

a list of class "htest" from cor.test between the last paired samples in a data.frame.

result

a numeric vector of length 4, consist of r and p values from cor.test,slope and intercept values from lm between numeric vector y and x

Make correlation plot for plot of class "mycor"

Description

Make correlation plot for plot of class "mycor"

Usage

panel.cor(x, y, digits = 2, prefix = "", cex.cor)

Arguments

x

a numeric vector

y

a numeric vector

digits

integer indicating the number of decimal places (round) or significant digits (signif) to be used.

prefix

a character vector

cex.cor

a numeric variable

Make plot with histogram for plot of class "mycor"

Description

Make plot with histogram for plot of class "mycor"

Usage

panel.hist(x, ...)

Arguments

x

a numeric vector

...

further arguments to be passed to or from methods.

Plot for an object of class "mycor"

Description

Plot for an object of class "mycor"

Usage

## S3 method for class 'mycor'
plot(x, ..., groups = -1, type = 1)

Arguments

x

an object of class "mycor"

...

further arguments to be passed to pairs or parallelplot(in case of "type" argument is 4).

groups

a variable to be evaluated in a data.frame x$df, expected to act as a grouping variable within each panel, typically used to distinguish different groups by varying graphical parameters like color and line type.

type

specify the type of plot

Examples

 out=mycor(iris)
 plot(out)
 plot(out, groups=Species)
 plot(out,type=2,groups=species)
 out1=mycor(mtcars[1:5],alternative="greater",methods="kendall",
