In mengqi00/linear1: linear regression (Title Case)

linear1

Overview

linear1 is intended to mimic the original R function lm, which stands for linear regression.

It currently has two functions:

• lm1 reads the formula of a linear model and return an invisible list of values of the linear model.
• summary1 reads the return value of lm1 and mimics the output of the original summary function based on lm.
• diagnosis reads the return value of lm1 and returns different types residuals of the model. At the same time it prints a plot consisting of residual plot, qqplot, scale-location plot and standardized residuals vs leverage plot, which in some extend mimics the original function plot based on lm.

Install

devtools::install_github("mengqi00/linear1")

Use

library(linear1)

### fit a linear model
model <- lm1(mpg ~ disp + wt, data = mtcars)

### get summaries of the model's results
summary1(model)

### get residuals and plot
diagnosis(model)

Get help

There are help pages for each function, use help(lm1), help(summary1), and help(diagnosis) to see more examples.
