lm_adjusted_r_squared: Calculate adjusted r-squared using lm object

In jeromyanglim/personalityfacets: Package for estimating population r-square change

Description

This function is an alternative way of calling adjusted_r_squared. It derives n, p, and rsquared from an lm object.

Usage

lm_adjusted_r_squared(fit, method = c("ezekiel", "smith", "olkinpratt",
  "pratt", "wherry1", "wherry2"))

Arguments

fit	object of class lm
method	method used calculating r-squared (see adjusted_r_squared)

Value

adjusted r-squared

Examples

# Get data and meta data
data(facets_data); data(facets_meta)
facets_meta$ipip_factors

# Example showing the use of the regression function
fit1 <- regression('swl', ivs= facets_meta$ipip_factors, data=facets_data)
lm_adjusted_r_squared(fit1, method='olkinpratt')

# Example showing use of lm formula and how ezekiel values are equivalent
fit2 <- lm(swl ~ ipip_extraversion + ipip_openness, facets_data)
lm_adjusted_r_squared(fit2, method='ezekiel')
summary(fit2)$adj.r.squared
