rSquared {FSA} | R Documentation |
Extracts the coefficient of determination (i.e., “r-squared”) from a linear model (i.e., lm
) object.
rSquared(object, ...) ## Default S3 method: rSquared(object, ...) ## S3 method for class 'lm' rSquared(object, digits = getOption("digits"), percent = FALSE, ...)

Additional arguments for methods. |
digits |
A single number that is the number of digits to round the returned result to. |

A logical that indicates if the result should be returned as a percentage ( |
This is a convenience function to extract the r.squared
part from summary(lm)
.
A numeric, as either a proportion or percentage, that is the coefficient of determination for a linear model.
lm1 <- lm(mirex~weight, data=Mirex) rSquared(lm1) rSquared(lm1,digits=3) rSquared(lm1,digits=1,percent=TRUE) ## rSquared only works with lm objects ## Not run: nls1 <- nls(mirex~a*weight^b,data=Mirex,start=list(a=1,b=1)) rSquared(nls1) ## End(Not run)
