Description

summary method with Greek letters for class "lm".

Usage

1
summary_greek(object, correlation = FALSE, symbolic.cor = FALSE, ...)

Arguments

object

an object of class "lm", usually, a result of a call to lm.

correlation

logical; if TRUE, the correlation matrix of the estimated parameters is returned and printed.

symbolic.cor

logical. If TRUE, print the correlations in a symbolic form (see symnum) rather than as numbers.

...

Arguments passed on to stats::summary.lm

Details

It is recommended that the font size of the R console be increased for better visualization of the symbols, as some of the symbols are quite small.

Value

The function is like summary.lm but with Greek letters in output.
