# summary_greek: Summarizing Linear Model Fits With Greek Letters In greekLetters: Routines for Writing Greek Letters and Mathematical Symbols on the 'RStudio' and 'RGui'

## 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.
