print.summary_greek: Print Summary for Linear Model Fits With Greek Letters

Description

print summary method with Greek letters for class "lm".

Usage

# S3 method for summary_greek
print(
  x,
  digits = max(3L, getOption("digits") - 3L),
  symbolic.cor = x$symbolic.cor,
  signif.stars = getOption("show.signif.stars"),
  concise = FALSE,
  ...
)

Value

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

Arguments

x

an object used to select a method.

digits

minimal number of significant digits, see print.default.

symbolic.cor

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

signif.stars

logical. If TRUE, ‘significance stars’ are printed for each coefficient.

concise

logical.

...

Arguments passed on to base::print, stats::summary.lm

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.

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.
