Print Coefficient Matrices

Description

Utility function to be used in higher-level print methods, such as print.summary.lm, print.summary.glm and print.anova. The goal is to provide a flexible interface with smart defaults such that often, only x needs to be specified.

Usage

printCoefmat(x, digits=max(3, getOption("digits") - 2),
             signif.stars = getOption("show.signif.stars"),
             signif.legend = signif.stars,
             dig.tst = max(1, min(5, digits - 1)),
             cs.ind = 1L:k, tst.ind = k + 1L,
             zap.ind = integer(0), P.values = NULL,
             has.Pvalue = nc >= 4L &&
                          substr(colnames(x)[nc], 1L, 3L) == "Pr(",
             eps.Pvalue = .Machine$double.eps,
             na.print = "NA", ...)

Arguments

`x`	a numeric matrix like object, to be printed.
`digits`	minimum number of significant digits to be used for most numbers.
`signif.stars`	logical; if `TRUE`, P-values are additionally encoded visually as ‘significance stars’ in order to help scanning of long coefficient tables. It defaults to the `show.signif.stars` slot of `options`.
`signif.legend`	logical; if `TRUE`, a legend for the ‘significance stars’ is printed provided `signif.stars=TRUE`.
`dig.tst`	minimum number of significant digits for the test statistics, see `tst.ind`.
`cs.ind`	indices (integer) of column numbers which are (like) coefficients and standard errors to be formatted together.
`tst.ind`	indices (integer) of column numbers for test statistics.
`zap.ind`	indices (integer) of column numbers which should be formatted by `zapsmall`, i.e., by ‘zapping’ values close to 0.
`P.values`	logical or `NULL`; if `TRUE`, the last column of `x` is formatted by `format.pval` as P values. If `P.values = NULL`, the default, it is set to `TRUE` only if `options("show.coef.Pvalue")` is `TRUE` and `x` has at least 4 columns and the last column name of `x` starts with `"Pr("`.
`has.Pvalue`	logical; if `TRUE`, the last column of `x` contains P values; in that case, it is printed if and only if `P.values` (above) is true.
`eps.Pvalue`	number,..
`na.print`	a character string to code `NA` values in printed output.
`...`	further arguments for `print`.

Value

Invisibly returns its argument, x.

Examples

cmat <- cbind(rnorm(3, 10), sqrt(rchisq(3, 12)))
cmat <- cbind(cmat, cmat[,1]/cmat[,2])
cmat <- cbind(cmat, 2*pnorm(-cmat[,3]))
colnames(cmat) <- c("Estimate", "Std.Err", "Z value", "Pr(>z)")
printCoefmat(cmat[,1:3])
printCoefmat(cmat)
options(show.coef.Pvalues = FALSE)
printCoefmat(cmat, digits=2)
printCoefmat(cmat, digits=2, P.values = TRUE)
options(show.coef.Pvalues = TRUE)# revert
