Print Coefficient Matrices

Description

Utility function to be used in higher-level print methods, such as those for summary.lm, summary.glm and 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(), 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)
op <- options(show.coef.Pvalues = FALSE)
printCoefmat(cmat, digits = 2)
printCoefmat(cmat, digits = 2, P.values = TRUE)
options(op) # restore
