Round a matrix to N signifcant digits in mixed FP/exp notation

Description

Round a matrix to N signifcant digits in mixed FP/exp notation

Usage

formatMat(x, digits = 3, shave.spaces = TRUE)

Arguments

x	Numeric matrix.
digits	Positive integer: the number of digits after the decimal comma to round to (i.e. one less than the number of significant digits).
shave.spaces	Logical: if true, removes spaces to ensure compact output; if false, results in nearly fixed-width output (almost).

Value

A numeric matrix with all entries of equal width with the same number of characters

Examples

x <- matrix(c(1234567, 12345.67, 123.4567,
              1.23456, -1.23456e-1, 0,
              -1.23456e-4, 1.23456e-2, -1.23456e-6), nrow = 3)
print(formatMat(x), quote = FALSE)
print(formatMat(x, digits = 1), quote = FALSE)
