n2c: Show absolute values as characters, prepare for plotting

Description

n2c takes a numerical vector or matrix and represents it as single characters, with legend. indexLine generates a string with dots, ";", and digits, usable as x-label in n2cCompact: .....;....1....;....2.. n2cCompact combines n2c and indexLine to generate a vector of strings good for printing numerical matrices. charMat processes the output from n2cCompact and returns vectors x, y, tx of equal lengths for input to pltCharMat

Usage

n2c(x, symm = FALSE)
  indexLine(n)
  n2cCompact(x, symm=FALSE)
  charMat(cc)

Arguments

x

A numerical vector or matrix.

symm

If symm = TRUE then upper triangle will be suppressed.

n

integer, length of string wanted

cc

output from n2cCompact, input to charMat

Value

• n2c: Representation of x as a single-character vector or matrix, as explained in attribute legend. charMat: list(x,y,txt)
