In claus-e-andersen/clanTools: R functions of general use for data analysis and presentation

Print number to fit certain format. An alternative is used if this requires too many characters.

Description

This is a variation of sprintf, that checks if the formated result is too long. This can happen, for example, with electrometer output, where normal results are 0.004 pC and then an overflow gives a charge of 6e47 C, which produces an output that ruins txtplot table output.

Usage

sprintf.ca("%.5f", c(1.23, 2.33, 1e99), max.chars=7)

Arguments

format	is the main format (e.g. "%.5f") which is used if the output does not require too many characters.
number	to print (e.g. 1.334 or 1.4e99).
format.alt	is the alternative format (e.g. "%.4e") which is used for output that require too many characters.
max.char	is the maximum number of characters (e.g. 10) that the main format needs to fit (otherwise the alternative format will be used).

Value

formated number.
