parseNumVec: Parse a character string into a numveric vector

In bedapub/ribiosArg: Argument handling for command-line, stand-alone R scripts

Description

Numeric vectors can be given as arguments in two ways: (1) separated by blanks or (2) separated by other common separators, such as comma (,). This function parses a string, or a string vector into a numeric vector of expected length. In addition it is failure safe: user can specify the return value in case the parsing was not successful,

Usage

parseNumVec(str, expLen = 2, failVal = c(5, 5), sep = ",")

Arguments

str	A character string
expLen	Integer or NULL, Expected length of the numeric vector. When set to NULL, the numeric vector can be of variable length.
failVal	If the parsing failed (for example length not correct, or non-numeric values were provided, this value will be returned
sep	Separator in the character string, default ","

Details

The input value mostly comes from return values of the argGet function.
