bc: Blank Concatenate. Parse argument as a vector of values...

In wrapr: Wrap R Tools for Debugging and Parametric Programming

Blank Concatenate. Parse argument as a vector of values allowing "blank separators".

Description

Separates string data on whitespace and separating symbols into an array.

Usage

bc(s, ..., sep_symbols = ",|", strict = TRUE, convert = TRUE)

Arguments

s	string to parse
...	force later arguments to be set by name
sep_symbols	characters to consider separators
strict	logical, if TRUE throw exception on confusing input
convert	logical, if TRUE try to convert from string type to other types

Details

Can throw exception on lack of explicit value separators, example: bc('"a""b"') and non-matching portions. Whitespace is normalized to spaces. Attempts to split on obvious number format boundaries. Suggested by Emil Erik Pula Bellamy Begtrup-Bright https://github.com/WinVector/wrapr/issues/12.

Value

vector of values

Examples

bc('1 2 "c", d') # returns c("1", "2", "c", "d")
bc('1 2 3') # returns c(1, 2, 3)
bc('1 2 "3"') # returns c("1", "2", "3")
bc('1,2|3.4') # returns c(1, 2, 3.4)
bc('01 02', convert=FALSE) # returns c("01", "02")
