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

Source: R/bc.R

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

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

Value

vector of values

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.

Examples


bc('1 2 "c", d') # returns c("1", "2", "c", "d")

#> [1] "1" "2" "c" "d"
bc('1 2 3') # returns c(1, 2, 3)

#> [1] 1 2 3
bc('1 2 "3"') # returns c("1", "2", "3")

#> [1] "1" "2" "3"
bc('1,2|3.4') # returns c(1, 2, 3.4)

#> [1] 1.0 2.0 3.4
bc('01 02', convert=FALSE) # returns c("01", "02")

#> [1] "01" "02"
