Split a string of values and return as boolean vector

The purpose of this function is combine the functionality of strsplit, unlist and as.logical, which are often used together.

Usage

strsplit.bool(
  x,
  split,
  fixed = FALSE,
  perl = FALSE,
  useBytes = FALSE,
  type = 2
)

Arguments

x: character vector, each element of which is to be split. Other inputs, including a factor, will give an error.
split: character vector
fixed: logical. If TRUE match split exactly, otherwise use regular expressions. Has priority over perl.
perl: logical. Should Perl-compatible regexps be used?
useBytes: logical. If TRUE the matching is done byte-by-byte rather than character-by-character, and inputs with marked encodings are not converted.
type: type of return, see the as.boolean function for more info

Value

boolean values based on split string

Details

Given a sting, split by a separator into boolean

Examples

# string of numbers
num.01 = "0 1 0 0 1 0 1 T F TRUE FALSE t f"

# split a string of numbers and return as boolean 1/0
strsplit.bool(num.01, split = " ", type = 3)
#>  [1] 0 1 0 0 1 0 1 1 0 1 0 1 0
#> Levels: 0 1

# split a string of numbers and return as boolean TRUE/FALSE
strsplit.bool(num.01, split = " ", type = 2)
#>  [1] FALSE  TRUE FALSE FALSE  TRUE FALSE  TRUE  TRUE FALSE  TRUE FALSE  TRUE
#> [13] FALSE

# split a string of numbers and return as boolean Yes/No
strsplit.bool(num.01, split = " ", type = 1)
#>  [1] No  Yes No  No  Yes No  Yes Yes No  Yes No  Yes No 
#> Levels: No Yes


# string of numbers
num.02 = "0abc1abc0abc0abc1abc0abc1abcTabcFabcTRUEabcFALSEabcf"

# split a string of numbers and return as boolean 1/0
strsplit.bool(num.02, split = "abc", type = 3)
#>  [1] 0 1 0 0 1 0 1 1 0 1 0 0
#> Levels: 0 1

# split a string of numbers and return as boolean TRUE/FALSE
strsplit.bool(num.02, split = "abc", type = 2)
#>  [1] FALSE  TRUE FALSE FALSE  TRUE FALSE  TRUE  TRUE FALSE  TRUE FALSE FALSE

# split a string of numbers and return as boolean Yes/No
strsplit.bool(num.02, split = "abc", type = 1)
#>  [1] No  Yes No  No  Yes No  Yes Yes No  Yes No  No
