strsplit.bool: Split a string of values and return as boolean vector

In quickcode: Quick and Essential 'R' Tricks for Better Scripts

Split a string of values and return as boolean vector

Description

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

Details

Given a sting, split by a separator into boolean

Value

boolean values based on split string

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)

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

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


# 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)

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

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