Package 'geocacheR'

Create "hashes" of the letters in a character vector

Description

The "hash" here is not a true hash, since the output has a variable number of characters, but is instead a string representation of the number of characters in the input string in hexadecimal format.

Usage

alphash(x, case_sensitive = FALSE, alphabet = standard_alphabet)

Arguments

x	A character vector to be hashed
case_sensitive	NOT IN USE. This parameter will probably be removed
alphabet	NOT IN USE. This parameter will probably be removed

Value

A character vector equal in length to the input x

Make a frequency table of the characters in a string

Description

Make a frequency table of the characters in a string

Usage

analyse_frequency(
  x,
  case_sensitive = FALSE,
  alphabet = standard_alphabet,
  collapse = FALSE
)

Arguments

x	A character vector
case_sensitive	Logical. Should lower and upper case letters be kept separate
alphabet	A list containing lower and upper case alphabets
collapse	A character value to be passed to paste() to collapse x into a single string. If collapse=FALSE (default), no collapse is implemented

Value

A tibble of the frequencies, with one row for each input string

What 3 Words wrapper

Description

This function requires you to have a valid what3words API key called W3WAPIKey stored as an environment variable

Usage

w3w(x)

Arguments

x

A vector, or list, of words. Strings with dots in them will be split. After splitting, there must be a multiple of three words. Either a vector of words, for a single latitude/longitude pair, or a list of vectors for vectorised operations. This wrapper also accepts a single string of three words separated by full stops.

Value

a numeric vector of length 2, consisting of lat(itude) and lon(gitude)

Examples

## Not run: 
w3w("president.always.lying")
w3w("unseen.academicals.football") ## returns NAs
w3w(list("special.tools.required", "cliffs.falling.rocks",
         "available.during.winter", "ultraviolet.light.required"))
w3w(c("protests", "memo", "consoles"))

## End(Not run)
