as_bm_list: Coerce to bitmap list objects

Description

as_bm_list() turns an existing object into a bm_list() object. In particular as_bm_list.character() turns a string into a bitmap list.

Usage

as_bm_list(x, ...)
# S3 method for default
as_bm_list(x, ...)
# S3 method for bm_list
as_bm_list(x, ...)
# S3 method for list
as_bm_list(x, ..., FUN = identity)
# S3 method for character
as_bm_list(x, ..., font = bm_font())

Value

  bml <- as_bm_list("RSTATS", font = font)
  bml <- bm_extend(bml, sides = 1L, value = 0L)
  bml <- bm_extend(bml, sides = c(2L, 1L), value = 2L)
  bm <- do.call(cbind, bml)
  print(bm, px = c(" ", "#", "X"))
