# Functions for manipulating/transforming character strings: ------ 


# vec2str: Turn a vector of symbols into a character string: ------

# (See collapse_chars() AND chars_to_text() in ds4psy package.)

vec2str <- function(v) {
  
  paste(v, collapse = "")
  
  # Note: Simply using paste(v, collapse = "") loses all spaces.
  #       ds4psy::chars_to_text() preserves spaces. 
  
} # vec2str(). 



# str2vec: Turn a character string into a vector (of 1-symbol character elements): ------ 

# (See text_to_chars() in ds4psy package.)

str2vec <- function(s){
  
  unlist(strsplit(s, split = ""))  # assumes ONLY 1-symbol elements/digits
  
} # str2vec().
