Hi ,
  
    I am using nls(formula)
  
  where formula is y~ expression
  
  y  is 1 character
  ~  is 1 character
  
  now i have an expression that is greater tha 502 characters. but R does  not recognize anything greater than 502 characters. (Note the  expression itself is created using paste and as.formula commands)
  
  Does anyone have a suggestion. (BTW i have checked my formula and its right in case you have doubts about its length)
  
  Thanks.
