[R] bimodal data

[Charles Annis, P.E.]

Your problem sounds like it could be modeled with logistic regression
whereby the propensity for one result or another is "linked" to the factors
that control it.  Logistic regressions are a special case of generalized
linear models.  Look at ?glm

    Hi,
   
  Does anybody have a good tip of how to treat bimodal data to perform
statistical analyses? My data set ranges from -1 to 1 (any values are
posssible in between) and most data are either close to -1 or close to 1.
They are the results of a two choice experiment where individuals could
choose more than once in either direction and scores were calculated.
   
  Simone
