[R] Bimodal deconvolution

[Seth Imhoff]

Hi Everyone-

After searching through posts and my favorite R-help websites I'm still confused about a problem.  I have data which is bimodal in nature, but there is no clearly obvious separation between the two peaks.  In programs such as Origin, I can deconvolute the two distributions and have it generate a "best guess" as to what the two subpopulations are which make up my dataset.  Below is a link to a figure which represents what I would like to accomplish here (it is the best I can do so far).
