[R] ggmap, hexbin and length distortion in Lat/long

I am working with spatial data in ggmap, generally with great success. I have a huge data set with the coordinates in NAD 83 UTM Zone 11 (meters). To map the data the coordinates were converted to Lat Long in GIS prior to use in R and ggmap/ggplot. I am using hexagonal binning to aggregate the

[R] Fitting Multiple Univariate Distributions to Data

I am looking for procedure that allow one to fit multiple distributions to a variable. For example, based on analysis of the data we suppose that the data can be represented by 3-5 normal distributions added together. I would like to be able to determine the mean, sd, and weight associated
