Your example is incomplete... as the bottom of this and every post says, we need to be able to proceed from an empty R environment to wherever you are having the problem (reproducible), in as few steps as possible (minimal). The example needs to include data, preferably in R syntax as the dput function creates... see the howtos referenced below for help with that.  [1], [2], [3]

You also need to set your email program to send plain text format, since HTML gets mangled to various degrees as it gets forced into text format going through the mailing list. Read the Posting Guide. 

A wild guess is that you have negative values in your data or too few data points...
