This is one of the most frequent questions on this list. There are many answers, of which my favourite is to use -poisson- or -glm, link(log)- i.e. use a link function that indulges zeros in the data, not a transformation. However, if the zeros arise from some quite distinct process, you may need something more complicated.

Thank you, Cam. I will read the articles mentioned below. What would you suggest for dealing with zero values when log transforming data?
