I am a PhD in Statistics with relevant experience in the use of R and in multivariate and cluster analysis - I have publications on international reviews on the topic. I have also teaching experience, which has provided me with skills in presenting technical aspects and results to non-technical people.
Which kind of problems are you experiencing? What do you mean when you say "error"? What aspects do you need to be explained? I see that you posted this offer on "Big Data" category: how many rows are we talking about? In case the size of data set is relevant, cluster analysis might be problematic. Which clustering procedure are you willing to use? Do you want to use a hierarchical or an aggregative method? Finally, which R library do you have to run it?
I look forwad to be working with you. If you are interested, I am also fluent in Spanish - speaking and reading more than writing, because I don't use it very often.
