Examples for help / check description

[florianhartig]

Add examples in help for all datasets in https://github.com/TheoreticalEcology/ecodata/tree/master/EcoData/inst/examples

Good things for help would be

a) an overview plot or str() about the variables
b) possibly (but not always necessary) a very simple model fit

Also, check the description of all datasets. For example, titanic seems to be incomplete. Description should be as complete as possible, and you should look in particular at

• All variables described?
• Example R code?
• Source of the data (please also check, as far as possible, if re-distribution is OK)
