problem solution

This question is not clear. What do you mean by solution file? You can find documentation for individual datasets by typing a question mark (?) followed by the the name of the dataset.

Sample datasets are included in packages. There are several packages included with R that have some datasets. The source for those is in the source code for R [1].

There are also more than 16000 contributed packages, many of which have sample datasets, which would be in their source code [2].
