I have looked at various sources for data, but I am not experienced in looking for such data sets. I want a dataset that has age, weight, height, and sex across many ages. I would prefer that it have no correlation to disease, region, or any factors that might affect the data and how it can be interpreted. I need a large amount of data. If the dataset has more than the parameters I am looking for, that is fine, I can filter it out. I do, however, need to be able to have the data as a CSV, JSON, or XML file so that I can use to train a neural network. The language is R, so if there is a library specifically available for R, please link me to a page that shows this. The dataset does need to be very large, preferably more than 5,000 entries, but I only need about 2,500 entries. Thank you for any help you are able to provide.
