Data Sources on the Web


The following list of data sources has been collected and categorized for your convenience. The list has been limited to those for which there is a reasonably simple process for importing csv files. Most of the data sets listed below are free, however, some are not.

If an (R!) appears after source this means that the data are already in R format or there exist R commands for directly importing the data from R. (See for some code.)
