pluto is a compute cloud for exploratory financial data analysis. Jupyter notebooks created on pluto.studio are processed, uploaded to the creator's github account as plutons for sharing and versioning.
See pluto/presentation for the motivation behind it.
plutoR provides the data-model for accessing financial data-sets cached in the compute cloud. For examples, see the sample notebooks on pluto/docs-R.
