|R&D expenditures in all fields, including direct and recovered indirect costs, funded by all agencies of the Federal government.
Prior to 2003, the survey only requested R&D expenditures within science and engineering (S&E) fields, therefore this variable can be used for
any trend analyses including 2003 and beyond. For trend analyses involving years prior to 2003, please use the analysis variable Federally
Financed Higher Education R&D Expenditures for S&E.
