On this Picostat.com statistics page, you will find information about the PatentsRD data set which pertains to Patents, R\&D and Technological Spillovers for a Panel of Firms . The PatentsRD data set is found in the Ecdat R package. You can load the PatentsRD data set in R by issuing the following command at the console data("PatentsRD"). This will load the data into a variable called PatentsRD. If R says the PatentsRD data set is not found, you can try installing the package by issuing this command install.packages("Ecdat") and then attempt to reload the data. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the PatentsRD R data set. The size of this file is about 59,467 bytes.
