On this Picostat.com statistics page, you will find information about the PatentsHGH data set which pertains to Dynamic Relation Between Patents and R\&D . The PatentsHGH data set is found in the Ecdat R package. You can load the PatentsHGH data set in R by issuing the following command at the console data("PatentsHGH"). This will load the data into a variable called PatentsHGH. If R says the PatentsHGH 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 PatentsHGH R data set. The size of this file is about 161,754 bytes. ## Dynamic Relation Between Patents and R\&D## Descriptiona panel of 346 observations from 1975 to 1979
