To automatically install these views, the ctv package needs to be installed, e.g., via

install.packages("ctv")

library("ctv")

and then the views can be installed via install.views or update.views (which first assesses which of the packages are already installed and up-to-date), e.g.,

install.views("Econometrics")

or

update.views("Econometrics")
