Hello,
You must install the appropriate package(s). Try, for instance,
install.packages('rugarch') # do this only once
And then, every time you start an R session, if you want to use it,
library(rugarch) # do this every R session
To know more, try
help('rugarch')
vignette(package = 'rugarch')
vignette('Introduction_to_the_rugarch_package', package = 'rugarch')
The first 'vignette' instruction gives you a list of available
vignettes, the second one opens the vignette file in a new window.
Hope this helps,
Rui Barradas

Best.
