Hi:
In addition, the sos package is useful when you need to search for a function:
# install.packages('sos')
library(sos)
findFn('augmented Dickey-Fuller')
The results are sent to a Web page - this search identified the
adf.test() in the tseries package and the ur.df() function in the urca
package as well as several other potentially relevant functions in
other packages.
HTH,
Dennis
