R help - Apr 2005 - pp-test in timeseries

Test for stationarity (pp-test). In R source code all other command executions I
understood, but how I am getting the ssqrtl value

ssqrtl <- .C ("R_pp_sum", as.vector(u,mode="double"),
as.integer(n),
                  as.integer(l), trm=as.double(ssqru), PACKAGE="ts")

please explain the above command.

Thanks in advance
Ramesh

Please read `Writing R Extensions' (and the posting guide, as you sent 
HTML mail).  As was once said here:

This is all documented in TFM. Those who WTFM don't want to have to WTFM 
again on the mailing list. RTFM.
