[R] Regarding pp.plot(){CircStats}

[Ravi Malayambakkam-n]

	      [message needed manual approvement:
	       it had a single line "help"  -- MM ]

I have a table containing two columns and some 600 rows.  The first column 
is a time series in the sense contains the amount of time the model that i
am studying stays in a particular state(ie sojourn time).  I 
extract the contents of the table using read.table. and extract the
first column from the table as follows.
	ft <-read.table(<filename>)
	firstcol <-ft[1].
When I pass firstcol as a parameter to pp.plot(firstcol) I get the 
following error :
Error in if (abs(term) < acc) flag <- "false" : 
         missing value where logical needed
 
Can anyone tell me where the mistake is.

end.
