Hi. Thanks to all who offered a solution with my problem with scan.
I read the helps pages but I did not understand the definition of 
'stream'. 
if I say:
my.file <- "c:/schrumpft.dat"
x <- scan(my.file,nline=1,what=...)
scan reads one line and closes the file but
my.file <- open(my.file,open="r")
x <- scan(my.file,nline=1,..._
then my.file is an already open file, i.e. a 'stream' and scan does 
not close it after reading a line and keep on reading lines on 
successive calls.
I know I am old and not up to date on computerese but I think that 
this behavior could be better explained in scan() help.
Thanks again to all those who offered help.
