I have never worked with R before so I am
sorry if this is a bad question but I've
tried and tried ( all day ) and I can't figure this
problem out. I have the code below and I included the
data file as an attachment.
 
The code works in term of reading in the data
correctly but when the graph gets
created, the xaxis is really strangely/incorrectly
labelled. I have been trying
to understand this Posixct stuff in R but
I think this is where my knowledge is lacking and is maybe causing the
problem ?
Thank you very much.
 
I am using R in windows but through cygwin if that matters
but I doubt it does. Thanks again.

The attachment did not come through.

Look at R News 4/1 in general for info on dates and times and
if you still have a problem repost running this and placing its
output into the body of your post so we can see what your
data look like.

   Lines <- readLines(myfile)  # read in lines without parsing them
   dput(head(Lines))  # display first few lines in a way easy to read back in
