[R] Using a for loop

[Joshua Wiley]

You should read the posting guide again (at all?).  Among other
things, it suggests you should show what you have tried doing that did
not work (worst case it shows us you tried to figure it out on your
own before asking other people to freely give their time to solve your
problems, at best case, we only need to minimally tweak your code to
get you up and running and save time duplicating what you already did
that was close to right but not quite).  Did you try anything to get 1
to 65 in x and 66 to 130 in y?

Look at the documention for the extraction operator, which you can
access by typing at the console: ?"["

? typically brings up documentation, though you normally do not need
to quote function names, [ is special so it needs quotes around it.
By leaving the row index empty (that's the part before the comma), you
are selecting all rows.  If you only want to select rows 1 to 65, try:

1:65

which suggests

normtemp[1:65, 1]
normtemp[66:130, 1]

finally leading us to:

x <- normtemp[1:65, 1]
y <- normtemp[66:130, 1]

Thank you for indicating the package you are using and providing an
easy data example, though.

I hope this helps.

Cheers,

Josh

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ link to the
posting guide I mentioned
