Thanks to the three people who saw what I missed. I typed my
code in Libre Office as "<" followed by "-", and that program
converted those two characters into a single left arrow symbol.
I copied the commands from Libre into R without noticing that
that had happened. Wierd.

Hi David,
Your code is showing up here with an arrow symbols. If it's an actual
cut and paste, that's your problem: assignment in R is the two-character
<- and not an arrow symbol.Â
Otherwise your code looks fine.

I've just uninstalled and then reinstalled R on my windows 7 machine.
To test my understanding of data frames, I'm trying the following code.
(I plan to do other things with it, if it would only work.)
Here's the code, which seems pretty basic to me:
ls()
nums � c(1,2,3,4,5)
ltrs � c(“a�,�b�,�c�,�d�,�e�)
df1 � data.frame(nums,ltrs)
Here's what happens when I try to run it:
> ls()
character(0)
> nums � c(1,2,3,4,5)
Error: unexpected input in "nums \"
> ltrs � c(“a�,�b�,�c�,�d�,�e�)
Error: unexpected input in "ltrs \"
> df1 � data.frame(nums,ltrs)
Error: unexpected input in "df1 \"

Am I really misunderstanding the basics, or is there something
wrong with my installation?
David
