Hello,
Another possibility is to use argument 'data' explicitly:
A<-lm(GandW ~ Authocracy, data = Data)
Hope this helps,
It's not going to. The line parses very nicely as written, with or
without naming the argument.
The specific error the poster was getting only happens when you have
an input that doesn't parse. I have been having trouble reproducing
that error message but finally managed it by using that weird 'hook'
character in the top-left of my keyboard:
z¬1
Error: unexpected input in "z?"
- which makes me think the link I pointed to about Macs mashing <-
into a single arrow character is the kind of thing that is happening.
I didn't see such behavior here and have never observed it in my use
of a Mac. If you remove the non-printing "¬" characters coming from
ill-behaved editors on other OSes using text editor, generally things
will proceed normally.
We wait....
I suppose we do, but in my experience, that problem on a Mac arises
from copy-pasting from web postings from PC sources. Some of the
problem characters such as the "¬" from the IBM end-of-line heritage
are non-printing on the Mac console. (Do they print on the Linux
consoles?. I use Text Wrangler which has a handy ZapGremlins menu
choice.
