Thank you. I've tried what you're suggesting, at an earlier suggestion
from another respondent, and I don't find my variable in any of lists
ls() through ls(7).
Are you sure that "X" is really the name of a column in the dataframe?
names(All8Sites) will tell you all the names that are there.
I'm just going back to using R after being away from statistics for
several years. I'm thinking I might uninstall R, then reinstall it, and
redo my work so far (I've kept the commands elsewhere), and avoid using
"attach," as someone else has suggested.
It's not likely to be necessary to reinstall R, but it shouldn't hurt.

Two or three respondents asked for an example of my problem. Here's
what's happening to me now. I can't reproduce how I got to this point,

[1] "All8" "All8Sites" "A" "B" "C" "i" "n" "D" "F"
"X" is one of the variables in the data frame I attached in the third
command above, but it's not listed by >ls(). If I enter > X now, its
values ARE listed, but it's hiding somewhere. What is happening here?
How can I get the variables in that data frame listed when I attach it?
Use search() to see the search list. Your dataframe will likely be in
position 2. Use ls(2) to see the variables there.
