You should set environment variables in the environment, not from a
program. See rw-FAQ Q2.15 (and you may be able to set them in Eclipse
before it starts R).

The code I posted does work if you use it as I explained, not
as you changed it. Executing strings is probably not a very
R-ish thing to do but if that's your aim use eval and parse:
s <- "iris["iris$Sepal.Width > 4,]"
eval(parse(text = s))

I got another VAR question here and really appreciate if somebody would help me

To add to Brian's points (which you should heed!) -- you **may** find it
also useful to look at (possibly smoothed) residuals to compare lack of fit
from your alternative models. If any shows up, some subject matter knowledge
might lead you to choose one or the other of your models -- or neither.

Hello,
I am trying to create a dotplot, and have run into a couple of snags
with the finishing details. The below code creates the dotplot, but I
cannot figure out how to: 1) change the color of the CI bars to black,
not blue, 2) delete the horizontal dotplot lines, and 3) arrange the
