R help - Aug 2012 - Making data in R available to Rcmdr

I'm an R newbie.  I'm trying to use Rcmdr to make a 3-D scatterplot of
data
from a two-independent-variable regression and of the regression plane.

The object "dat" in R contains the data:
> print(dat[1:20,])
         y     x1     x2
1   431.69  76.40 132.80

Rcmdr "knows" about dat.  If I click Data, New data set, and enter the
name
dat, Rcmdr won't let me use that name.  I get this message: "Data set
dat
already exists. Overwrite data set?"

However, I don't know how to make dat the active data set in Rcmdr.  Is that
possible?

Sorry if this is too basic.  Can't find an answer in "Getting Started
With
the R Commander" or on this list.

Todd

"Data -> New data set" allows you to enter a new data set in the R
data
editor; it doesn't give you access to a data set that's currently in
memory.
Assuming that dat is a data frame (and that it really has more than just one
line), you can access it either via "Data -> Active data set ->
Select
active data set", or by clicking the "No active dataset" button
in the Rcmdr
toolbar.

I hope this helps,
 John
