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.

"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

Thanks for your help, John!

I don't know how I missed the Data, Active Data Set sequence.
