This depends on what you mean by 'output'. If you mean graphs, then you
can use x11() if you have X Window systems or windows() if you are  in
Windows OS.

 windows()
 plot(1:10)
 windows()
 plot(rnorm(1000))

Or you could use the mfrow option in par() to split the plotting window

 par(mfrow=c(1,2)
 plot(1:10)
 plot(rnorm(1000))

If your output is not graphical, then you can save to a file and compare
them or save it to a list/matrix in R.

> 2) In my function I make use of the Rcmdr package. But every time I use my  function and the Rcmdr package loads, I get the R-commander window and I have to delete it every time. So I wonder if there is a way to avoid R-commander window every time I load the Rcmdr package.

There is a function called mle.cp in the package wle. Not sure if this
does what you want.
