I discover last week the R software statistics programm, I have a small 
 questions, When we generate a bivariate normal distribution is it 
 possible to plot the generate distribution.
 The second one if there is a code to generate a bivariate student 
 distribution. 
 If yes i would ask you gratefully a help.

 Thank you very much

Yes,

For the bivariate normal distribution and the T distribution, use the
package: mvtnorm.
And for a 3D graphical representation use the command "barplot2" within the
package: gregmisc.

Both packages are available for Windows and Linux (you do not detail which
OS you use)...

Hope it helps.

Carlos Ortega.

Yes, although I'd recommend persp() or contour() (in base R) instead of 
barplot2() if you're going to plot bivariate *continuous* densities.
