[R] Two dimensional likelihood surface plot

[Gyanendra Pokharel]

Hi R users,
I am trying to plot two dimensional posterior likelihood surface. I have a
data like

para1     para2     likehood
.......      ........      ...........
.......      ........      ...........



I looked at contour plot but it needs a shorted values of parameters and a
matrix of likelihood values. Is there any way to get the plot? or how can I
change my likelihood values to a matrix for the function "contour"?

Any suggestions are appreciated.
