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"?
If the data are organized in a regular manner, then this might succeed:
with( df, contour( x=unique(para1), y=unique(para2)
z= matrix( likehood, length(unique(para1), length(unique(para2) )
) )
Any suggestions are appreciated. GP University of Guelph Guelph, ON [[alternative HTML version deleted]]
