Hi all,

I have created following codes :

mat = cbind(c(0.000059710430,0.000023057380), c(0.000023057380, 0.00005971089)) set.seed = 1000
vary = runif(dim(mat)[1], 2000, 3000)
calc = function(mat, vary)

    {

     result = vector(length = (length(vary)+1))
     result[1] = sqrt(t(vary) %*% vary)
     for (i in 1 : length(vary))
        {
         result[(i+1)] = sum(vary)*sum(vary*mat[,i])
        }
     barplot(result)
     return(result)

    }

Now I want to present the plot in some interactive manner. I want to put a slider in the plot where user move the slider for the 1st element of the vector "vary" and automatically this result will be reflected at the plot window. I already gone through some examples of "tkrplot" library, however unfortunately could not figure out how i can apply them in my problem.

If anyone here explain me how to do that I would be grateful.
