Computation of contour values - Speeding up computation
Dear R useRs,
i have the following code to compute values needed for a contour plot
############################################################
"myContour" <- function(a, b, plist, veca, vecb, dim)
{
tmpb <- seq(0.5 * b, 1.5 * b, length=dim)

z <- matrix(0, nrow=dim, ncol=dim)

for(j in 1:dim)
{
z[i, j] <- posteriorPdf(a=tmpa[j], b=tmpb[i],

binding rows from different matrices
Hello list,
I have 3 matrices with same dimension :
> veca=matrix(1:25,5,5)
> vecb=matrix(letters[1:25],5,5)
> vecc=matrix(LETTERS[1:25],5,5)
I would like to obtain a new matrix composed by alternating rows of these
different matrices (row 1 of mat 1, row 1 of mat 2, row 1 of mat 3, row 2
of mat 1.....)
I have found a solution to do it but it is not very pretty and I wond...
