Hi. How can I write a matrix operation in an Excel Worksheet, using the R commands, for example, t (to calculate a transpose) or solve .

I wrote some like that:

operation function(x,y){
x\*t(y)
}
operation -> -RSetEval(A7;B7:B9)

3 3 -> Row 12
4 1 -> Row 13
12 -> =RApply(A10;A12:B12;A13:B13)

\*After arrow are comments

I want to multiplay the vector in the row 12 and the transpose of the vector in the row 13, but i'm obtaining 12 where I should be obtaining 15.

Pleae, i would thank a lot if some of you can help me with this matter.
