(Just learning R) I have this vector: v <- c(1:10) Now, I want to multiply each element of that vector with a scalar value multiplied with its index: vm <- v * scalar * indexOfCurrentElementOf_v Is that possible without using a loop?

I tried to create voronoi objects by using following code. > library(tripack) > x <- rnorm(10) > y <- rnorm(10) > plot(x,y) > v<-voronoi.mosaic(x,y) > plot(v) But from here, I could not create polygons. Of course, I know
