r - How to perform sum of vector elements if it contains another vector? -

-

i have similar code in r gives warnings:

> require(pracma) # integral > v1 <- c(1, 2, 3, 4, 5) #some vector of unknown length > v2 <- c(6, 7, 8, 9, 0) #another vector of same length v1 # here want sum v1 & v2 elements, sum contains x argument > f <- function(x) x^(-2i) sum(v1 / (1 - v2 * x)^2) > integral(f, 1e-12, 1)  49: in v2 * x : longer object length not multiple of shorter object length 50: in v1/(1 - v2 * x)^2 : longer object length not multiple of shorter object length

i use r-studio debugging purpose, , see integral function pass vector f function.

i understand v2 vector , x vector. i'm don't know how make work without warnings. have tried put vectorize(x) in sum function, warnings still here.

how handle situation?

there 2 problems here. first need vectorize function. second function returns complex value (although argument real). can integrate complex functions using myintegrate(...) function in elliptic package.

library(elliptic) v1 <- c(1, 2, 3, 4, 5) v2 <- c(6, 7, 8, 9, 0)  f <- function(x) x^(-2i) * sum(v1 / (1 - v2 * x)^2) g <- vectorize(f) myintegrate(g, 1e-12, 1) # [1] -3173.272-8530.861i

i have draw ovals in java, , @ click change color. beginning tried change color after 20 ms, doesn't work. my code is: public class mycomponentnew extends frame { public graphics2d g2d; public mycomponentnew(string title) { super(title); setsize(400, 550); } @override public void paint(graphics g) { this.g2d = (graphics2d) g; this.g2d.setcolor(color.red); this.g2d.filloval(10, 55, 50, 100); } public void changecolor () { this.g2d.setcolor(color.blue); this.g2d.filloval(10, 55, 50, 100); } } and in class main method have: mycomponentnew m; m = new mycomponentnew("fereastra cu baloane"); m.setvisible(true); m.addwindowlistener(new windowadapter() { @override public void windowclosing(windowevent we) { system.exit(0); } }); try { thread.sleep(20); } catch(interruptedexception e) {} m.changecolor(); the color of oval remains red. ...
