plot - 'x' and 'y' lengths differ in R -
i trying plot horizontal line in r, giving me error.
code:
w <- seq(1, 99, by=1) alpha <- 0.1 beta <- 0.001 u <- alpha*w -(beta/2)*w*w uprime <- alpha -(beta)*w udprime <- -beta utprime <- 0 plot(w,udprime,type = "l",main = "graph of u(w) versus wealth",xlab = "wealth",ylab = "utility function")
when plot function out, error:
error in xy.coords(x, y, xlabel, ylabel, log) : 'x' , 'y' lengths differ
why so? need guidance.
to plot horizontal line second derivative of wealth utility function, you'll need make sure udprime
has point every point w
. there's 2 ways this:
shortcut:
plot(cbind(w, udprime))
more "true math":
udprime = -beta * w^0
