Dear All:
I am trying to plot the function f(x) = x^(1/5) for x=seq(-2,2,0.01). It
give me only the plot of f(x) for the positive part of x. I checked the
values of f(x), it is NaN for all negative values of x.
*this is my code:*
x<-seq(-2,2,0.01)
y<- (x)^(1/5)
plot(x,y, type="l", lwd=3, xlab = " ", ylab = " ", col="blue")
abline(v=0, col="gray", lty=2, lwd=3)
abline(h=0, col="gray", lty=2, lwd=3)
any help will be appreciated.
with many thanks
steve
