[R] A question about using function plot

Hello, everyone! I have spent two hours to get what I wanted in a simple situation and have not been successful. The set up is extremely simple

x = c(1,2,4,8)
y = c(1,2,3,4)
plot(x, y)

What I need, however, is for the 4 points of 1,2,4,8 to be spaced evenly, not by their numerical scale. Also, there should not be any other values such as 5,6,7 marked on the axis.

So I tried the following

x = c("1","2","4","8")
y = c(1,2,3,4)
plot(x, y)

No help at all.

Anyone can point me to the right way? Thank you very much.
