# R plot set scale [closed]

I did some research and didn't find what I was looking for: I have a data set x = 10,100,1000 and y1, y2, y3 respectively, and I want to plot those points.

But what is happening is that in the x axis the values that are appearing are 10, 200, 400, 600, 800 and 1000. How can I set the scale so that it only appears the values I specified above? What I'm doing is:

y_values <- c(9, 9.6, 9.7, 9.8)
x_values <- c(10,100,1000)
plot(x_values, y_values)


Thank you.

You'll want to set axes=F, in the plot, the use the low-level axis function:

plot(x_values, y_values, axes=F)
axis(2)
axis(1, at=x_values, labels=as.character(x_values))
