Graphic problem

[Palantir]

Hi, I'm beginning on R studio. I imported a file with average annual temperatures from 1985 to 2005. I wanted to make a curve of the evolution of these temperatures as a function of time with the following function: plot.ts(clim3$Date,clim3$Temp, xlab="Year", ylab="Temperature").
Here comes the problem (picture). The curve is ok but I don't know how to remove the numbers in the middle. I would only like the curve with points instead of the numbers. Do you have an idea? thank you so much.

x <- seq(1:12)
y <- c(4.4,4.4,6.6,8.5,11.7,14.5,16.7,16.4,14.0,10.7,7.1,4.6)
plot(x,y,type = "l")
