?par for valid xaxt and yaxt values. And unlearn the use of NULL for  
argument values. You generally are going to want to provide something  
(NA or "") and in R NULL is "nothing".

See if this is closer to what you wanted

x= c(1,5,7,3,4)
y= c(2,4,5,2,5)
plot(x,y,ylim=c(-20,20),xlim=c(min(x),max(x)), pch='X', col = rgb(0,  
0, 0,
0.5), xaxt="n", yaxt="n", xlab="",ylab="")
