plot(x,y xlab=NULL,ylab=NULL) but labels still visible.

Labels are still present on graph render, their names are x and y  
that is the
same as I used on the variables to supply data for chart. How to get  
rid of
them.

The term "labels" as used in functions is different than the graphical  
objects affected by xlab and ylab. Those are really "titles"

?title

?plot.default  # which you should have consulted while you were using  
the help(plot) information.

Use one of "axes", "xaxt" or "yaxt" To indicate both or which axis to  
suppress.

here's the code

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=NULL,yaxt=NULL, xlab=NULL,ylab=NULL)

and x and y are still visible

?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="")

If you just want to remove both axis titles (xlab and ylab),
use plot(...., ann = FALSE).

If you want both axes to be free of ticks, etc, use
plot(...., ann = FALSE, axes = FALSE). This will also
remove the 'box' around the plot; you can add that
back with

  plot(....)
  box()

It's useful to study the documentation for ?plot.default to
which you are directed by ?plot.
