[R] plotting functions with line width (lwd) as vectors

If I want to plot different widths of line segments or arrows
I have to program loops to plot each line apartly. Is that
right?
n <- 6
x <- 1:n
y <- rnorm(1:n)
q <- ( x %% 3 + 1 ) * 2
plot( x, y, cex=q )
for( i in 1:(n-1) ) lines( x[i:(i+1)], y[i:(i+1)], lwd=q[i], col=q[i] )
Would it not be possible to make plotting functions accept
vectors of line widths (as they accept vectors of colors
and vectors for cex)?
So you could say e.g.:
plot( x, y, cex=q )
lines( x, y, lwd=q, col=q )
