Many thanks to everyone who contributed to this discussion. It looks
like plotly and dygraphs both work well for zooming plots with
thousands of points (and many other things).
Thanks again, I appreciate your help.

Hi Robert,
Maybe you can use something simple like this:
zoomInScatterPlot<-function(x=NULL,y,...) {
if(is.null(x)) x<-1:length(y)
plot(x,y,...)
xylim<-par("usr")
boxed.labels(xylim[1]-diff(xylim[1:2])/20,
xylim[3]-diff(xylim[3:4])/10,"Done")
xy1<-locator(1)
done<-FALSE
while(!done) {

Plotly and dygraphs support this.

Hi,
I am making some plots with plot() which have a fair number of points
(thousands) and I would like to be able to interactively select a
region of the plot and zoom in on it. I tried the zoom package which
has the function zm() but I found that it was unworkably slow to
refresh the display. I
