How to zoom in to raster plot (setting limits to raster)

Question

I have plotted an overlay map of hillshade and landslide susceptibilities. I would like to zoom in on a particular area of the plot.

landslide_raster_pred <-predict(ta,landslide_model, type = "response")

hillshade <- hillShade(slope_data, aspect_ratio, angle=45, 0)

overlay_map <- overlay(landslide_raster_pred,hillshade, fun=function(x,y){return(x*y)})    


dev_coordinate=data.frame(x=714717.7, y=9560497)

# Extract the susceptibility at the point of interest from the raster
dev_prediction <- extract(landslide_raster_pred, dev_coordinate)

# Plot the overlay map with the point of interest 
plot(overlay_map, main = "Landslide susceptibility and hillshade map", 
 xlab = "longitude",
 ylab ="latitude")
points(c(714717.7), c(9560497))

How can i zoom in on the area where the point is to show a better picture/resolution? Any help will be appreciated thank you.

Example data

library(raster)
f <- system.file("external/test.grd", package="raster")
r <- raster(f)
pt <- cbind(180000,331000)
plot(r); points(pt)

You can create an extent like this

s <- 500
e <- extent(pt[1]-s, pt[1]+s, pt[2]-s, pt[2]+s)

And then use that to plot like this

plot(r, ext=e)

Or like this

zoom(r, e)

You can also do this interactively, by drawing a rectangle on the plot

plot(r)
zoom(r, drawExtent())

Or

plot(r,  xlim=c(pt[1]-s, pt[1]+s), ylim=c(pt[2]-s, pt[2]+s))
