Interactive Data Visualisations
You could give the plotlypackage a try. You basically code up the plot you want first with ggplot2 and then call ggplotly() at the end, which will render an interactive version of it. You get zooming in on mouse selection for example and labels of points on hover. It has a pretty extensive documentation too. I can try and help you out with a specific example if you post some code. Another cool package you can check out is trelliscopejs. hth
