[R] Display of data points in the Scatterplot
Respected R forum I am learning R and relatively quite new to R. I am generating a scatter-plot as given below. (My actual table is much larger). # Sample data frame y = c(20, 23, 17, 31, 68) x = c(200, 300, 400, 500, 600) plot(x, y, type = 'l') If I plot this scatter-plot in excel, the data values are displayed if I place the cursor at some desired place of the graph. E.g. if I place the cursor say at the point (400, 31), then the value (400, 31) is displayed. My question is (A) once I plot a graph in R, is it possible to display a particular (x, y) co-ordinate by placing the cursor there? (B) Suppose I have 100 pairs of (x, y ). then is it possible to display in the graph (irrespective of the curosr position) the values of (x, y) corresponding to say 10th, 20th, 30th, 40th etc. observations in the graph.
