plot: Decimal point accuracy on the axis
I have two columns of data, X and Y with each entry having 4 places of data after the decimal in both the vectors.
When I make the simple plot with plot(x,y) the axes have the data shown up to 2 decimal point accuracy. How do I change this to a 4 decimal point accuracy, on both axes?
I've added the example data below (inputData), that I have plotted using plot(inputData).
inputData=structure(list(X = c(33.73521973, 33.622022, 33.63591706, 33.58184488,
33.73027696, 33.76169838), Y = c(-112.2559051, -112.2396135,
-112.2345327, -112.2441752, -112.2463008, -112.3298128)), .Names = c("X",
"Y"), row.names = c(NA, 6L), class = "data.frame")
I would like a reproducible example on this above dataset, as well as part of the suggested answer.

Answer
One option is use axis to customize your labels. Here a comparaion between the same plot using the default axis of plot and using axis function.
op <- par(mfrow = c(2,1))
set.seed(1)
rr <- rnorm(5)
plot(rr, 1:5, frame.plot = TRUE)
plot(rr, 1:5, axes = FALSE, frame.plot = TRUE)
my.at <- round(rr,4)
axis(1, at = my.at, labels = my.at)
