Get coordinates on a plot by mouse-clicking.

pasteLoc(nb, digits = c(3, 3))

Arguments

nb

Number of positions.

digits

2 integer indicating the number of decimal places (respectively for x and y coordinates).

Value

A list of coordinates. Note that if you don't put the result in a variable, it returns as the command text for generating the list. This can be useful to get coordinates by mouse-clicking once, but then using the code for convenience and reproducibility.

Examples

if (FALSE) { plot(runif(20, max = 5000)) # note the negative number for the rounding of $y coord <- pasteLoc(3, digits = c(2, -1)) text(coord, c("a", "b", "c")) }
