pasteLoc | R Documentation |
Get coordinates on a plot by mouse-clicking.
pasteLoc(nb, digits = c(3, 3))
nb |
Number of positions. |
digits |
2 integer indicating the number of decimal places (respectively for x and y coordinates). |
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.
## Not run: 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")) ## End(Not run)
