Graphical Input
Description
This is an alternative to the locator
function. It contains a workaround for a bug that occurs in
RStudio.
Usage
spatstatLocator(n, type = c("p", "l", "o", "n"), ...)
Arguments
n |
Optional. Maximum number of points to locate. |
type |
Character specifying how to plot the locations.
If |
... |
Additional graphics parameters used to plot the locations. |
Details
This is a replacement/workaround for the locator
function in some versions of RStudio which do not seem to
recognise the option type="p".
See locator for a description of the
behaviour.
Value
A list containing components x and y which are vectors
giving the coordinates of the identified points in the
user coordinate system, i.e., the one specified by par("usr").
Software Testing
Programmers may like to know that
code which depends on spatstatLocator
can be tested in a non-interactive session,
if the coordinates are previously queued using
queueSpatstatLocator.
