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 "p" or "o" the points are plotted;
if "l" or "o" they are joined by lines.
…
Additional graphics parameters used to plot the locations.
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.
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".
