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 "p" or "o" the points are plotted; if "l" or "o" they are joined by lines.

...

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").
