The function edit is generic. These functions
are methods for spatial
objects of class "ppp", "psp" and "im".
The spatial dataset name is converted to a data frame or array,
and the text editor is invoked. The user can change the values of spatial
coordinates or marks of the points in a point pattern,
or the coordinates or marks of the segments in a segment pattern,
or the pixel values in an image.
The names of the columns of marks can also be edited.
If name is a pixel image, it is converted to a matrix
and displayed in the same spatial orientation as if
the image had been plotted.
Note that the original object name is not changed;
the function returns the edited dataset.
Object of the same kind as name containing the edited data.
