The function will use the label of a placeholder to find the corresponding location.
ph_location_label(ph_label, newlabel = NULL, ...)placeholder label of the used layout. It can be read in PowerPoint or
with function layout_properties() in column ph_label.
a label to associate with the placeholder.
unused arguments
The location of the bounding box associated to a placeholder within a slide is specified with the left top coordinate, the width and the height. These are defined in inches:
left coordinate of the bounding box
top coordinate of the bounding box
width of the bounding box
height of the bounding box
In addition to these attributes, a label can be
associated with the shape. Shapes, text boxes, images and other objects
will be identified with that label in the Selection Pane of PowerPoint.
This label can then be reused by other functions such as ph_location_label().
It can be set with argument newlabel.

ph_location_fullsize(),
ph_location_left(),
ph_location_right(),
ph_location_template(),
