I'm making a power point, but I can't seem to understand what an rId is or how it relates to src. I know src relates to source, but I'm not sure what Id is referring to. Is an Id just another way to call another function?
Error:
Error in external_img(material_shapes[stat_headers$directions$avg_lease_rate]) :
src must be a string starting with 'rId' or an existing image filename
Edit: Line emitting error
ph_with(value = external_img(material_shapes[stat_headers$directions$avg_lease_rate]), location = ph_location_label(ph_label = "Arrow Placeholder 4", newlabel = "Arrow 4"))
