Measurements of Forensic Glass Fragments
Description
The fgl data frame has 214 rows and 10 columns.
It was collected by B. German on fragments of glass
collected in forensic work.
Usage
fgl
Format
This data frame contains the following columns:
RI-
refractive index; more precisely the refractive index is 1.518xxxx.
The next 8 measurements are percentages by weight of oxides.
Nasodium.
Mgmanganese.
Alaluminium.
Sisilicon.
Kpotassium.
Cacalcium.
Babarium.
Feiron.
type-
The fragments were originally classed into seven types, one of which
was absent in this dataset. The categories which occur are
window float glass (WinF: 70),
window non-float glass (WinNF: 76),
vehicle window glass (Veh: 17),
containers (Con: 13),
tableware (Tabl: 9) and
vehicle headlamps (Head: 29).
