Extracts PolyData from a PolySet. Columns for the
PolyData include those other than PID, SID,
POS, oldPOS, X, and Y.
extractPolyData (polys)
polys |
PolySet to use. |
This function identifies the PolySet's extra columns and
determines if those columns contain unique values for each
(PID, SID). Where they do, the (PID, SID)
will appear in the PolyData output with that unique value.
Where they do not, the extra column will contain NAs for that
(PID, SID).
PolyData with columns PID, SID, and any extra
columns.
#--- create a PolySet with an extra column
polys <- data.frame(PID = c(rep(1, 10), rep(2, 10)),
POS = c(1:10, 1:10),
X = c(rep(1, 10), rep(1, 10)),
Y = c(rep(1, 10), rep(1, 10)),
colour = (c(rep("green", 10), rep("red", 10))));
#--- extract the PolyData
print(extractPolyData(polys))
