Hello R-Helpers..
I am still new in R and I have the following question..
I am applying the function chull on a 2D dataset and have the convex hull
nicely
calculated and plotted.
Do you know if there is a way to extract the coordinates of the line created
from the connection of the chull data
Hello,
I'm not sure i got your question right, but i think the whole point is
to find the equation of a line which passes by two points

?chull
states:
Value:
An integer vector giving the indices of the points lying on the
convex hull, in clockwise order.
therefore (see Example in ?chull) you have the end points of each line
segment from which you can compute the equation of each line segment.
Since the precision

Or see a basic geometry book, where you will find a formula such as:
(x-x1)/(y-y1) = (x2-x1)/(y2-y1)
for the equation of a line
