Subject: Re: [R] x, y for point of intersection
The function crossing.psp() in the spatstat package might be of use.
Here's an excerpt from its help page:
crossing.psp package:spatstat R Documentation
Crossing Points of Two Line Segment
.
Thanks again to all who have answered and helped to solve my problem. I
certainly learned few new things.

Hi everyone,
I am trying to get a point of intersection between a
polyline and a straight line ….. and get the x and y coordinates of this

For exemplification consider this:
set.seed(123)
k1 -rnorm(100, mean=1.77, sd=3.33)

Crossing Points of Two Line Segment PatternsDescription:
Finds any crossing points between two line segment patterns.
Hi everyone,
I am trying to get a point of intersection between a
polyline and a straight line ….. and get the x and y coordinates of this point.
For exemplification consider this:
set.seed(123)
k1 -rnorm(100, mean=1.77, sd=3.33)
k1 - sort(k1)
q1 - rnorm(100, mean=2.37,
If it's a one off, the identify() function might be of help -- if you need
something algorithmic it's harder due to floating point stuff and sampling
frequencies. Let me know if that's the case.

Hi
afterwards the results need to be
translated back to the original coordinate system.
Thanks,
