ave answered and helped to solve my problem. I
certainly learned few new things.

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 PatternsDescription:
Finds any crossing points between two line segment patterns.

(edited out excessive white space)
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=1.7
afterwards the results need to be
translated back to the original coordinate system.
Thanks,
Monica

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 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, sd=0
11 matches
