Dear Tristan,
no R solution, but maybe a starting point: You can check out the Grass
GIS tool v.net.distance
(https://grass.osgeo.org/grass72/manuals/v.net.distance) what should
help you. GRASS tools can also be integrated in R via the rgrass7 package.
Good luck!

Hi,
I'm a R new user and this is also my first post on this mailing list.
I'm currently working on several project with R and I still have not found
a solution for one :
To be concise I'm working with shapefiles representing on a delimited area :
- sewage plant (SpatialPointsDataFrame)
- water quality measurement stations (SpatialPointsDataFrame)
- hydrographic network (SpatialLineDataFrame)
What I want to do is to calculate the distance between each sewage stations
and each measurement stations following the river route.
For now, I have snapped all my points on the river and created a new layer
with both type of point (sewage stations and measurement) in order to split
the lines by the point layer.
I'm looking for a way to get a kind of distance's matrix.
Does anybody has already worked on a similar project ? I'm kind of lost
with all the R packages and functions so any pistes or proposals or idea
will be greatly appreciate.
PS : As I said this is my first post. If I'm not clear about my issue or if
I'm not respecting any posting rules don't hesitate to tell me about.
Cheers
