Hi All,
I am a new GRASS user and would like to pull horizon data for multiple
points off of a DEM. I have been able to use the grass console to
accomplish this but I will need to run thousands of points from a gridded
dataset. I was hoping to apply a function or loop in R to accomplish this
however I am getting the following error in R while listing parameters.
Using Windows 10, R x64 3.3.2, rstudio 1.0.136 in a Grass GIS session
*Section of code:*
library(rgrass7)
doGRASS("r.horizon", flags = c("d"), parameters = list(elevation =
"w001001",
direction = 0.0, step = 180.0,
coordinates = -155.447804131,19.3115222633,
file = "test_horizon1.csv"))
*Error:*
Error in doGRASS("r.horizon", flags = flags, parameters = parameters) :
Invalid parameter name:
>
Any suggestions would be most appreciated.
Thanks,
Heidi
