[R] question

Tue Mar 15 23:42:23 CET 2022

Hello,

RiverSmooth is not a function in package flowr it's a function in GitHub 
package PriorityFlow. This package is not on CRAN.

devtools::install_github("lecondon/PriorityFlow", subdir = "Rpkg")
library('PriorityFlow')

?RiverSmooth
RiverSmooth {PriorityFlow}	R Documentation
Apply smoothing to a DEM along a pre-defined stream network
Description
This function will smooth a DEM along a stream network. It requires 
pre-defined stream segments and subbasins which can be obtained using 
the CalcSubbasins function.

As for the error, I cannot say more than this (excet that the OP 
shouldn't write in all caps, like Ivan already said), I know nothing of 
this package. Try to contact

maintainer("PriorityFlow")
[1] "Laura Condon <lecondon using email.arizona.edu>"

Hope this helps,

Rui Barradas
