[R] question

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 at email.arizona.edu>"

Hope this helps,

Rui Barradas
