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 <lecon...@email.arizona.edu>"
Hope this helps,
Rui Barradas

is where you can post questions about *their* products.
2. HOWEVER... your query seems to be related to a special (not
standard) R package, not RStudio, specifically the 'flowr' package.
This general r-help list is not usually a good place to post queries
about such specific packages -- there are thousands of them! Maybe you
will get lucky and someone here will be able to help you. But it is
recommended in the posting guide (linked below) that a better option
is to contact the package maintainer, which you can find via the:
maintainer("flowr")
command at the R console prompt.
Hope this helps.

reason of it but all i done didnt fix it.
I have a function of a package named priority flow as bellow:
RIVSMOOTH=RIVERSMOOTH(DEM=TRAVHS$DEM, DIRECTION=TRAVHS$DIRECTION,
MASK=FARWATERSHED.MASK,RIVER.SUMMARY=SUBBASIN$SUMMARY,RIVER.SEGMENTS=S
UBBASIN$SEGMENTS,BANK.EPSILON =0.01,RIVER.EPSILON =
0,D4=C(1,2,3,4),PRINTFLAG = T)
and all needed inputs are available but when i run it give me the
bellow
error:
[1] "No terminal river segments provided, not adjusting DEM"
Error in RiverSmooth(dem = travHS$dem, direction = travHS$direction,
mask = FARwatershed.mask, :
object 'active' not found
I dont know what active object is here? but all other objects are here
available.i also assighned this needed inputs in different object
forinstance AA=travHS$dem and then defined AA in the function but it
return error again.
this is summary of two dataframe that included needed data:
SUMMARY(SUBBASIN)
Length Class Mode
segments 4200 -none- numeric
subbasins 4200 -none- numeric
RiverMask 4200 -none- numeric

-none- numeric mask 4200 -none- numeric marked 4200 -none- numeric
step 4200 -none- numeric direction 4200 -none- numeric basins 4200

this is part of my work and i really stumbled in it. Is there any one
