question

Hello,

You forgot to cc the list.

Like the posting guide says and Like I said, when you have doubts about non base or recommended packages you should contact the package maintainer. She is the best placed person to answer questions on it.

Thanks for your answer. Yes I installed priorityflow package and I just pasted this part that returned error. I didn't get what is the mean active object to decide how to fix it. While all needed objects for running it are available. All other part running properly

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")

Hope this helps,

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.

hello everyone

I faced an problem in Rstudio version 4.1.2 and while i am new in R
and Rstudio, but i search alot in internet and have thaught about the
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
summary 98 -none- numeric SUMMARY(TRAVHS) Length Class Mode dem 4200
-none- numeric mask 4200 -none- numeric marked 4200 -none- numeric
step 4200 -none- numeric direction 4200 -none- numeric basins 4200
-none- numeric

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

I really appreciate it.
