[R] SWATplusR package problems

[Wray, Nicholas M]

I am trying to get to grips with the SWAT+ hydrological model and with the package SWATplusR which is meant instantiate SWAT+ into R. I have going through the code supplied on this website https://github.com/chrisschuerz/SWATplusR/blob/master/vignettes/SWATplusR.Rmd

I can get so far, as shown beneath but then I get the error message also shown. I cannot see how to get any further


library(SWATdata)
library(SWATplusR)
demo_path<-"C:Documents"
demo_path
######
path_plus <- load_demo(dataset = "project",
                       version = "plus",
                       path = demo_path,
                       revision = 57)


q_obs <- load_demo(dataset = "observation")
q_obs
plot(q_obs, type = "l")####### Path to the subbasin shape file
sub_path <- load_demo(dataset = "subbasin", version = "plus")# Path to the subbasin shape file
riv_path <- load_demo(dataset = "river", version = "plus")
sub_path
riv_path
library(sf)
library(ggplot2)
sub <- read_sf(sub_path)
riv <- read_sf(riv_path)
ggplot() +
  geom_sf(data = sub) +
  geom_sf(data = riv, col = "royalblue", lwd = 0.75) +
  geom_sf_label(data = riv, aes(label = Channel)) +
  theme_bw()
q_sim_plus <- run_swatplus(project_path = path_plus,
                           output = define_output(file = "channel",
                                                  variable = "flo_out",
                                                  unit = 1))

The ggplot gives me a map but for the next line I get this error message:


Error: 'C:/swat_demo/swatplus_rev57_demo/time.sim' does not exist.

Where might this file be? I've tried searching for sources but cannot find anything. Thanks Nick Wray
