run_swmm error

[wujinshi]

hi, all I' m a new user of swmmr. When I want to run the test file, warning messages appeared. Is there any problem with the following code? thanks.

---

setwd("D:/") library(Rcpp) library(swmmr) library(tidyverse) library(purrr) library(ggplot2) library(broom)

inp_file <- read_inp("D:/Program Files (x86)/R-3.6.1/library/swmmr/extdata/Example1.inp", rm.comment = TRUE)

summary(inp_file) inp_file

inp_subcath <- inp_file$subcatchments inp_subcath

inp_path <- system.file("extdata", "Example1.inp", package = "swmmr", mustWork = TRUE) inp <- read_inp(x = inp_path) inp tmp_rpt_file <- tempfile() tmp_out_file <- tempfile() files <- run_swmm(inp = "D:/Program Files (x86)/R-3.6.1/library/swmmr/extdata/Example1.inp", rpt = tmp_rpt_file, out = tmp_out_file, exec = "D:/Program Files (x86)/EPA SWMM 5.1.013/swmm5.exe", stdout = TRUE, wait = TRUE)

Code seems ok. What is the warning message?

Warning messages: 1: In normalizePath(path.expand(path), winslash, mustWork) : path[1]="D:/Program Files (x86)/R-3.6.1/library/swmmr/extdata/Example1.rpt": system can not find files. 2: In normalizePath(path.expand(path), winslash, mustWork) : path[1]="D:/Program Files (x86)/R-3.6.1/library/swmmr/extdata/Example1.out": system can not find files

Code seems ok. What is the warning message? Are there errors because my file path does not exist .rpt files and .out files? However, how can I have not run the file yet? I do not quite understand this. Can you give me some advice? thanks.

Could you please check if you've set the path to your inp file and to your swmm5 executable correctly?

library(swmmr)

inp_file <- system.file("extdata", "Example1.inp", package = "swmmr", mustWork = TRUE)

file.exists(inp_file)
#> [1] TRUE

exec <- "D:/Program Files (x86)/EPA SWMM 5.1.013/swmm5.exe"
file.exists(exec)
#> [1] FALSE

exec <- "/usr/local/bin/swmm5"
file.exists(exec)
#> [1] TRUE

tmp_rpt_file <- tempfile()
tmp_out_file <- tempfile()

run_swmm(inp = inp_file, rpt = tmp_rpt_file, out = tmp_out_file)

Does it work now?

Hi, thanks for attention! I run your code in RStudio, the return value as follow:

exec <- "D:/Program Files (x86)/EPA SWMM 5.1.013/swmm5.exe" file.exists(exec) [1] TRUE Does it means that the path of swmm5 executable is correct?

Hi，Mr. Dleutnant Do you have any good suggestions for my model running error? So much thanks to you. Best regard, Jinshi

[dleutnant]

@wujinshi Yes, if you double check with file.exists your path to swmm5.exe should be fine. Also, could you please check that the model itself runs without complication (sometimes paths to rainfall time series need to be updated...), i.e. please run the model with the GUI of EPA's SWMM.

any news?
