Simulation Runs on Rstudio cloud but fails when run locally

[Jeankwizera]

I am experiencing a challenge with simulating dispersal using rangeshiftR I would like some assistance to understand this.

I set up a simulation in "Rstudio Cloud" and the experiment runs successfully and returns the "results" I need.

However, the exact experiment fails with the following error when I run it in "Rstudio locally":

---

Run Simulation(s) with seed 13976 ...
LandscapeFile headers OK: /Users/ ... /Inputs/climate_suitability.asc
Species Distribution map headers OK: /Users/ ... /Inputs/news_location.asc
At (x,y) = 14,23 :
*** Corrupted file stream in /Users/kwizera.jvk/Desktop/KWIZCONSULT/Range dispersal simulation/Inputs/climate_suitability.asc
Too few entries? Unsuppoerted file encoding? (You might try to use a different one, like UTF-8.)

Error reading landscape 0 - aborting

This is the link to the "Rstudio cloud project" for assistance.

I am working with : R version 4.2.0 (2022-04-22) -- "Vigorous Calisthenics"

and:
RStudio 2022.02.2+485 "Prairie Trillium" Release (8acbd38b0d4ca3c86c570cf4112a8180c48cc6fb, 2022-04-19) for macOS

I would like to be able to run the experiment on my local machine as well without the error. Thankyou

Hi there,
When loading and writing the climate suitability to file you use probabilities ranging 0-1. However, RangeShiftR expects percentage value 0-100%. Thus, you code in line 44 should look like this:

raster::writeRaster(round(AllData2a*100), format="ascii", filename = "Inputs/climate_suitabilitya", NAflag = -9, overwrite = T, bylayer = T, datatype = "INT2U")

Best,
Damaris
