5 Issues

  • Requires many packages to be installed. Depending on your existing setup, it could take up to an hour to install everything
  • Packages visNetwork and rgdal may need to be installed manually for all code to work

Error:

Error installing package 'ps':
==============================
* installing to library 'C:/Users/djor8013/OneDrive - The University of Sydney (Staff)/En Health/air-health-sws-r-targets-main/renv/staging/1'
* installing *source* package 'ps' ...
** package 'ps' successfully unpacked and MD5 sums checked
** using staged installation
Warning in system("sh ./configure.win") : 'sh' not found
ERROR: configuration failed for package 'ps'
* removing 'C:/Users/djor8013/OneDrive - The University of Sydney (Staff)/En Health/air-health-sws-r-targets-main/renv/staging/1/ps'
Error: install of package 'ps' failed [error code 1]

Solution: Uncomment out help download function:

source("R/func_helpers/helper_install_pkgs.R")
install_pkgs(repos = getOption("repos"))

  Last error: The download destination specified is likely used by a sync client. Please choose another destination.

Solution:

  • Create destination folder for CARDAT mirroring that is not a sync client (e.g. on local computer)
  • Save _targets.R after doing this

Solution:

  • File path name too long
  • Shorten dir_cardat pathname in _targets.R
    • For example: remove “OneDrive - The University of Sydney (Staff)”

  Last error: error in evaluating the argument 'x' in selecting a method for function 'brick': Cannot create RasterLayer object from this file; perhaps you need to install rgdal first

Solution: Install and load package rgdal

  Last error: 'breaks' are not unique

Solution:
Attributable number for some scenarios can be very small – colourQuantile in r script viz_leaflet_an cannot handle these small numbers, will have quantile cutoffs with same break numbers.

Open viz_leaflet_an.R
Change:

pal1 <- colorQuantile(
    palette = "RdYlBu",
    domain = sf_an$attributable, n = 5, reverse = TRUE
  )

To:

pal1 <- colorNumeric(
    palette = "RdYlBu",
    domain = sf_an$attributable
  )

This creates a continuous pallet rather than a categorical palette.
