Yaml R Expressions

Using this query as a reference, I found a way to get R to parse the config file as an R expression. My config files now read:

  # Config paths
  first: !expr 'paste0("C:/Users/",Sys.info()[6], "/OneDrive/Science/experiments/first")'
  second: !expr 'paste0("C:/Users/",Sys.info()[6], "/OneDrive/Science/experiments/second")'
  third: ...

Then, when I read it in R, I use config = yaml::read_yaml('base/config.yaml', eval.expr=TRUE) and it works perfectly. It feels like a fragile solution, but so far it’s holding up.
