check stage may fail when validation results are pushed into the repository

[zsigmas]

These chuncks are run during the checking stage.

val_param_rds <- "../inst/validation/results/val_param.rds"
val_param_rds_exists <- file.exists(val_param_rds)
if (file.exists(val_param_rds)) params <- readRDS(val_param_rds)

if (val_param_rds_exists) {
  res <- knitr::knit_child("../inst/validation/val_report_child.Rmd", quiet = TRUE, envir = environment())
  cat(res, sep = "\n")
} else {
  "No quality control results found"
}

If validation results are pushed in the repo an attempt to read those files will occur and because check happens on the installed package the path will be wrong.

Proposed solutions:

• Check that validation results are not pushed into the repositories
• Fail the check if validation results are found in the directory with a clear message. The message provided by the check is quite obscure by default.
• Include a control in qc.rmd that bypass these chunks when we are checking
