Build a path under the study root

Source: R/study_paths.R
sas_path.Rd

Joins its arguments onto the study root. A first component naming a logical study directory is resolved through the study's numbered or legacy layout. Other components are passed through unchanged. Use this instead of any literal path: the same study is mounted at different absolute paths on the analysis server and on a laptop.

Usage

sas_path(..., start = getwd())

Arguments

...

Character. Path components, passed to file.path().

start

Character. Directory to start the upward walk from. Defaults to getwd().

Value

Character(1). The joined path. It is not checked for existence.

root <- file.path(tempdir(), "sas-path-example")
dir.create(file.path(root, "datasets"), recursive = TRUE,
           showWarnings = FALSE)
yaml::write_yaml(
  list(study = "Example", built = "example.sas7bdat"),
  file.path(root, "_study.yml")
)
sas_path("datasets", start = root)
#> [1] "/tmp/RtmpAxnHxw/sas-path-example/datasets"
unlink(root, recursive = TRUE)
