check_duplicate_paths: Check for duplicated file paths

Description

The parent column in the manifest should not contain duplicated file paths. This function checks if any paths are duplicated.

Usage

check_duplicate_paths(
  data,
  success_msg = "No duplicate file paths detected",
  fail_msg = "Duplicate file paths detected"
)

Arguments

data

Data to check

success_msg

Message indicating the check succeeded.

fail_msg

Message indicating the check failed.

Value

A condition object indicating whether the data contains duplicated file paths in the parent column.

Details

It is possible for this function to return false negatives if the same path is written in different ways. For example, "~/file.txt" and "/Users/me/file.txt" will be treated as different paths even if they resolve to the same location on the user's machine. Because this function is typically run from a Shiny app without access to the user's filesystem, it is not possible to detect every possible duplicate path.

Examples

# NOT RUN {
manifest <- data.frame(
  path = c("/path/to/file.txt", "/path/to/file.txt"),
  parent = c("syn123", "syn123")
)
check_duplicate_paths(manifest)
# }
