Access dsomop_result elements with backward compatibility

Custom $ operator for dsomop_result objects. Top-level fields (per_site, pooled, meta) are returned directly. Any other name falls through to the per_site list, allowing backward-compatible access patterns such as result$server_a instead of result$per_site$server_a.

Usage

# S3 method for class 'dsomop_result'
x$name

Arguments

x

A dsomop_result object.

name

Character; the element name to access.

Value

The requested element: a top-level field, or the matching entry from per_site, or NULL if not found.

Examples

if (FALSE) { # \dontrun{
res <- ds.omop.achilles.status()
res$per_site          # top-level access
res$server_a          # falls through to per_site[["server_a"]]
} # }
