Validates a data set for use with rollup()

Source: R/rollup.R
validate_ds.Rd

validate_ds() ensures that a data set contains the same identifiers as a specified tree and that elements of the data set corresponding to leaf vertices in the tree satisfy a user-specified predicate.

Usage

validate_ds(
  tree,
  ds,
  get_keys,
  get_prop,
  op = function(x) is.numeric(x) & !is.na(x)
)

Arguments

tree

igraph directed graph that is a valid single-rooted in-tree and whose vertex names are keys from the data set

ds

data set to be updated; can be any object

get_keys

function to get keys of the data set called as get_keys(ds)

get_prop

function to get the property value to validate for leaf element with id l, called as get_prop(ds, l)

op

logical function to test return value of get_prop() (default is.numeric()); returns TRUE if OK

Value

TRUE if validation succeeds, halts otherwise

Examples

validate_ds(wbs_tree, wbs_table, function(d) d$id, function(d, l) d[d$id == l, "work"])
#> [1] TRUE
