Validate a VISTA object — validate

Performs structural and metadata contract checks on a VISTA object. Use level = "core" for invariants that all VISTA objects must satisfy, or level = "full" to additionally validate method-specific metadata used by advanced workflows.

Usage

validate_vista(x, level = c("core", "full"), error = TRUE)

Arguments

x: A VISTA object.
level: Validation depth. One of "core" or "full".
error: Logical; if TRUE, aborts on validation failures. If FALSE, returns the validation report and emits a warning when issues are found.

Value

Invisibly returns a list with fields valid, level, and issues.

Examples

mat <- matrix(rnorm(60), nrow = 10)
rownames(mat) <- paste0("gene", seq_len(nrow(mat)))
colnames(mat) <- paste0("sample", seq_len(ncol(mat)))
se <- SummarizedExperiment::SummarizedExperiment(
  assays = list(norm_counts = mat),
  colData = S4Vectors::DataFrame(
    cond = rep(c("A", "B"), each = 3),
    row.names = colnames(mat)
  ),
  rowData = S4Vectors::DataFrame(
    gene_id = rownames(mat),
    row.names = rownames(mat)
  )
)
v <- as_vista(se, group_column = "cond")
validate_vista(v)
