Render a lineage graph

Source: R/lineage.R
lg_plot.Rd

Renders the lineage graph returned by lg_lineage() as an interactive inline widget (using DiagrammeR if installed), or writes the DOT source to a file for rendering with Graphviz externally.

Usage

lg_plot(lineage, output = NULL)

Arguments

lineage

An lg_lineage object from lg_lineage().

output

Character or NULL. File path for DOT output (e.g. "pipeline.dot"). When NULL (default), renders inline using DiagrammeR::grViz() if available, otherwise prints the DOT source to the console.

Value

The lg_lineage object, invisibly.

Examples

if (FALSE) { # \dontrun{
lg_start()
pts <- lg_tag(data.frame(USUBJID = c("P01","P02"),
                          eligible = c(TRUE, FALSE),
                          stringsAsFactors = FALSE),
              dataset_id = "PATIENTS")
lg_filter(pts, eligible, reason = "Not eligible")
lin <- lg_lineage()
lg_plot(lin)
lg_end()
} # }
