Usage

emii_get_lymph_nodes_statd(df)

Arguments

A dataframe containing patient data with lymph node information

Value

A dataframe in long-format with one row per positive lymph node, including recoded anatomical position descriptions

Examples

emii_data <- load_embrace_ii()
ln_data <- emii_get_lymph_nodes_statd(emii_data)
} # }
