DLBCL {ipred} | R Documentation

## Diffuse Large B-Cell Lymphoma

### Description

A data frame with gene expression data from diffuse large B-cell lymphoma (DLBCL) patients.

### Usage

    data("DLBCL")

### Format

This data frame contains the following columns:

DLCL.Sample

  DLBCL identifier.

Gene.Expression

  Gene expression group.

time

  survival time in month.

cens

  censoring: 0 censored, 1 dead.

IPI

  International prognostic index.

MGEc.1

  mean gene expression in cluster 1.

MGEc.2

  mean gene expression in cluster 2.

MGEc.3

  mean gene expression in cluster 3.

MGEc.4

  mean gene expression in cluster 4.

MGEc.5

  mean gene expression in cluster 5.

MGEc.6

  mean gene expression in cluster 6.

MGEc.7

  mean gene expression in cluster 7.

MGEc.8

  mean gene expression in cluster 8.

MGEc.9

  mean gene expression in cluster 9.

MGEc.10

  mean gene expression in cluster 10.

### Source

Except of `MGE`, the data is published at http://llmpp.nih.gov/lymphoma/data.shtml. `MGEc.*` is the mean of the gene expression in each of ten clusters derived by agglomerative average linkage hierarchical cluster analysis (Hothorn et al., 2002).
