cytometryContinuous: The continuous cytometry network
In sparsebn: Learning Sparse Bayesian Networks from High-Dimensional Data

Description Usage Format Details References Examples

Data and network for analyzing the flow cytometry experiment from Sachs et al. (2005) [1]. This dataset contains the raw measurements from these experiments.

1	data(cytometryContinuous)

A list with three components:

dag An edgeList containing the consensus network (11 nodes, 17 edges).
data A data.frame with 11 variables and 7466 observations.
ivn A list specifying which nodes are under intervention in each observation. Compatible with the input to sparsebnData.

The dataset consists of n = 7466 observations of p = 11 continuous variables corresponding to different proteins and phospholipids in human immune system cells, and each observation indicates the measured level of each biomolecule in a single cell under different experimental interventions. Based on this data, a consensus network was reconstructed and validated, which is included as well.
