The SignatureHeatmap package enables signature classification of tumor samples by generating heatmaps using transcriptomic data.

At the moment, three different lists of signature genes are available in the SignatureHeatmap package:

  • the original list of basal/classical genes from Moffitt et al. 2015 for pancreatic ductal adenocarcinoma (PDAC) tissue samples
  • the updated list of basal/classical genes for PDAC tissue samples from Miyabayashi et al. 2020
  • the list of basal/classical genes from Tiriac et al. 2018 that has been developed for PDAC organoids

Citation

If you use this package for a publication, we would ask you to cite the following:

Deschênes A, King D and Tuveson DA. SignatureHeatmap: Heatmap using signature gene list and RNA-seq expression data. R package version 0.0.3, https://adeschen.github.io/SignatureHeatmap/

You can also replace the latest by the Research Resource Identifier (RRID), as example:

SignatureHeatmap version 0.0.4, RRID: SCR_022949

If you use one of the available signature gene list, the appropriate paper should be referenced.
