The celarefData package is a repository of a few public datasets that have been processed using the celaref package. It is cheifly used to hold example data that is used in the celaref package vignette - please refer to full examples there.
The data in this package is a series of data frames output from the contrast_each_group_to_the_rest function of the celaref package. That is, these are differential experession results (calculated using MAST Finak et al. (2015)), of each cell cluster versus the rest of the experiment.
For details and explanation see the celaref package vignette. The commands used to make these data files are also in the make-data.R file of this package.
Farmer et al. (2017) have published a survey of cell types in the mouse lacrimal gland at two developmental stages in paper (Defining epithelial cell dynamics and lineage relationships in the developing lacrimal gland). Only the more mature P4 timepoint is included.
Data:
The (‘Watkins2009’) ‘HaemAtlas’ (Watkins et al. 2009) microarray dataset of purified PBMC cell types was downloaded as a normalised table from the ‘haemosphere’ website: http://haemosphere.org/datasets/show (Graaf et al. 2016)
Processing for those data files via contrast_each_group_to_the_rest_for_norm_ma_with_limma is described in the vignette.
Data:
10X genomics has several datasets available to download from their website, including the pbmc4k dataset, which contains PBMCs derived from a healthy individual. The kmeans k=7 cell-cluster assignments were chosen. Source dataset available here: (https://support.10xgenomics.com/single-cell-gene-expression/datasets/2.1.0/pbmc4k)
Data:
In their paper ‘Cell types in the mouse cortex and hippocampus revealed by single-cell RNA-seq’, Zeisel et al. (2015) performed single cell RNA sequencing in mouse, in two tissues (sscortex and ca1hippocampus).
This data was download from the link provided in the paper: http://linnarssonlab.org/cortex
As described in make-data.R, both counts and cell annotations were parsed from this file: https://storage.googleapis.com/linnarsson-lab-www-blobs/blobs/cortex/expression_mRNA_17-Aug-2014.txt
