Linnorm is an R package for the analysis of RNA-seq, scRNA-seq, ChIP-seq count data or any large scale count data. It transforms such datasets for parametric tests. In addition to the transformtion function (Linnorm), the following pipelines are implemented:
Library size/batch effect normalization (
Linnorm.Norm)Cell subpopluation analysis and visualization using t-SNE or PCA K-means clustering or hierarchical clustering (
Linnorm.tSNE,Linnorm.PCA,Linnorm.HClust)Differential expression analysis or differential peak detection using limma (
Linnorm.limma)Highly variable gene discovery and visualization (
Linnorm.HVar)Gene correlation network analysis and visualization (
Linnorm.Cor)Stable gene selection for scRNA-seq data; for users without or who do not want to rely on spike-in genes (
Linnorm.SGenes)Data imputation (
Linnorm.DataImput).
Linnorm can work with raw count, CPM, RPKM, FPKM and TPM. Additionally, the RnaXSim function is included for simulating RNA-seq data for the evaluation of DEG analysis methods.
