iLICOB

iLICOB: an R package for exploring LICOB resource.

Requirements

install.packages(c("pacman"))

Install

devtools::install_github("wu-yc/iLICOB")

Quick Start

iLICOB generally supports two main functions: (1) Predict drug response based on omics profile; (2) Query gene of interest.

1. Load packages and demo data

The demo data is a subset of LICOB omics data and TCGA-LIHC RNA-seq data (Cell. 169.7(2017):1327-1341).

#load packages
library(iLICOB)
library(pacman)
p_load(DALEX,caret,tidyverse,elasticnet)

#load data
load(file = system.file("data", "data_ilicob_org", package = "iLICOB"))
load(file = system.file("data", "data_ilicob_tissue", package = "iLICOB"))

2. Predict drug response based on omics profile

# 1 - Tissue demo data (TCGA-LIHC RNA-seq data)
mat = data_ilicob_tissue[[3]]
AUC.predicted = iLICOB_predict(input.mat = mat, input.type = "Tissue", input.omics = "RNA")

# 2 - Organoid demo data (LICOB RNA-seq data)
mat = data_ilicob_org[[3]][[1]]
AUC.predicted = iLICOB_predict(input.mat = mat, input.type = "Tissue", input.omics = "RNA")

# 3 - Organoid demo data (LICOB Proteome data)
mat = data_ilicob_org[[3]][[2]]
AUC.predicted = iLICOB_predict(input.mat, input.type = "Organoid", input.omics = "Protein")

# 4 - Organoid demo data (LICOB CNV data)
mat = data_ilicob_org[[3]][[3]]
AUC.predicted = iLICOB_predict(input.mat, input.type = "Organoid", input.omics = "CNV")

# 5 - Organoid demo data (LICOB Methylation data)
mat = data_ilicob_org[[3]][[4]]
AUC.predicted = iLICOB_predict(input.mat, input.type = "Organoid", input.omics = "Methylation")

# 6 - Organoid demo data (LICOB Mutation data)
mat = data_ilicob_org[[3]][[5]]
AUC.predicted = iLICOB_predict(input.mat, input.type = "Organoid", input.omics = "Mutation")

input.mat is a data.frame object of omics profile.

input.type is the data type of input matrix. It supports "Tissue" and "Organoid". The default value is "Tissue".

input.mat is the omics type of input matrix. It supports "RNA", "Protein", "CNV", "Methylation", and "Mutation". The default value is "RNA".

This function will return a data.frame object containing the predicted AUC matrix.

3. Query gene of interest.

cor_mat <- iLICOB_query(input.gene = "CD274", input.omics = "RNA", cor.method = "pearson")

input.gene is an official gene symbol.

input.omics is the omics type of input matrix. It supports "RNA", "Protein", "CNV", and "Methylation". The default value is "RNA".

cor.method is the correlation type. It supports "pearson" and "spearman". The default value is "pearson".

This function will return a data.frame object containing the correlation estimate and P value between omics profile and drug response.
