TME infiltration patterns were determined and systematically correlated with TME cell phenotypes, genomic traits, and patient clinicopathological features to establish the TMEscore:Tumor Microenvironment Characterization in Gastric Cancer Identifies Prognostic and Immunotherapeutically Relevant Gene Signatures.
TMEscore is an R package to perform tumor microenvironment analysis. Main advantages: 1. Provides functionality to calculate Tumor microenvironment (TME) score (PCA or z-score) 2. Functions to visualize TME data. 3. Identify TME relevant mutations.
The package is not yet on CRAN. You can install from Github:
# install.packages("devtools")
if (!requireNamespace("TMEscore", quietly = TRUE))
devtools::install_github("DongqiangZeng0808/TMEscore")Main documentation is on the tmescore function in the package:
