# [M]()ulti-region [e]()xome [s]()equencing analysis tool [Kit]() Intra-tumor heterogeneity (ITH) is now thought to be a key factor contributing to the therapeutic failures and drug resistance, which have attracted increasing attention in the cancer research field. Here, we present an R package, MesKit, for characterizing cancer genomic ITH and inferring the history of tumor evolution via implementation of well-established computational and statistical methods. The source code and documents are freely available through Github (https://github.com/Niinleslie/MesKit). A shiny application was developed to provide easier analysis and visualization. ## Installation ```R # install via Bioconductor if (!requireNamespace("BiocManager", quietly = TRUE)) install.packages("BiocManager") BiocManager::install("MesKit") # install the latest version from GitHub if(!require(devtools)) install.packages("devtools") devtools::install_github("Niinleslie/MesKit") ``` ## Usage The structured documentation of MesKit can be found at [http://meskit.renlab.org/\](http://meskit.renlab.org/).
