MetaR Languages

The goal of the MetaR project is to provide a tool for educating biomedical researchers in data analysis by keeping the learning curve as smooth and simple as possible.

Description

Omitting non-essential elements is especially important when the user is a computational beginner. For this reason, MetaR was created to keep the focus on the data analysis rather than the technical details.

MetaR takes advantage of Language Workbench Technology to facilitate data analysis with the R language. The tool is tailored for biologists with no programming experience, as well as expert bioinformaticians and statisticians. MetaR is not a replacement for R, it is a tool built on top of R.

Where MetaR can help

MetaR performs statistical analyses over RNA-Seq data.

A typical MetaR analysis starts from a read count matrix, where each column is a sample and each row is a gene.

Major features of MetaR include:

• data abstraction
• data manipulation
• data analysis
• graphical visualization of the results
• integration with virtual environments (for enhanced reproducibility)
• versioning of your projects
