kandi X-RAY | MetaboAnalystR Summary
MetaboAnalystR 3.0 contains the R functions and libraries underlying the popular MetaboAnalyst web server, including metabolomic data analysis, visualization, and functional interpretation. The package is synchronized with the MetaboAnalyst web server. After installing and loading the package, users will be able to reproduce the same results from their local computers using the corresponding R command history downloaded from MetaboAnalyst web site, thereby achieving maximum flexibility and reproducibility. The version 3.0 aims to improve the current global metabolomics workflow by implementing a fast parameter optimization algorithm for peak picking, and automated identification of the most suitable method for batch effect correction from 12 well-established approaches. In addition, more support for functional interpretation directly from m/z peaks via mummichog2 (PMID: 23861661), and a new pathway-based method to integrate multi'omics data has been added. To demonstrate this new functionality, we provide the "MetaboAnalystR 3.0 Workflow: Towards an Optimized Workflow for Global Metabolomics" vignette, available here as a PDF. In this vignette, we perform end-to-end metabolomics data analysis on the full batch of clinical IBD samples.

When I get to this stage
...ANSWER
Answered 2020-Jun-01 at 23:03After spending at least 30 minutes installing dependencies from CRAN and Bioconductor, I was able to get the code to work.
If I had to guess your issue, you probably haven't installed all the dependency packages.

Install MetaboAnalystR
MetaboAnalystR 3.0 is freely available from GitHub. The package documentation, including the vignettes for each module and user manual is available within the downloaded R package file. You can install the MetaboAnalylstR 3.0 via any of the three options: A) using the R package devtools, B) cloning the github, C) manually downloading the .tar.gz file. Note that the MetaboAnalystR 3.0 github will have the most up-to-date version of the package. Due to issues with Latex, some users may find that they are only able to install MetaboAnalystR 3.0 without any documentation (i.e. vignettes). The * must be replaced by what is actually downloaded and built.
