What is ChemoSpec?

ChemoSpec is collection of functions for plotting spectra (NMR, IR, Raman) and carrying out various forms of top-down exploratory data analysis, such as HCA, PCA, model-based clustering and STOCSY analysis. Robust methods appropriate for this type of high-dimensional data are available. Designed with metabolomics data sets in mind, where the samples fall into groups such as treatment and control. Graphical output is formatted consistently for publication quality plots. ChemoSpec is intended to be very user friendly and help you get usable results quickly. A vignette illustrating typical operations is available.

How to install ChemoSpec

To install from Github using R:

install.packages("devtools")
library("devtools")
install_github(repo = "bryanhanson/ChemoSpec@master")
library("ChemoSpec")

If you use @some_other_branch you can get other branches that might be available. They may or may not pass CRAN checks and thus may not install automatically using the method above. Check the NEWS file to see what's up.

From CRAN using R:

chooseCRANmirror() # choose a CRAN mirror
install.packages("ChemoSpec")
library("ChemoSpec")
