MAIT.object


P-value threshold. Variables having a p-value lower than this value is considered as a significant variable.


pvalue


Post-hoc method to be used to correct the p-values.


p.adj


Set to TRUE if an output table has to be produced. See function <a rd-options="" href="/link/sigPeaksTable?package=MAIT&version=1.6.0" data-mini-rdoc="MAIT::sigPeaksTable">sigPeaksTable</a> for more information.

Function spectralKruskal takes an <code><a rd-options="" href="/link/MAIT-class?package=MAIT&version=1.6.0" data-mini-rdoc="MAIT::MAIT-class">MAIT-class</a></code> object and obtains which of the variables are significant given a p-value threshold following a Kruskal-Wallis test. The parameters of the significant features can ve printed to an output table (TRUE by default).

The MAIT package contains functions to perform end-to-end
statistical analysis of LC/MS Metabolomic Data. Special
emphasis is put on peak annotation and in modular function
design of the functions.
