PatternHunter: Pattern hunter

In flajole/MApckg: R package of MetaboAnalyst functions

Description

Correlation analysis.

FeatureCorrelation performs analysis against a given feature. Writes an output file "correlation_feature.csv"

Match.Pattern performs analysis against a given pattern. Writes an output file "correlation_pattern.csv" respectively.

Usage

FeatureCorrelation(dataSet, analSet, dist.name = "pearson", varName)

Match.Pattern(dataSet, analSet, dist.name = "pearson", pattern = NULL)

Arguments

dataSet	List, data set object generated by MS_to_MA function.
analSet	List, containing the results of statistical analysis (can be just an empty list).
dist.name	Method of correlation calculating, one of "pearson", "kendall", "spearman"
varName	The name of the feature to perform correlation analysis against.
pattern	A character vector, the pattern to search. The pattern is specified as a series of numbers separated by "-". Each number corresponds to the expected expression pattern in the corresponding group. For example, a 1-2-3-4 pattern is used to search for features that increase linearly with time in a time-series data with four time points (or four groups). The order of the groups is given as the first item in the predefined patterns.

Value

Native analSet with one added $corr element consisting of

• $corr$sig.nm - ???

• $corr$cor.mat - correlation matrix

• $corr$pattern - name of the feature of comparison or the used pattern.
