rowcorMatVec_Bygroup: the grouped version for rowcorMatVec

In nickytong/GenAnalysis: Genomic Analysis

Description

This calculated the correlation between rows of mat and vec but at each group at a time as specified by the group vector It should be more flexible than rowcorMatMat which requires the same genomic mat; instead, here different group of analysis can have different sample size in genomics

Usage

rowcorMatVec_Bygroup(mat, vec, group, addAll = FALSE, addAllName = "all",
  parallel = FALSE, core = 1, method = "spearman", minN = 5,
  usercorr = TRUE, returnArray = TRUE, symbol = NULL,
  sepSymProbe = ", ", ...)

Arguments

mat	a matrix, i.e. gene expression
vec	a vector of phenotype, continuous variable
group	a vector, categorical variable
addAll	whether to calculate correlation by using all data ignoring group; this is the overall correlation
parallel	deprecated; parallel is automatically enabled when core>1
core	number of cores to use; when core>1, parallel execution is enabled
...	additional parameters to rowcorMatVec
addData	logical indicating if data (mat) should be attached as an attribute (may be used for scatter plot)

Value

a 3D array
