MetaDE.minMCC
Identify differentially expressed genes with the same pattern across studies/datasets.
1 | MetaDE.minMCC(x,nperm=100,miss.tol=0.3)
|
x |
a list of data sets and their labels. The first list is a list of datasets, the second list is a list of their labels. see examples for details. |
nperm |
The number of permutations. If nperm is NULL,the results will be based on asymptotic distribution. |
miss.tol |
The maximum percent missing data allowed in any gene (default 30 percent). |
A list containing:
meta.analysis$meta.stat |
the statistics for the chosen meta analysis method |
meta.analysis$pval |
the p-value for the above statistic. It is calculated from permutation. |
meta.analysis$FDR |
the FDR of the p-value. |
meta.analysis$AW.weight |
The optimal weight assigned to each dataset/study for each gene if the 'AW' or 'AW.OC' method was chosen. |
raw.data |
the raw data of your input. That's x. This part will be used for plotting. |
