Description Usage Arguments Details
The function estimates differences between 2 precision matrixes. Then a multiple testing procedure with false discovery rate control will be applied to determine different entries between 2 matrixes. The testing result will be turned into a binary matrix which can be used as screening matrix for CFGL.

verbose = F)
|
expr1 |
A n*p matrix or data frame of normalized gene expression data. The rows correspond samples (n), the columns correspond genes (p). |
expr2 |
The second gene expression data, should be in the same format, size as expr1. |
s |
The tuning parameter for matrixes differences estimation, leave it as NULL to automatically select. |
s.seq |
The candidates for s selection. |
alpha |
Prespecified level of false discovery rate. A relatively loose criterion is suggested for determines screening matrix. |
verbose |
Set verbose to TURE to show details of s selection. |
