Estimation of local false discovery rates
1 2 |
dataf |
input data file with two columns (1 = gene name, 2= ordered raw pvalues). |
graph |
if TRUE a pdf graphic is created. |
method |
method for estimating m0. This must be one of the strings "adaptive", "conservative", "bootstap", "smoother" or NULL. |
lambda0 |
value used in calculating m0. |
smoothing |
"1" for the initial published method, "2" for the PAVA method isotonic (monotonely increasing nonparametric) least squares regression - see P. Broberg (2005). |
thres |
threshold defining intervals used for the movering average smoothing. |
mm |
parameter defining intervals used for the movering average smoothing. |
- if graph = TRUE, a file of graphics named LocalFDRGraph.pdf
- A data file (LocalFDRFile.txt) with 4 columns : gene name, raw pvalues and two columns corresponding to smoothed FDR values.
