getPvals {singscore} | R Documentation |
With null distributions estimated using the generateNull()
function, p-values are estimated using a one-tailed test. A minimum p-value
of 1/B can be achieved with B permutations.
getPvals(permuteResult, scoredf, subSamples = NULL)
permuteResult |
A matrix, null distributions for each sample generated
using the |
scoredf |
A dataframe, the scored results of samples under test
generated using the |
subSamples |
A vector of sample labels/indices that will be used to subset the score matrix. All samples will be scored if not provided |
Estimated p-values for enrichment of the signature in each sample. A p-value of 1/B indicates that the estimated p-value is less than or equal to 1/B.
