coralPval {DAAG}

P-values from biological expression array data

Description

P-values were calculated for each of 3072 genes, for data that compared expression values between post-settlement coral larvae and pre-settlement coral larvae.

Usage

data("coralPval")

Format

The format is: num [1:3072, 1] 8.60e-01 3.35e-08 3.96e-01 2.79e-01 6.36e-01 ...

Details

t-statistics, and hence p-values, were derived from five replicate two-colour micro-array slides. Details are in a vignette that accompanies the DAAGbio package.

Examples

## From p-values, calculate Benjamini-Hochberg false discrimination rates
fdr <- p.adjust(DAAG::coralPval, method='BH')
## Number of genes identified as differentially expressed for FDR = 0.01
sum(fdr<=0.01)
