| pValues {StabPerf} | R Documentation |
Computes the p-values for the spots between two sample groups.
pValues(data, labels, one, two, method=wilcox.test)
data |
a data.frame containing samples (columns) and genes (rows) |
labels |
a factor, grouping of the samples |
one |
the name of the first group |
two |
the name of the second group |
method |
some function whose value contains a $p.value field containing p-values. Default:wilcox.test |
Calculates pValues of gene expression between to sample groups. The subsets of data are created using groupData. Then method is used to derive a p-Value for the two expression data-vectors of each spot.
pv |
list of pValues for every spots. |

# calculate the pValues for all spots between "normal" and "early".
p <- pValues(data$x, data$y, 1, 2)
