rowTtest

Description

performs a two-sided Welch's t-test (unequal variances, equal or unequal sample sizes) on each row of a matrix X with the indices inds.1 vs indices idx2 as group assignments.

Usage

rowTtest(X, idx1, idx2 = -idx1, na.rm = FALSE, alternative = "two.sided")

Arguments

X	Matrix on which the test is performed for every row
idx1	column indices of group 1 members
idx2	column indices of group 2 members
na.rm	Should NAs be removed (logical)
alternative	Testing alternative. Must be one of "two.sided" (default),"less","greater" or "all". in case of "all" a data frome with corresping alternative variables is returned. Otherwise the result is a vector.

Value

vector (or data.frame if alternative=="all") of p-values resulting from the Welch's t-test
