comp.F {DEDS} | R Documentation |
comp.F
returns a function of one argument with bindings for
L
. This function accepts a microarray data matrix as its single
argment, when evaluated, computes F statistics for each row of the
matrix.
comp.F(L = NULL)
L |
A vector of integers corresponding to observation (column) class labels. For k classes, the labels must be integers between 0 and k-1. |
comp.F
returns a function with bindings for L
,
which calculates and returns of vector of F statistics for
each row in the data matrix.
