| iter-methods {Biobase} | R Documentation |
This is a set of methods to iterate over different types of
objects. The behaviour of the methods is similar to that of the
apply family.
f to the rows of the expression data, exprs, of
object. f is a list of functions, each of which returns a
single value. The functions are applied sequentially to the rows of the
expression data, exprs, of object. The answers are stored in
the columns of the return matrix. f is assumed to be a function of two arguments. The covariate in
the object with name specified by covlab is extracted and
bound to the second argument of f. Then the resultant function is
passed back through iter and we effectively obtain the result of
this function applied to the rows of the expression data, exprs, of
object.
