spearman.dist {bioDist} | R Documentation |
Calculate pairwise Spearman correlational distances, i.e. 1-SPEAR or
1-|SPEAR|, for all rows of a matrix and return a dist
object.
spearman.dist(x, ...)
x |
n by p matrix or ExpressionSet; if x is an ExpressionSet, the function uses its 'exprs' slot |
... |
arguments passed to spearman.dist :
TRUE , then 1-|SPEAR| else 1-SPEAR, default is TRUE TRUE , diagonal of the distance matrix will be displayed, default is FALSE TRUE , upper triangle of the distance matrix will
be displayed, default is FALSE |
We call cor
with the appropriate arguments to compute the row-wise
correlations.
One minus the Spearman correlation, between rows of x
, are returned, as
an instance of the dist
class.
