npdrDiff | R Documentation |
A diff is a function that computes the difference of values for an attribute between two instances. It is used for attribute selection for attribute diffs and phenotype diffs. This function is vectorized: input a and b can be two vectors of values for one attribute.
npdrDiff(
a,
b,
diff.type = c("manhattan", "numeric-abs", "numeric-sqr", "allele-sharing",
"match-mismatch", "correlation-data"),
norm.fac = 1
)
a |
value of attribute for first instance. Vector for correlation-data. |
b |
value of attribute for second instance. Vector for correlation-data. |
diff.type |
Metric for the difference computation. |
norm.fac |
Normalization factor. |
Value or vector of differences between two vectors element-wise.
