weighted.median {limma} | R Documentation |
Compute a weighted median of a numeric vector.
weighted.median(x, w, na.rm = FALSE)
x |
a numeric vector containing the values whose mean is to be computed. |
w |
a vector of weights the same length as x giving
the weights to use for each element of x . |
na.rm |
a logical value indicating whether NA
values in x should be stripped before the computation proceeds. |
If w
is missing then all elements of x
are
given the same weight.
Missing values in w
are not handled.
The weighted median is the median of the discrete distribution with
values given by x
and probabilities given by w/sum(w)
.
