Distribution of the Sample Median

Compute the distribution sample median of the vector of values given as its argument.

# S3 method for rv
median(x, na.rm = FALSE, ...)

Arguments

x

a randomv vector containing the components whose distribution of the median value is to be computed.

na.rm

a logical value indicating whether NA values should be stripped before the computation proceeds.

...

further arguments passed to median
