rrange {sfsmisc} | R Documentation |
Compute a robust range, i.e. the usual range()
as long
as there are no outliers, using the “whisker boundaries” of
boxplot
.
rrange(x, range=1, coef = 1.5, na.rm = TRUE)
x |
numeric vector the robust range of which shall be computed. |
range |
number for S compatibility; |
coef |
numeric multiplication factor definying the outlier boundary, see “Details” below. |
na.rm |
logical indicating how |
The robust range is really just what boxplot.stats(x,
coef=coef)
returns as the whisker boundaries.
This is the most extreme values x[j]
still inside median
plus/minus coef * IQR
.
numeric vector c(m,M)
with m <= M which is (not
strictly) inside range(x) = c(min(x),max(x))
.
