histdata | R Documentation |
Returns data for a histogram. Calls internally hist(..., plot=FALSE)
.
mean
returns the mean of the data.
quantile
and median
return the quantile(s) or median with an attribute pos
, the class number of the quantile(s), or the median.

further parameters used in graphics::hist |
Like in graphics::hist, but with this additional list of elements:
lower
lower class borders,
upper
upper class borders,
width
class widths,
relfreq
the relative class frequency,
cumfbrk
the cumulated relative frequency of the breaks
,
maxdens
the indices of the maximal density
values,
maxcount
the indices of the maximal count
values
x
the original finite data, and
class
the class number for each value in x
.
#1
x <- seq(0, 1, by=0.25)
print(hist(x, plot=FALSE))
histdata(x)
#2
x <- seq(0, 1, by=0.25)
print(hist(x, x, plot=FALSE))
histdata(x, x)
#3
print(hist(x, x, right=FALSE, plot=FALSE))
histdata(x, x, right=FALSE)
