| bhist {mining} | R Documentation |
Same as hist except a confidence interval is drawn
around each bin height.
bhist(x,b=NULL,z=1)
x |
a numerical vector |
b |
the number of bins, or a vector of break locations. If NULL, chosen automatically by hist. |
The width of the interval for height p is sqrt(p*(1-p)/n)*exp(-1/6/p/n).
None.
