"WebbThe definition of histogram differs by source (with country-specific biases). R 's default with equi-spaced breaks (also the default) is to plot the counts in the cells defined by breaks. Thus the height of a rectangle is proportional to the number of points falling into the cell, as is the area provided the breaks are equally-spaced. " - Hist density r
