histogramm?
Hello there! When I do freq=F on hist, I get on the left a small number, what exactly does that mean? Thanks, Martin

...al; if 'TRUE', the histogram graphic is a representation of frequencies, the 'counts' component of the result; if 'FALSE', _relative_ frequencies ("probabilities"), component 'density', are plotted. Defaults to 'TRUE' _iff_ 'breaks' are equidistant (and 'probability' is not specified). Unless I'm missing something, the 'density' component is NOT relative frequency or 'probability' in any reasonable sense, country-specific biases notwithstanding, except in the very specia...

hist function: freq=FALSE for standardised histograms
...histogram graphic is a representation of frequencies, the 'counts' component of the result; if 'FALSE', probability densities, component 'density', are plotted (so that the histogram has a total area of one). Defaults to 'TRUE' _iff_ 'breaks' are equidistant (and 'probability' is not specified). I therefore expect that the following command: > h <- hist(StockReturns, freq=FALSE) where StockReturns has the following data in it: > sourcedata$StockReturns [1] -0.006983 0.111565 0.053782 0...

Strange behavior with "hist" function filled with breaks and freq attribute
...if 'TRUE', the histogram graphic is a representation of frequencies, the 'counts' component of the result; if 'FALSE', _relative_ frequencies ("probabilities"), component 'density', are plotted. Defaults to 'TRUE' _iff_ 'breaks' are equidistant (and 'probability' is not specified). So i'm plotting 3 graphs of probabilities, but because of the breaks the « y » values seems to be broken as if i have to multiplicate the values shown by the break range to have the real percent. So i...
