I just figured out that there is the
pgfplots package with the
hist feature, that allows to "draw" histograms based on an external data table.
What I'm looking for is a possibility to transform a histogram into density plot, where instead of counts I have densities according to breaks.
It is like the
hist function in R (if anybody knows) with parameters
freq = FALSE.
Or, is there any other way (package) to plot density from the data set in LaTeX?
