Normalizing data
Hello,
I have a data set of about 300.000 measurements made by an STM which should
apporximately fix a normal (Gaussian) distribution.
I have imported the data in R and used plot(density()) to get a nice plot of
the distribution which in fact looks like a real Gaussian.
However, the integral over the surface is not equal to one (I know since
some of the plots extend to numbers greater then 1). Is

fitting a line to a logaritmic plot
Hi,
I have processed measurements of a rough surface to a heigh-height
correlation plot. What the meaning of this exactly is, is not important.
Only that it is a plot that had two (almost ) linear parts when plotted on a
logaritmic scale. In this plot, I want to draw the best fitting lines for
these linear parts but I just can't get it done. It is easy when the scales
are linear but as you
