Dear R-helpers,
I am trying to check whether a model of the form y(t) = a/(1 +b*t) fits the
curve of downloads per day of a file in a specific online community better
than a model of the form y(t) = a*exp(-b*t). For that, I used nls to fit
both models and I am now trying to compare the fits with a

Dear all,
I am plotting a scatter plot for a large sample (1e+05 ordered pairs).
This produces a large (~5MB) file in a pdf or postscript terminal, and
I am wondering whether there are methods for reducing the size of the
resulting file so that it is easier to include it in a document. I'd
rather
#x27;hexbin' for creating the scatter plot.
