Hi,
The ggplot2 includes the very convenient stat_summary function to summarize
y variable data and plot this summary statistic in a y vs x graph. I need
to implement similar functionality in a lattice-based framework.

If I may ask, how can I know the path to the font file(s) used by R when it
generates the png files with the Helvetica font?

Hi David,
Thank you for your response.
I use png devices to create my plots. Looking at ?pdfFonts and ?Type1Font,
I believe these fonts only apply to pdf devices. Additionally, ?grid::gpar

Any suggestions?

The warnings section in ?png indicate that Helvetica is the default font.
Now I need to verify if this is true for my plot and find out where this

Dear R-users,
I would like to know if there is a function (in base R or the extension
packages) that would automatically detect the break points in a vector x
for later use in the cut function. The idea is to determine the boundaries
of the n intervals (n=1) delimiting clusters of data points
Obviously, cut would do the job if one knows the number of intervals in
advance, which I assume I won't. I guess what I'm looking for is a function
that figures out the number of intervals and their boundaries.
