The mixtures of tables and graphics we've produced are a bit different
from the examples you gave but demonstrate the value of combining R and
LaTeX. R can produce LaTeX code containing LaTeX picture environments,
for example. That's how we put tiny high-resolution histograms inside
tabular output showing descriptive statistics in the describe function
and its latex method latex.describe in the Hmisc package. Charles
Thomas Dupont is working on a more impressive graphic inside a table by
adding tiny dot charts showing proportions and confidence limits for
differences in probabilities to the output produced by the latex method
for Hmisc's summary.formula function.
An example of the first type may be found in
http://biostat.mc.vanderbilt.edu/StatGraphCourse under "Mixing Text and
Graphics" and we'll add an example of the second type soon.
LaTeX offers another approach: tables (matrices) of graphics in the
tabular environment.
