I have prepared a Rtex document for processing by knitr. Is it possible to have the LaTeX output from knitr single spaced while the remainder of the LaTeX document is double spaced? If so, what are the chunk options in knitr?

Try adding fig_caption: yes to the YAML header of your .Rmd file. It will look something like this:
---
title: "Untitled"
author: "Nicholas"
date: "20/09/2014"
output:
pdf_document:
fig_caption: yes
---

With a review of the knitr options in the documentation http://yihui.name/knitr/options/ the figures can be resized keeping the aspect ration and they can be rotated plus other options.
\documentclass[10pt,letterpaper]{article}
\usepackage{graphicx}
\begin{document}
Build figure in R and display in default size
<<out.width='4in'>>=
x=rnorm(50)
qqnorm(x)
qqline(x)
@
Now 1/2 size
<<out.width='2in'>>=
qqnorm(x)
qqline(x)
@
Now 1/4 size
<<out.width='1in'>>=
qqnorm(x)
qqline(x)
@
Now rotated at 1/2 size
<<out.width='2in',out.extra='angle=45'>>=
qqnorm(x)
qqline(x)
@
Back to the original
<<out.width='4in'>>=
x=rnorm(50)
qqnorm(x)
qqline(x)
@
\end{document}
Note that each graphic is resized individually.

I figured out a solution by recognizing that knitr creates a new LaTeX environment, knitrout. Therefore, you can specify single spacing within that environment by placing the following statements in the preamble of the Rtex file:
\usepackage{etoolbox}
\AtBeginEnvironment{knitrout}{\singlespacing}
