ggplot causes error when executed in a knitr chunk (Rstudio)

[Timothy Wyant]

A "compile pdf" in Rstudio of this Rnw:

\documentclass{article}

\begin{document}

Here is the test.

<<Plot_assets>>=

library(ggplot2)

data=data.frame(x=1:5,y=1:5)

ggplot( data, aes(x=x,y=y)) + geom_line()

@

\end{document}

fails with this error:

Quitting from lines 5-9 (Test.knitr.ggplot.Rnw) 

Error in stri_split_regex(string, pattern, n = n, simplify = FALSE, opts_regex = attr(pattern,  : 

  Missing closing bracket on a bracket expression. (U_REGEX_MISSING_CLOSE_BRACKET)

Calls: knit ... <Anonymous> -> str_split -> stri_split_regex -> .Call

If I comment out the ggplot line, compiles fine (with no plot, of course)

If "run all chunks" the R runs fine and produces the plot.

Problem is entirely in the ggplot line.

Have done lots of Rnw documents with ggplot.  This is first time I have had a problem like this.

Rstudio version 0.99.441

Mac OS X version 10.10.5

Works for me on W7 64 bit, knitr_1.10.5.

Cheers,

I'm having the same problem, and it's a new problem as well. Let me know if you find a solution.
