Shivaram Venkataraman commented on SPARK-15924:
-----------------------------------------------

I'm not sure what part of this code snippet is specific to SparkR -- The code just looks like ggplot2 / base R functions ?

>             Project: Spark
>          Issue Type: Bug
>          Components: SparkR
>    Affects Versions: 1.6.1
>            Reporter: Xuan Wang

> When I run an R cell with the following comments:
> {code} 
> #   p <- p + scale_fill_manual(values = set2[groups])
> #   # p <- p + scale_fill_brewer(palette = "Set2") + scale_color_brewer(palette = "Set2")
> #   p <- p + scale_x_date(labels = date_format("%m/%d\n%a"))
> #   p
> {code}
> I get the following error message
> {quote}
>   <text>:16:1: unexpected input
> 15: #   p <- p + scale_x_date(labels = date_format("%m/%d
> 16: %a"))
>     ^
> {quote}
> After I remove the backslash in "date_format("%m/%d\n%a"))", it works fine.
