Subject: Error Embedding SQL Source from code block into R Source of Another (noweb)
Date: Mon, 29 Sep 2014 19:39:30 -0500	[thread overview]
Message-ID: <87lhp2x7p9.fsf@air.ben-zion.org> (raw)

Dear List:

It is possible to embed SQL code as a string to be evaluated in R. I am
interested in formatting the SQL code in its own source code block, with
its own syntax highlighting and editing mode (C-c ').

The first time I run the code, I am prompted for R starting directory,
but I get an error:

---
load ESSR: + + + Error: unexpected string constant in:
source('~/.emacs.d/elpa/ess-20140913.1153/etc/ESSR/R/.load.R',
local=TRUE) #define load.ESSR
load.ESSR('"
---

and the console locks.  I can C-g to get out of it, and then
re-evaluate, and the code prints what I expect -- the text of the SQL
command.

Is this the right way to go about this?  Have I discovered a bug, or
perhaps accidentally a wrong way to get the right answer?

Is this an ESS problem, and not an orgmode problem, per se?  My ESS
normally starts up fine, so I thought I would ask on this list first.

A minimal example (first failing, second evaluation giving expected
output) follows.

Best regards,

Eric
