fromJSON Error in GetSegments()

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Following the Example-Code for Version 1.4
2. Making every step work until ga.segments
3. ga.segments <- conf$GetSegments()

What is the expected output? What do you see instead?

Error en fromJSON(api.response.json, method = "C") : 
  unexpected escaped character '\.' at pos 21

What version of the product are you using? On what operating system?

Version 1.4 and Windows 7 on R 3.0.1

Please provide any additional information below.

Same exact scenario for me, following the ReadMe example code and all. 

My error message is slightly different: 

Error in fromJSON(api.response.json, method = "C") : 
  unexpected escaped character '\s' at pos 15

Version 1.4 (installed into RStudio 0.98.490 with R x64 3.0.2 installed) on a 
Windows 7 64 bit

Given the error message, I even went through my GA account and renamed all of 
my segments, replacing any possibly-sensitive characters (spaces, ampersands, 
etc.) with dashes, hoping that would fix the issue, but that did not fix the 
problem.

It looks like it has to do with the encoding of segments that use regex.  

I have a custom segment that is defined as this: 
ga:hostname=~^m\.

It is encoded on 
https://www.googleapis.com/analytics/v3/management/segments?access_token=... 
like this: 
ga:hostname=~^m\\.

I don't know how to fix it.

Here's a fix that appears to be working for me.
From the R Console:
fix(fromJSON)
Change the first line to this: 
function (json_str, file, method = "C", unexpected.escape = "keep")

The original error was caused by having unexpected.escape = "error"  I think 
the error stems from how R handles/interprets backslashes in Windows.  

Cheers!

Assign a segment for your query like this: 
segment <- ga.segments$segmentId[22]
