converting JSON object in R to string representation gives \" rather than ". How to get rid of slash?
<p>I need to get ride of the forward slash when converting a JSON object to a string. Why do I get \" rather than the double quote, and how can I show as just a double quote with the slash? Consider the example, d_json without slash, but slash appears when converted to string:</p>

<pre><code>library(jsonlite)
d = data.frame(one=as.factor(c('a','a','b','b','c','c')),
           two=c(1,2,3,4,5,6))

d_json &lt;- toJSON(d)
d_json
##[{"one":"a","two":1},{"one":"a","two":2},{"one":"b","two":3},{"one":"b","two":4},{"one":"c","two":5},{"one":"c","two":6}] 

toString(d_json)
##[1] "[{\"one\":\"a\",\"two\":1},{\"one\":\"a\",\"two\":2},{\"one\":\"b\",\"two\":3},{\"one\":\"b\",\"two\":4},{\"one\":\"c\",\"two\":5},{\"one\":\"c\",\"two\":6}]"
</code></pre>
