Creating a data table (frame?) from a SQL Statement?
Hello,
I'm new to R so this is probably a simple question for somebody.
I have an RScript that reads a CSV on the disk using read.table(...). It then does a boxM test using that data.
However, I'm now trying to load the same data via an SQL command, but I can't seem to get the data structure defined so R will like it -- using the included "iris" dataset.
I've tried

Please always cc the list... the group usually has better answers than any one person, and I don't do private consulting on the net. For future reference, there is also an r-sig-db mailing list where this question really belongs.
Since I almost never use jdbc, I would need a reprex (hint you are ignoring my advice... a good way to get ignored), which this still isn't. There is probably

How to create a table structure in Java code?
Hi all,
Using RConsole, it's easy to get data from the database that you can use in an R Command. Like this:
(Reference case)
irisQuery <- dbGetQuery(conn, "select * from iris")
boxM(irisQuery [,-5], irisQuery[,5])
----
(Actual case this posting is about)
Yet, if I'm getting that same (sample IRIS) data, say, in a web service possibly POSTED from a SQL command, that same

How to create a table structure in Java code?
That's amazing! Thank you!!!
One follow up question, if that's OK?
If, instead of using hard-coded CSV, I read the CSV into a variable first, then it fails again with a parse error.
Code below.
So, if I read the CSV into a variable, do I need an additional wrapper method?
Seems like it should still work.
Thanks in advance for your reply.

How to create a table structure in Java code?
I suspect that you are looking for something like:
read.csv(textConnection(
"5.1,3.5,1.4,0.2,setosa
4.9,3,1.4,0.2,setosa
4.7,3.2,1.3,0.2,setosa
4.6,3.1,1.5,0.2,setosa
5,3.6,1.4,0.2,setosa"
), header = FALSE)

How to create a table structure in Java code?
You are entering the quoting hell - you are missing quotes and escapes for \n. it would be much more reasonable to use the rConnection.assign method instead of pasting any content through the parser.
Cheers,

How to create a table structure in Java code?
Thanks! I just figured it out (thanks to "Beyond Compare") and was coming here to post back.
The boxM test doesn't work with that (now, finally working) REXP structure, but I probably now need to create a table or something and parse that structure.
So much fun! :)
Thanks again.
