I have just finished installing R 3.1.0, Eclipse Luna, STATeT 3.4 (with RJ 2.0).
I have followed the worksheet, during which I configured an R environment and ran an R console.
I have tried testing all this with Eclipse. When I make a R-Script-File, with a bit of simple code in it such as: x <- 1, it runs fine if I select the line and I click on "Run selection in R".
If I click on the green arrow ("Run"), and then "Run script in R submitting directly", everything works fine.
However, when I click on the green arrow ("Run") and then "Run script in R via source", I get:
An error occured. Connection to R engine is closed.
I also get the message: An error occurred when preparing element tagging for file '/Test Coursera/Test1.R'.
Why does that happen?
Additionally, if I try clicking on "Run File in R via Command", I get the same error, plus this message:
Communication error detail. Send: null
And there are tons on lines under the "Exception Stack Trace" line, the first ones being:
java.rmi.UnmarshalException: Error unmarshaling return header; nested exception is:
java.net.SocketException: Connection reset
On a side note, I don't get at all what I should pick as my "working directory". In R, when I type "getwd()", I get "C:/Users/charl_000/Documents", so that's what I kept in Eclipse. But shouldn't I pick the same folder as my Eclipse workspace? What is the difference between the two?
Thanks in advance!
