Description

Steps to reproduce on Windows:
- switch to R perspective
- create a new session
- type or paste these 2 lines in the .R file :

plot(1:10,1:10,type="n")
text(5,5,"test")

- click on "Execute Script"
- evaluation fails with message:

  • Evaluation Error: eval failed, request status: R parser: syntax error : plot(1:10,1:10,type="n")
    text(5,5,"trtrtr")

[At many places in source code we can found "\n", we may use "System.getProperty("line.separator")" which returns the right carriage return and line feed according to the runtime platform. This bug may be related to this "\n" usage]

fixed, but scripts but now explicitly call "print()" to show messages in the RConsole

#3 Updated by Matthieu Decorde over 6 years ago

Les listes R ne s'affichaient pas bien dans la console R. J'ai donc branché directement le flux stdout de Rserve dans la console R

Test OK. Multi-line code is well executed on Win 7 and list viewing works.
NOTE: effectively, we need to use print(), using only a variable name does nothing.
