error message showed up when initially double-check radiant.bat(marketing)

[to6c]

After I installed the radiant and clicked the radiant.bat(marketing) , the cmd windows showed the message as follows: Listening on http://127.0.0.1:4444 Error in eval(substitute(expr), envir, enclos) : corrupt 'grouped_df', contains 70 rows, and 168 rows in groups Error in eval(substitute(expr), envir, enclos) : corrupt 'grouped_df', contains 70 rows, and 168 rows in groups Error in eval(substitute(expr), envir, enclos) : corrupt 'grouped_df', contains 70 rows, and 168 rows in groups

[vnijs]

Can you provide some more information? What OS? What browser? Does a browser open? If so, what does it show? Did it work before? What version are you using?

[to6c]

windows 10, chrome (opened) , R Studio was also running (Version 0.99.484). R version 3.2.2 (2015-08-14) . Chrome showed the same error message too. But now I double checked the bat file and the browser will not show Radiant. This is first time I installed Radiant in this computer ( I have been using Studio for two months).

[to6c]

I closed the cmd windows and ran the bat file again, now Radiant showed on the browser but with same error.

I have over 300 students running Radiant this quarter but don't think I have seen this issue. Could you try the install instructions (exactly) linked below? Windows 10 can have permission issues with R packages when installed in c:\program files\ and packages in Documents folder. Any initial problems with Windows 10 were resolved by installing R in c:\R\R3.2.2 instead.

Also, can you send a screen shot with ALL message lines from the terminal window? Thanks

I did follow the installation guide on http://vnijs.github.io/radiant/install. Here are ALL the messages lines from the terminal:

Can you try updating to the latest version and removing the C:\Users\jason li\Documents\r_sessions directory? Like I said, I haven't seen this error before and cannot replicate it. Have you tried running Radiant on another computer?

[to6c]

Thank you Professor Vnijs,

I removed C:\Users\jason li\Documents\r_sessions directory and it worked fine now. Thanks.

[vnijs]

Excellent. Thanks for letting me know. It is best to stop Radiant by clicking the 'power' icon and then 'stop'. Otherwise it will try to open a backup next time you start Radiant. To clear out backups click 'power' and then 'refresh', or remove the r_sessions directory.
