Dear group, I know this issue has been already covered, and before you reply I must say I have read the R-FAQ and search the mailing list archive. I still can't manage to change my factor to numeric as I couldn't find any clear answer.

Update: Grand Prix 4 plays almost flawlessly with Catalyst 10.6 and WINE 1.2rc3.. HOWEVER, over the past few releases of WINE (audio work), I've noticed that partly through the playback of Grand Prix 4, the audio suddenly stops. Prior to 1.2rc3, Grand Prix 4 used to crash shortly thereafter. However, since WINE 1.2rc3, after the audio stops, Grand Prix 4 continues without crashing ... just

hi! i'm quite new in R and i don't understand why this statement doesn't work: > mode(mensuel$VARIANCE.PRIX) [1] "numeric" > storage.mode(mensuel$VARIANCE.PRIX) [1] "integer" > mean(mensuel$VARIANCE.PRIX) [1] NA Warning message: argument is not numeric or logical: returning NA in: mean.default(mensuel$VARIANCE.PRIX) Thanks for help!

Full_Name: Johannes Prix Version: 2.1.1 OS: WinXP, SuSE Linux Submission from: (NULL) (137.208.41.195) The seq-command produces unnescessary inaccurate results, which can be extremely annoying. I absolutely do not see the nescessity of numerical garbage to appear in the following simple case. E.g. try this: > seq ( 61.55 , 62.00 , by=0.01 ) - round ( seq ( 61.55 , 62.00 , by=0.01 ) ,

Grand Prix 4 doesn't install completely, i.e. the installation terminates just at the end of the process which might be due to the msi installer. Links 2003 installs, but aborts in the early stages of boot which might be due to copy protection, e.g. SafeDisc.

wine dxdiag.exe spews a few fixme messages (Related to ALSA drivers) and then exits. No Window, no error messages. Till now, this wasn't a problem (several games ran fine) but when I tried installing a legacy game (Grand Prix World by Microprose), it could not detect my graphics card. Tried DxDiag but it isnt working. Any help will be much appreciated, thanks.
