According to the help file, the history() function is supposed to show recent
command history. However, it does not do this in the current Mac OS X version.

Instead, the history function appears to simply show the contents of the file
~/.Rhistory.


I believe you are refering to the R.app console, not R (the 
command-line interface).  In which case this is a problem in R.app, a 
separate project for which you are asked to send reports to the 
R-sig-mac list (see the posting guide under 'Platform-specific 
questions').

Re: [Rd] Possible bug in summary.survfit - 'scale' argument ignored?

2009-04-08 Thread Marc Schwartz

Thomas,

I worked on the plane home last night and have a modified version that  
restores the original behavior vis-s-vis the interaction between the  
'times' and 'scale' arguments, so that 'times' are in the 'scale'  
transformed range.


I am attaching both a patch file and the complete function code. The  
patch is against the current version in R-Forge. If you should try to  
run the full code file to test this, note that survmean() is not  
exported in the survival NAMESPACE, hence if run 'as is' there will be  
an error message about this function not being found.


I would of course advise appropriate review and testing before  
considering committing this.


Regards,

Marc
