[R] Error in saveLog(currentLogFileName

[David Winsemius]

This is just two suggestions and a guess.

a) When you desire the information from sessionInfo ,you need to type :
sessionInfo()   # not sessionInfo

... results come from function calls and all you got was the  
sessionInfo code produced by the implicit print function to which you  
gave the argument sessionInfo.

b) Tell us exactly the methods you used to save "my script", "my  
workspace", "etc"?

c) As a guess, you had the Zelig package loaded under R-Commander  
yesterday but not today. The right person to ask this question of  
might be one of those package maintainers. (John Fox is very good  
about supporting R-Commander.)
