Hi all
I am having troubles making sense of why code (1) below fails but code (2) below works.
Code (1):
> phi.1 <- 1
> plot(0 ~ 0,
+ main=substitute(paste("A vaue for ",phi," = ",phival), list(phival=phi.1)) )
Error in paste("The two deviances for ", phi, " = ", 2) :
Object "phi" not foundBut this works:
Code (2):
> plot(0,0,
+ main=substitute(paste("A value for ",phi," = ",phival), list(phival=phi.1)) )
>
It appears that if the plot command takes the formula style entry, the substitue/paste fails.
Is this documented as a feature (I couldn't find it if that is the case), or is it a bug? If it is a feature, it is a subtle difference between (1) and (2) that has potential to be quite frustrating!
Perhaps I should just upgrade to version 2.0.0, though I can't see anything in the Release Notes that might cause this.
Thanks.
