Hi there fellow R-users,
I'm stuck on this seemingly trivial problem.
All I want to coerce a character string into a command.
For example:
x<-rnorm(20) y<-rnorm(20) str<-"lm(y~x)"
I want to evaluate the "str" command.
I have tried
eval(as.expression(str))
But it doesn't seem to work. I am aware of the call command, but for
reasons I won't go into I would prefer not to use it.
Any help would be great.
Regards, Wayne
