[Rd] Bug with lists and expressions (PR#589)
Tue, 4 Jul 2000 04:20:04 +0200 (MET DST)
I'm running R 1.1.0 for Windows; the behaviour is the same in 1.0.1.
# create a list containing an expression: no problem
x _ list(NA, expression(1))
# Try to assign an expression to a list element, and get an error:
x[] _ expression(1)
# Try again with a named list element: no problem!
x _ list(a=NA,expression(1))
x$a _ expression(1)
The error message is:
Error in "[[<-"(*tmp*, 1, value = expression(1)) :
I think the error is in "[[<-", but that's a primitive, and I don't
know how to track it down any further.
