[R] How to assign value to a variable dynamically constructed

[Jun Shen]

Dear list,

Let's say we have a variable (id), whose name is dynamically constructed.
This variable represents a vector or data frame with many elements. Now I
want to specifically assign a value to one of the elements. I couldn't get
it right.

test <- 'id' # "id" is dynamically constructed through paste()

id <- 1:4

# I can get the element by doing

get(test)[2]

# Now I want to assign a value to the second element of this dynamical
variable.

get(test)[2] <- 5  # doesn't work.

Thanks a lot.
