Do not worry about those. The key question is how to systematically append/assign these vectors to many objects (hundreds) in a loop without explicitly typing these object names one by one. Please refer to my code posted below to detail my question.  I really appreciate your ideas/suggestions. John

Like David, I find this still somewhat confusing, but perhaps this
will get you started:

a3 <- 1:4
b3 <- 6
c3 <- letters

a_new_thing <- do.call(list, lapply(ls(pattern = "3"), get))

old_thing <- list("cow")

a_longer_old_thing <- c(old_thing, a_new_thing)

adapt as needed.

Best,
Michael
