Dear R users,
Inspired by previous list discussion of the glob2rxc function, I am
attempting to create a new vector called TOTAL by summing all vectors
whose names begin with ABC:
TOTAL = sum(list = ls(pattern = glob2rx(ABC*)))
I'm running R 2.2.1 on Windows XP. Can anyone say what I'm missing?
Your expression is trying to sum a character vector
containing the names of the variables that begin with ABC.
Try this and try executing each portion of it to understand
it better:
ABC1 - ABC2 - 1
do.call(sum, lapply(apropos(glob2rx(ABC*)), get)) # 2
