concatenation.R

# Set up some test data
my_names <- letters[1:5]
my_names
# [1] "a" "b" "c" "d" "e"

# We want a list, like "a, b, c, d, e"

# Paste the names together
paste(my_names)
# [1] "a" "b" "c" "d" "e"
# Not the result we were looking for

# paste() with the collapse= parameter produces the desired result
paste(my_names, collapse = "")
# [1] "abcde"

paste(my_names, collapse = ", ")
# [1] "a, b, c, d, e"
