This is not a homework assistance forum. You really need to use the resources
provided by your educational institution for that. Please read the Posting
Guide, and note for future reference that HTML email distorts your R code so it
is not appropriate on this list.
As regards your question, you may need to review the Introduction to R document
that comes with R. Then you might as well get started learning how to use the
help system, paying close attention to the first argument and (return) value
for the rainbow function.
?rainbow
?"["
Also, the str function can help you decipher bits of code:
str(rainbow)
str(rainbow(50))
str(rainbow (50)[46])
