functions: | string->cell csv->spreadsheet row-count row-at sheet sum-row |
string->cell
(define (string->cell s) (error 'not-yet-implemented))
- if s is the empty string, evaluate to void
- if s represents a number, evaluate to that number
- if s starts with "(" and ends with ")", evaluate to a form suited for eval
- otherwise, evaluate to s

(define (csv->spreadsheet matrix) (error 'not-yet-implemented))
row-count
(define (row-count sheet) (error 'not-yet-implemented))
row-at
(define (row-at sheet row-index) (error 'not-yet-implemented))
sum-row
(define (sum-row sheet row-index) (error 'not-yet-implemented))
