Rebooting to support parsing of spreadsheet formulas and cell references as they appear in unevaluated expressions. This work is still in progress but a CRAN update is required now to update a test for testthat v1.0.x.
Package is beginning to implement classes and methods related to cell location and reference from 'Spreadsheet Implementation Technology' by Peter Sestoft, MIT Press, 2014.
New classes:
* `cell_addr`: one or more absolute cell addresses
* `ra_ref`: single absolute, relative, or mixed cell reference
# cellranger 1.0.0
* The two components of a `cell_limits` object now correspond NOT to row and column limits, but rather to the upper left and lower right cells of the rectangle. See #6. It was too confusing to have different conventions for the object and its print method.
* If the maximum row or column is specified, but the minimum is not, then we automatically set the associated minimum to 1, instead of leaving as `NA`.
* The `header` argument of `anchored()` has been renamed to `col_names`, for greater consistency with [`readr`](https://github.com/hadley/readr), [`readxl`](https://github.com/hadley/readxl), and [`googlesheets`](https://github.com/jennybc/googlesheets/).
* Added a `NULL` method for `as.cell_limits` generic so that `as.cell_limits(NULL)` returns default, degenerate cell limits, i.e. the min and max for rows and columns are uniformly `NA`.
* A `cell_limits` object now inherits from "list".
# cellranger 0.1.0
* Initial CRAN release
