cellranger 1.1.0.9000

cellranger 1.1.0

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, readxl, and 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".
