| dataentry {base} | R Documentation |
This is a suite of functions designed to make the interface to the spreadsheet painless for users.
data.entry(..., Modes = NULL, Names = NULL) dataentry(data, modes) de(..., Modes = NULL, Names = NULL)
data.entry has side
effects, any changes made in the spreadsheet are reflected in the
variables. The functions de, de.ncols, de.setup
and de.restore are designed to help achieve these side effects.
If the user passes in a matrix, X say, then the matrix is
broken into columns before dataentry is called. Then on return
the columns are collected and glued back together and the result
assigned to the variable X. If you don't want this behaviour
use dataentry directly.
The primitive function is dataentry. It takes a list of
vectors of possibly different lengths and modes (the second argument)
and opens a spreadsheet with these variables being the columns.
The columns of the dataentry window are returned as vectors in a
list when the spreadsheet is closed.
de.ncols counts the number of columns which are supplied as arguments
to data.entry. It attempts to count columns in lists, matrices
and vectors. de.setup sets things up so that on return the
columns can be regrouped and reassigned to the correct name. This
is handled by de.restore.
