data.entry(..., Modes = NULL, Names = NULL)
dataentry(data, modes)
de(..., Modes = list(), Names = NULL)
data
giving the
modes of (some of) the variables. list()
is allowed.de
and dataentry
return the edited value of their
arguments. data.entry
invisibly returns a vector of variable
names but its main value is its side effect of assigning new version
of those variables in the user's workspace.
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
.
