Function showData allows to view data, function fix allows to edit data. For designs, it is only permitted to type in response data and other additional information like date or comments for experimental runs in R, such that all attributes of the design objects are updated accordingly. However, it is recommended to do such editing tasks outside of R, as R is not ideal for these.

For the default function, refer to fix and the links therein.
The function for class design adds the numeric version
(as.numeric) of all newly-entered variables to the
desnum attribute of x and appends the names of all
newly-entered response variables to the
response.names element of the design.info attribute.
If numeric variables are to be entered that are no response variables, the
function should be called with prompt=TRUE so that these are not
taken to be response variables. Automatic default analyses (not yet available) would otherwise
include analyses for these variables.
NOTE: Editing the data in R is only helpful for very small examples, especially when using the default editor under Windows.
NEVER do it to the one and only original data file. It does irrevocably replace it in many cases, even if you realize the mistakes you have made before leaving the editor window.
Function fix is made into an S3 generic. The default method preserves the
functionality from package utils for all objects that are not of class
design.
Function fix immediately commits all changes, overwriting the original object without further notice.
This is also true for the method applicable to objects of class design, as long as
the changes do not destroy the properties of the design.
It is therefore wise to keep a copy of the original,
until correctness of the changes is ascertained.
For design objects, changes are only committed, if no forbidden editing has been done: Changes in values of the experimental factors are not allowed and prevent storing edited information (only reported after the fact, user has no choice in the matter). If the editing would destroy the structure of the design, e.g. because something was typed into an empty row of the data editor which leads to an extra row with missing values, a prompt allows to abort the changes; if changes are committed, the data frame is stored under its original name without any of its attributes (and can thus no longer be treated by any special tools for design objects).
The default method for showData is the function from package relimp,
which is also used in R-Commander for viewing data sets. The method for class design objects
is needed for successfully using the view button of design dataframes in R-commander.
They are undesigned before viewing. However, it is preferrable to inspect a printout from function
print.design which provides additional information.
This can also be done in the R-Commander using the Design menu in package RcmdrPlugin.DoE
(to be available soon).
