Menu.ExpImp: Exporting and importing Designs
Description
This help file describes facilities for exporting and importing designs.Details
Exporting is often useful, as experimental data are often more easily entered
using software like Excel. For this purpose, it is possible to export an
experimental design as a csv- or html-file.
If the files are handled in a controlled way, response data that are entered
as additional columns to an exported csv- or html-file can be
re-imported later, using the re-import menu accessible from the import menu.
For more detail,
cf. export.design for the exporting and
add.response for the re-importing based on a
csv-file and an rda-file.
Importing a design into R-Commander can either mean selecting it as the active
data set from the R-workspace (with the advantage of being offered designs only)
or importing a previously-exported design, using both an edited csv-file
(created from a stored html- or csv-file) and an rda-file.
It is assumed that the csv file contains new responses, while the
rda-file contains all the structural information on the design.
If an exported rda-file is available (like in the previous paragraph)
but responses are stored in a format different from csv, it is
also possible to re-import the response data into the design. If the design without
responses is the active design (e.g. after loading the rda file using
the Load data menu item from the Data management menu),
the response data can be imported using the appropriate menu item of the
Import data sub menu of the Data management menu. Subsequently,
the response data can be added to the design using the Add response variable(s)...
item of the Modify design ... sub menu of the Design menu.
It is also possible of course to import experimental data generated elsewhere
that do not contain the structural information available with
class design by using the usual import
facilities from the Data management menu of R-Commander.
However, for such experimental data,
the usability of special features of package RcmdrPlugin.DoE
is severely restricted.
