Function for exporting a design object
export.design(design, response.names = NULL,
path = ".", filename = NULL, legend = NULL, type = "html",
OutDec = options("OutDec")$OutDec, replace = FALSE, version = 2, ...)
html(object, ...)
# S3 method for data.frame
html(object, file = paste(first.word(deparse(substitute(object))),
"html", sep = "."), append = FALSE, link = NULL, linkCol = 1, bgs.col = NULL,
OutDec=options("OutDec")$OutDec, linkType = c("href", "name"), ...)The functions are used for their side effects and do not generate a result.
A data frame of class design; it must be stored in the global environment and referred to by its name, i.e. it cannot be created “on the fly”.
if not NULL (default), this must be a character vector of response names; the exported file contains a column for each entry; it is NOT necessary to include responses that are already present in the design object!
the path to the directory where the export files are to be stored;
the default corresponds to the R working directory that can (on some systems)
be looked at using getwd()
character string that gives the file name (without extension) for the files to be exported; if NULL, it is the name of the design object
data frame containing legend information; if NULL,
the legend is automatically generated from the
factor.names element of design.info(design)
one of "rda", "html", "csv", or "all".
An R workspace with just the design object is always stored as an "rda" object.
If one of the other types is specified, the design is additionally exported to "html"
or "csv" or both. The "csv" file contains the design itself only,
with formatting depending on the OutDec option. The "html" file contains
some additional legend information and row color formatting.
decimal separator for the output file; one of "." or ",";
the default is the option setting in the R options; this option also directs
whether write.csv or
write.csv2 is used and is very important for
usability of the exported files e.g. with Excel
logical indicating whether an existing file should be replaced; if FALSE (default), the routine aborts without any action if one of the files to be created exists; checking is not case-sensitive in order to protect users on case-insensitive platforms from inadvertent replacing of files (i.e. you cannot have TEST.html and test.html, even if it were allowed on your platform)
the save version for the rda file; starting with R 3.6.0,
the default save version is 3; that version cannot be read by R versions
before 3.5.0. Therefore, the default of this package is still 2, but can
be overwritten by users who are certain to use the file only on new R versions.

Function export.design always stores an R workspace that contains just
the design (with attached attributes, cf. class design). This file is stored
with ending rda.
If requested by options type="csv", type="html", or type="all",
export.design additionally creates an exported version of
the design that is usable outside of R. This is achieved via functions
write.csv, write.csv2 or html.
The csv-file contains the data frame itself only, the html file contains the data frame
followed by the legend to the right of the data frame. The html file uses row coloring in
order to prevent mistakes in recording of experimental results by mix-ups of rows.
If the OutDec option is correct for the current computer, the csv and html files can
be opened in Excel, and decimal numbers are correctly interpreted.
Generation of the html-file is particularly important for Taguchi inner/outer array designs in wide format, because it provides the legend to the suffix numbers of response columns in terms of outer array experimental setups!
The function html and its data frame method are internal.
