A Generic Viewing Function

The function view provides generic interface to the non-generic function View.

In contrast to the implementation of View provided by either basic R or RStudio, this function can be extended to handle new kinds of objects by defining viewPrep methods for them. Further, view can be adapted to other GUIs by specifying the "vfunc" option or the vfunc= optional argument.

Internally, view usues the generic function viewPrep to prepare data so it can be passed on to the (non-generic) function View or (optionally) a different graphical user interface function that can be used to display matrix- or data frame-like objects.

The vfunc argument determines how the result of viewPrep is displayed. Its default is the function View, but an alternative is view_html which creates and displays an HTML grid.

Usage
view(x,
     title=deparse(substitute(x)),
     vfunc=getOption("vfunc","View"),
     …)

# The internal generic, not intended to be used by the end-user. viewPrep(x,title,…) # S3 method for data.set viewPrep(x,title,…) # S3 method for data.frame viewPrep(x,title,…) # S3 method for descriptions viewPrep(x,title,…) # S3 method for codeplan viewPrep(x,title,compact=FALSE,…) # S3 method for importer viewPrep(x,title,compact=TRUE,…)

Arguments
x

an object, e.g. a data frame, data.set, or importer.

title

an optional character string; shown as the title of the display.

vfunc

a character string; a name of a GUI function to call with the results of viewPrep()

compact

a logical value; should the codeplan be shown in a compact form - one line per variable - or in a more expanive form - one line per labelled value?

further arguments; view() passes them on to viewPrep.
