Description Usage Arguments Details Note See Also Examples

This widget needs an widgetObserve to update data set changes to the variable selectors.

1	widgetVariables(env, ...)

`env`	widget: data set widget
`...`	lists: parameter lists for `selectInput` to select one variable

Usually all variables of data frame are offered. If the parameter list for selectInputs contain a parameter vartype=func then only the variables can be selected for which the func delivers TRUE. An example would be vartype=is.factor such that the variable selector just offers the categorical variables of the data frame. The widget must be used together with widgetDataset.

The function will produce a Shiny error if not all data sets read contain at least one appropiate variable.
