How do I view data in R?
View function invokes a spreadsheet-style data viewer on a matrix-like R object. To view all the contents of a defined object, use the View() function. Behind the scenes, the R returns a view of the object’s contents when it calls utils. This view can then be used to manipulate the data. For example, you can use this view to plot a histogram of values for a given variable.
The following example shows how to create a View object and use it to display the values of two variables. First, we define a variable called x, which represents the value of our first variable, y. Then we create an object called View and assign it a reference to the variable x.
The following code shows the code that creates and displays the view. #include int main(int argc, char *argv[]) { R view; view = new View(1, 1, “x”, 1); view->setValue(x); return 0; } The first line of code creates a new view and sets its value to 1. Then the second line calls the setValue() method of view.
