Recycling can be used in a clever way to simplify code. Subsetting If we want to keep every third element of a vector we can do the following: my_vec <- c(1,2,3,4,5,6,7,8,9,10) my_vec[c(TRUE, FALSE)] [1] 1 3 5 7 9 Here the logical expression was expanded to the length of the vector. ...

The simplest way to refer to a single cell on the current Excel worksheet is simply to enclose the A1 form of its reference in square brackets: [a3] = "Hello!" Note that square brackets are just convenient syntactic sugar for the Evaluate method of the Application object, so technicall...

The pattern (p1, p2) is strict in the outermost tuple constructor, which can lead to unexpected strictness behaviour. For example, the following expression diverges (using Data.Function.fix): fix $ \(x, y) -> (1, 2) since the match on (x, y) is strict in the tuple constructor. However, the fo...

It is the basic usage of the TextInputLayout. Make sure to add the dependency in the build.gradle file as described in the remarks section. Example: <android.support.design.widget.TextInputLayout android:layout_width="match_parent" android:layout_height="wra...
