charts

A data frame, a matrix-like structure whose columns may be of differing types (numeric, logical, factor and character and so on). How the names Of the data frame are created Is complex, And the rest Of this paragraph Is only the basic story. If the arguments are all named And simple objects (Not lists, matrices Of data frames) Then the argument names give the column names. For an unnamed simple argument, a deparsed version Of the argument Is used As the name (With an enclosing I(...) removed). For a named matrix/list/data frame argument With more than one named column, the names Of the columns are the name Of the argument followed by a dot And the column name inside the argument: If the argument Is unnamed, the argument's column names are used. For a named or unnamed matrix/list/data frame argument that contains a single column, the column name in the result is the column name in the argument. Finally, the names are adjusted to be unique and syntactically valid unless check.names = FALSE.

Violin plot

A violin plot is a compact display of a continuous distribution. It is a blend of boxplot and density: a violin plot is a mirrored density plot displayed in the same way as a boxplot.

A contour plot is a graphical technique for representing a 3-dimensional surface by plotting constant z slices, called contours, on a 2-dimensional format. That is, given a value for z, lines are drawn for connecting the (x,y) coordinates where that z value occurs. The contour plot Is an alternative To a 3-D surface plot.
