Multiplot function

Plot multiple ggplots objects in one panel

ggplot objects can be passed in ..., or to plotlist (as a list of ggplot objects)

For example, if the layout is specified as the matrix(c(1,2,3,3), nrow=2, byrow=TRUE), then plot 1 will go in the upper left, 2 will go in the upper right, and 3 will go all the way across the bottom.

Multiplot(..., Plotlist=NULL, ColNo=1, LayoutMat,Plotter =
                    "native")

Arguments

• ...: multiple ggplot objects to be plotted
• Plotlist: Optional: list filled with ggplot objects to be plotted
• ColNo: Number of columns in layout
• LayoutMat: A matrix specifying the layout. If present, 'ColNo' is ignored.
• Plotter: Optional, either "ggplot", or "native"

Returns

List with Plotlist

Examples

data(Lsun3D)
Data=Lsun3D$Data
Cls=Lsun3D$Cls
obj1=Classplot(Data[,1],Data[,2],Cls=Cls,Plotter="ggplot",Size=3,main="Top plot")
obj2=Classplot(Data[,2],Data[,3],Cls=Cls,Plotter="ggplot",Size=3,main="Middle plot")
obj3=Classplot(Data[,1],Data[,3],Cls=Cls,Plotter="ggplot",Size=3,main="Bottom plot")
V=Multiplot(obj1,obj2,obj3)
