R: 3D plot of points

Plot3D {DataVisualizations} | R Documentation

## 3D plot of points

### Description

A wrapper for Data with systematic clustering colors for either a 2D (x,y) or 3D (x,y,z) plot combined with a classification

### Usage

    Plot3D(Data,Cls,UniqueColors,

    size=2,na.rm=FALSE,Plotter3D="rgl",...)

### Arguments

`Data` | [1:n,1:d] matrix with either `d=2` or `d=3`, if `d>3` only the first 3 dimensions are taken
`Cls` | [1:n] numeric vector of the classification of data with `k` classes
`UniqueColors` | [1:k] character vector of colors, if not given DataVisualizations::DefaultColorSequence is used
`size` | size of points, for plotly additional a vector [1:n] of a mapping of sizes to Cls has to be given in the (...) argument with `sizes=`
`na.rm` | if `na.rm=TRUE`, then missing values are removed
`Plotter3D` | in case of 3 dimensions, choose either "plotly" or "rgl", if one of this packages is not given, the other one is selected as a fallback method
`...` | further arguments to be processed by `plot3d` or `geom_point` or `plot_ly` of type "scatter3d"

### Details

For `geom_point` only `size` and `na.rm` is available as further arguments.

### Note

Uses either `geom_point` for 2D or `plot3d` for 3D or `plot_ly`

    #Spin3D similar output

    data(Lsun3D)
    Plot3D(Lsun3D$Data,Lsun3D$Cls,type='s',radius=0.1,box=FALSE,aspect=TRUE)
    rgl::grid3d(c("x", "y", "z"))

    #Projected Points with Classification
    Data=cbind(runif(500,min=-3,max=3),rnorm(500))

    # Classification
    Cls=ifelse(Data[,1]>0,1,2)
    Plot3D(Data,Cls,UniqueColors = DataVisualizations::DefaultColorSequence[c(1,3)],size=2)

    ## Not run:
    #Points with Non-Overlapping Labels
    #require(ggrepel)
    Data=cbind(runif(30,min=-1,max=1),rnorm(30,0,0.5))
    Names=paste0('VeryLongName',1:30)
    ggobj=Plot3D(Data)
    ggobj +  geom_text_repel(aes(label=Names), size=3)
