R: plot_R_NX

plot_R_NX {dimRed} | R Documentation

## plot_R_NX

### Description

Plot the R_NX curve for different embeddings. Takes a list of `dimRedResult` objects as input. Also the Area under the curve values are computed for logarithmic K (AUC_lnK) and appear in the legend.

### Usage

    plot_R_NX(x)

### Arguments

`x` | a list of `dimRedResult` objects. The names of the list will appear in the legend with the AUC_lnK value.

### Value

A ggplot object, the design can be changed by appending `theme(...)`

### Examples

    ## define which methods to apply
    embed_methods <- c("Isomap", "PCA")
    ## load test data set
    data_set <- loadDataSet("3D S Curve", n = 1000)
    ## apply dimensionality reduction
    data_emb <- lapply(embed_methods, function(x) embed(data_set, x))
    names(data_emb) <- embed_methods
    ## plot the R_NX curves:
    plot_R_NX(data_emb) +
        ggplot2::theme(legend.title = ggplot2::element_blank(),
                       legend.position = c(0.5, 0.1),
                       legend.justification = c(0.5, 0.1))
