dr: Dimensionality reduction

In ToshihiroIguchi/dr: Dimensionality reduction

Description

Wrappers of various dimension reduction algorithms. Data after dimension reduction can also be easily visualized.

Usage

dr(formula, data, normalize = TRUE, unique = TRUE,
               methods = c("pca", "kpca" ,"mds", "tsne", "lle", "som", "diffmap"),
               kpca.par = list(kernel = "rbfdot", sigma = 0.1),
               mds.par = list(k = 2),
               tsne.par = list(dims = 2, initial_dims = 50, perplexity = 30, theta = 0.5),
               lle.par = list(m = 2, k = 5, reg = 2, p = 0.5),
               som.par = list(xdim = 5, ydim = 6),
               diffmap.par = list(neigen = NULL, t = 0, maxdim = 50, delta=10^-5))

Arguments

formula	an object of class "formula" : a symbolic description of the model whose dimension is reduced. Explanatory variables may be present or absent, and may be factors or numerical values.
data	an optional data frame containing the variables in the model.
