  Discovering patterns of the complex high-dimensional data is a long-standing
problem. Dimension Reduction (DR) and Intrinsic Dimension Estimation (IDE) are
two fundamental thematic programs that facilitate geometric understanding of
the data. We present Rdimtools - an R package that supports 133 DR and 17 IDE
algorithms whose extent makes multifaceted scrutiny of the data in one place
easier. Rdimtools is distributed under the MIT license and is accessible from
CRAN, GitHub, and its package website, all of which deliver instruction for
installation, self-contained examples, and API documentation.
