Multivariate independent comparison of observations.
The micompr R package implements a procedure for comparing multivariate
samples associated with different groups. The procedure uses principal component
analysis to convert multivariate observations into a set of linearly
uncorrelated statistical measures, which are then compared using a number of
statistical methods. This technique is independent of the distributional
properties of samples and automatically selects features that best explain their
differences, avoiding manual selection of specific points or summary statistics.
The procedure is appropriate for comparing samples of time series, images,
spectrometric measures or similar multivariate observations.
Install the development version from GitHub with the following command (requires
the devtools package):
devtools::install_github("nunofachada/micompr")
A stable version of the package is available on CRAN and can be installed with
the following instruction:
install.packages("micompr")
All methods and functions are fully documented and can be queried using the
built-in help system. After installation, to access the man pages, invoke the
micompr help page as follows:
help("micompr")
Additionally, the package contains two vignettes with a number of examples.
