Reduces the dimensionality of a data set.
project(x,w)
x |
a data frame |
w |
a matrix with named rows and columns |
Each column of w specifies a new variable, which is to be
constructed by combining existing variables according to the given weights.
A data frame where the variables named in the rows of w are
replaced by new variables named in the columns of w.
Other variables are left unchanged.

data(iris) w = projection(iris,k=2) # w only involves the continuous attributes # the new variables are h1 and h2 x = project(iris,w) color.plot(x) plot.axes(w)
