predict: apply a trained method to new data, does not work
with all methods, will give an error if there is no apply.
In some cases the apply function may only be an approximation.
inverse: inverse transformation of embedded data, does not
work with all methods, will give an error if there is no inverse.
In some cases the apply function may only be an approximation.
as.data.frame: convert to data.frame
getPars: Get the parameters with which the method
was called.
getNDim: Get the number of embedding dimensions.
print: Method for printing.
getOrgData: Get the original data and meta.data
getDimRedData: Get the embedded data
ndims: Extract the number of embedding dimensions.
getOtherData: Get other data produced by the method
dataOutput data of class dimRedData.
org.dataoriginal data, a matrix.
applya function to apply the method to out-of-sampledata, may not exist.
inversea function to calculate the original coordinates from reduced space, may not exist.
has.org.datalogical, if the original data is included in the object.
has.applylogical, if a forward method is exists.
has.inverselogical if an inverse method exists.
methodsaves the method used.
parssaves the parameters used.
other.dataother data produced by the method, e.g. a distance matrix.
## Create object by embedding data
iris.pca <- embed(loadDataSet("Iris"), "PCA")
## Convert the result to a data.frame
head(as(iris.pca, "data.frame"))
head(as.data.frame(iris.pca))
## There are no nameclashes to avoid here:
head(as.data.frame(iris.pca,
org.data.prefix = "",
meta.prefix = "",
data.prefix = ""))
## Print it more or less nicely:
print(iris.pca)
## Get the embedded data as a dimRedData object:
getDimRedData(iris.pca)
## Get the original data including meta information:
getOrgData(iris.pca)
## Get the number of variables:
