x 
the nxp training data matrix. Could be a matrix or a sparse matrix object. 
y 
a response vector for prediction tasks with one value for each of the n rows of 
centers 
an integer indicating the number of centers in clustering. 
cluster.object 
an object generated from 
lambda 
the weight for the global l2norm 
sparse 
indicating whether the transformation results in a sparse matrix or not 
valid.x 
the mxp validation data matrix. 
valid.y 
if provided, it will be used to calculate the validation score with 
valid.metric 
the metric function for the validation result. By default it is the accuracy for classification. Customized metric is acceptable. 
type 
the type of the mission for 
cost 
cost of constraints violation (default: 1).
Rules the tradeoff between regularization and correct classification on data.
It can be seen as the inverse of a regularization constant.
See details in 
epsilon 
set tolerance of termination criterion for optimization. If NULL, the LIBLINEAR defaults are used, which are: 
bias 
if bias is 
wi 
a named vector of weights for the different classes, used for asymmetric class sizes. Not all factor levels have to be supplied (default weight: 1). All components have to be named according to the corresponding class label. 
verbose 
if set to 0, no information is printed.
If set to 1 (default), the running time and validation score (if applicable) will be printed.
If set to 2, the running time ,validation score (if applicable) and the 
seed 
the random seed. Set it to 
cluster.method 
The clusterign algorithm to use. Possible choices are
If 
cluster.fun 
The function to train cluster labels for the data based on given number of centers.
Customized function is acceptable, as long as the resulting list contains two fields named as 
cluster.predict 
The function to predict cluster labels for the data based on trained object.
Customized function is acceptable, as long as the resulting list contains two fields named as 
... 
additional parameters passing to 
svm

sparse
whether the data is sparsely transformed
label
the clustering label for training data
centers
the clustering centers from teh training dataset
cluster.fun
the function used for clustering
cluster.object
the object either
cluster.predict
the function used for prediction on new data based on the object
valid.pred
the validation prediction
valid.score
the validation score
valid.metric
the validation metric
time
a list object recording the time consumption for each steps.
