+#' linear SVM Model
+#'
+#' Fits an linear SVM model against a SparkDataFrame. It is a binary
classifier, similar to svm in glmnet package
+#' Users can print, make predictions on the produced model and save the
model to the input path.
+#'
+#' @param data SparkDataFrame for training.
+#' @param formula A symbolic description of the model to be fitted.
Currently only a few formula
+#' operators are supported, including '~', '.', ':', '+',
and '-'.
+#' @param regParam The regularization parameter.
+#' @param maxIter Maximum iteration number.
+#' @param tol Convergence tolerance of iterations.
+#' @param standardization Whether to standardize the training features
before fitting the model. The coefficients
+#' of models will be always returned on the
original scale, so it will be transparent for
+#' users. Note that with/without standardization,
the models should be always converged
+#' to the same solution when no regularization is
applied. Default is TRUE, same as glmnet.
+#' @param threshold The threshold in binary classification, in range [0,
1].
+#' @param weightCol The weight column name.
+#' @param ... additional arguments passed to the method.

I don't think that would hurt. We have expert params in tree models.
