If STDEV is used on all items in a SELECT statement, each value in the result set is included in the calculation. STDEV can be used with numeric columns only. Null values are ignored. STDEV is a deterministic function when used without the OVER and ORDER BY clauses.
In the caret package, the subdirectory. has all the code for each model that train interfaces with and these can be used as prototypes for your model. Let's create a new model for a classification support vector machine using the Laplacian kernel function. We will use the kernlab package's ksvm function.ne limitation of train is that it requires the use of basic model formulas. There are several functions that use special formulas or operators on predictors that won't (and perhaps should not) work in the top level call to train. However, we can still fit these models.
