Suppose we want to extract the same five variables as before from the CensusWorkers data set, but also add a factor variable based on the integer variable age. The additional lagged rows are removed from the original data vector before returning from the function. If you have variables that are already factors, you may covert change the order of the levels, the names of the levels, or how they are grouped. Another common use of factor recoding is in analyzing survey data gathered using Likert items with five or seven level responses.

If TRUEthe factor levels will be coded in the order encountered. Doing so will increase the size of the. You need to ensure that the two files, the training set and the test set, have compatible factor variables. The following call to rxDataStep will accomplish all of the above, returning a new data frame with the transformed variables:.

This depends on the. Email Xsf, but never shown. We compute a day moving average for the adjusted close adjusted for dividends and stock splits and plot it:.
