textTrain()

Train word embeddings to a numeric (ridge regression) or categorical (random forest) variable. 
textTrainLists()

Individually trains word embeddings from several text variables to several numeric or categorical variables. It is possible
to have word embeddings from one text variable and several numeric/categprical variables; or vice verse, word embeddings from
several text variables to one numeric/categorical variable. It is not possible to mix numeric and categorical variables. 
textTrainRegression()

Train word embeddings to a numeric variable. 
textTrainRandomForest()

Train word embeddings to a categorical variable using random forrest. 
textPredict()

Predict scores or classification from, e.g., textTrain. 
textPredictTest()

Significance testing correlations
If only y1 is provided a ttest is computed, between the absolute error from yhat1y1 and yhat2y1.
