[R] Getting the C-index for a dataset that was not used to generate the logistic model

different coefficients to the variables). It doesn't simply apply the new data to the model from * logit.lrm* that I generated before. So, can someone point me in the right direction for evaluating the model that I built with trainingData, but getting the C-statistic against my validationData?
