WebMar 24, 2024 · I have created a nomogram in R using the nomogram function from the rms package but, due to the "Total Points" default range being from 0 - maximum possible value it is very difficult to see and thus interpret the predicted probabilities.. I would like to be able to truncate the "Total Points" to range from 250-350 but I really don't know how to do this. Websummary.rms forms a summary of the effects of each factor. When summary is used to estimate odds or hazard ratios for continuous variables, it allows the levels of interacting factors to be easily set, as well as allowing the user to choose the interval for the effect. This method of estimating effects allows for nonlinearity in the predictor.
