NaN causes "error in fitter" with cph.calibrate from pkg Design
...hts, : NA/NaN/Inf in foreign function call (arg 6) In addition: There were 50 or more warnings (use warnings() to see the first 50) er(X, Y, strata = Strata, offset = offset, weights = weights, : The warnings are of two types. Here are the first ten: > warnings() Warning messages: 1: In groupkm(cox, Surv(y[, 1], y[, 2]), u = u, cuts = orig.cuts) ... : one interval had < 2 observations 2: In groupkm(cox, Surv(y[, 1], y[, 2]), u = u, cuts = orig.cuts) ... : one interval had < 2 observations 3: In groupkm(cox, Surv(y[, 1], y[, 2]), u = u, cuts = orig.cuts) ... : one interval had...

Updates to rms package
...redictor name has changed between models * Added ties=mean to approx( ) calls that did not have ties= specified * Added nlevels argument to bplot to pass to contour * Added par argument to iLegend - list to pass to par(). * Redirected ... argument to iLegend to image( ). * Fixed groupkm - was printing warning messages wrongly * Added new semiparametric survival prediction calibration curve method in val.surv for external validation; this is the first implementation of smooth calibration curves for survival probability validation with right-censored data * Fixed calibrat...

validation, calibration and Design
Hi R experts, I am trying to do a prognostic model validation study, using cancer survival data. There are 2 data sets - 1500 cases used to develop a nomogram, and another of 800 cases used as an independent validation cohort. I have validated the nomogram in the original data (easy with the Design tools), and then want to show that it also has good results with the independent data using 60
