I'm having a hard time fathoming your question, since "pterms" appears
nowhere in my source code to residuals.survreg. Can we start at the
beginning, per the posting guide?
1. What version of R are you running?
2. What exactly are the statements you typed which give the message?
Note that residuals are not saved in a fit, but are computed later.
fit <- survreg(Surv(time, status) ~ age + height, data=mydata)
--- begin included message --------
Residual and predict methods are not carried out on the
object, although the component linear.predictors exists for
survreg object. Looking at the code I see that the residual
refuses to run if any of the components of the pterms vector
