Cannot run Predict on a lrm output

data analysis modeling strategy

Hello,

I fitted a logistic regression model using lrm some days back and computed predictions using both rms::Predict and stats::predict with no problems. However, I have been having problems since yesterday with the following message

Error in reformulate(attr(termobj, “term.labels”)[-dropx], response = if (keep.response) termobj[[2L]], : ‘termlabels’ must be a character vector of length at least one

Using the predict in the stats package returned the same error. Anyone else has the same experience?

Hi Lainei - questions about the rms package go in datamethods.org/rms - please copy this question there as a reply to the last reply and I’ll remove it here. Please also include the simplest code example that fails. That will help me debug. Thanks.
