Subscript out of bounds with multiple output equations

[mhovd]

I suspect this is due to the regression line calculations.

Hi,
I’m trying to plot op from a PM_result object (res), using: res$op$plot(outeq = 2)
I get the error: Error in summary(mod)$coefficients[2, 2] : subscript out of bounds

This didn’t happen previously with the same model and data. The model has 3 output equations, plotting op with outeq = 1 or outeq = 3 is fine. I'm using Pmetrics 2.1.1, R4.3.1, and recently updated macOS sequoia.
I appreciate any help with this.
