Error during plotting of VPC

### Discussed in https://github.com/LAPKB/Pmetrics/discussions/259 <div type='discussions-op-text'> ^{Originally posted by **BoburaII** May 19, 2025} Hello, I’m attempting to plot VPCs using the `PM_result$valid$plot()` function, and I keep getting this error: valid1 <- res1$validate(limits = NA) res1$valid$plot() Error in `bind_cols()`: ! Can't recycle `..1` (size 9) to match `..2` (size 18). Run `rlang::last_trace()` to see where the error occurred. Could this be a data format issue? I’ve got two outputs in the dataset, with corresponding output equations in the model file. I’m able to plot a scatter VPC by extracting the simdata using `valid1$simdata$plot(obs = res$op)`. However, I need to generate a confidence interval VPC plot similar to the ones created using the example model/data files and I was hoping to accomplish this by using the `PM_result$valid$plot()` function. Any help with this would be greatly appreciated. Thanks! Bob </div>
