Error in batch_sil() and pcRegression()

[aditisk]

Hello,

I am following the steps in the tutorial and I was able to get an output for the kBET() function on my dataset. I'm running into some issues in the subsequent functions:

batch.silhouette <- batch_sil(pca.data, meta$sample_id)
Error in silhouette.default(as.numeric(batch), dd) :
clustering 'x' and dissimilarity 'dist' are incompatible

batch.pca <- pcRegression(pca.data, meta$sample_id)
Error in model.frame.default(formula = rot.data ~ batch, drop.unused.levels = TRUE) :
variable lengths differ (found for 'batch')

I'm using the same data and batch variables I used in the kBET() function. Any thoughts of what might be going wrong and how I can fix this ? Thanks a lot.
