partial display of labels seems not working in biplot function selectLab parameter

[persicomaria]

Hello I am experiencing the following issue:
I have pca results from a huge dataset but I want to display only a portion of the labels in a scoreplot (p$rotation object); I wiah to display only labels extracted from a clustering procedure so a subset of rownames(p$rotation ) belonging to let say cluster X.

here a toy example (still not working)

data(iris)

Perform PCA on the iris dataset (excluding the species column)

pca_result <- pca(iris[, 1:4], metadata = iris$specie)

Subset of rows to plot (for example: points 1, 50, and 100)

subset_indices <- c(1, 50, 100)

biplot(pca_result,
lab = rownames(iris[, 1:4]), # Pass all labels from the full dataset
selectLab = subset_indices, # Only label the subset of points (indices)
showLoadings = TRUE, # show variable loadings
colby = iris$specie, # Optionally color by metadata column
shape = iris$specie, # Optionally shape by metadata column
pointSize = 5, # Customize point size
legendPosition = 'right')

Error in (function (..., row.names = NULL, check.rows = FALSE, check.names = TRUE, :
arguments imply differing number of rows: 4, 150

I am working with rstudio associated to R4.4.1 and with latest version of PCA tools
Thanks in advance for your advice. Kind regards, Maria
