Hi I am trying to draw a PCA plot with DESeq2 but somehow I cannot use DESeq2 functions. It is a really simple code i wil be pasting below.

> transform <- DESeq2::rlog(eliminated_data, blind = TRUE)
Error in (function (classes, fdef, mtable)  : 
unable to find an inherited method for function ‘sizeFactors’ for signature ‘"spec_tbl_df"’

> DESeq2::plotPCA(eliminated_data,
+         intgroup = c('WT', 'Resistant'),
+         returnData = FALSE)
Error in (function (classes, fdef, mtable)  : 
unable to find an inherited method for function ‘plotPCA’ for signature ‘"spec_tbl_df"’

I couldnt figure out why is this happening? Thanks in advance

eliminated_data should be "a DESeqDataSet, or matrix of counts" (https://rdrr.io/bioc/DESeq2/man/rlog.html) and not a "spec_tbl_df" object. Please pay attention to your precedent code lines to obtain the desired output
