Hi guys I am trying to learn use R for RNA-SEQ analysis and I am trying some functions and guides from bioconductor, however I am getting some errors.

http://www.sthda.com/english/wiki/rna-seq-differential-expression-work-flow-using-deseq2#introduction

One of them I quickly found a answer, because they change the name of the fuunction 8(.

But this error I didn't find any answer still:

    txdb <- makeTranscriptDbFromBiomart( biomart="ENSEMBL_MART_ENSEMBL",
                                         dataset="hsapiens_gene_ensembl" )
    Error in makeTranscriptDbFromBiomart(biomart = "ENSEMBL_MART_ENSEMBL",  : 
      could not find function "makeTranscriptDbFromBiomart"

I import the library as due

    library( "GenomicFeatures" )
But got that error.  
Any tip?
thanks

I got it done with makeTxDbFromBiomart...
well I guess they change the functions names a lot in R packages.
