I installed new package and added library GenomicFeatures. One of the changes in version 1.20 is renamed function makeTranscriptDbFromGFF() to makeTxDbFromGFF(), but using this new name I got an error that function cannot be found. Can you tell me why? (Btw, old function works fine)
I follow with RNA-seq workflow from http://www.bioconductor.org/help/workflows/rnaseqGene/ and using exonsBy() function I cannot extract exon_name (instead of exon names this function generates NA). Any idea why?

Can you give us the output of
packageVersion("GenomicFeatures")orsessionInfo()after you have loadedGenomicFeatures?I checked and it is ‘1.18.7’, but why if I installed it few hours ago using
source("http://bioconductor.org/biocLite.R") biocLite("GenomicFeatures")Output from sessionInfo()
