I came across this package and when I tried to install it, some commands didn't appear to exist/ usage was not accepted. I then started looking at help page for this package and they appeared different commands compared to the ones on the tutorial. I then looked at the versions and when I install using biocLite, it appears to be downloading version 1.2.0 instead of 1.4.1 as mentioned on the bioconductor page. Can this be updated please? Please see sessionInfo()
