Hello dear, I am really new to all this so forgive me if I am not clear.  I am trying to install TxDb.Hsapiens.UCSC.hg19.knownGene, but keep getting the error below : installation had non-zero exit status and the package is not installed.  My R and Bioconductor installations were all withing the past 2 weeks so I assume everything is updated.  Below is the error and then the session info,

Usually installing a package will install its dependencies. For some reason this is not the case for your installation, leading to the error

Error: package or namespace load failed for 'GenomicFeatures' in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
 there is no package called 'stringi'
Error : package 'GenomicFeatures' could not be loaded

So correct that

biocLite("stringi")

and try again

biocLite("TxDb.Hsapiens.UCSC.hg19.knownGene")
