Any time you see an error that ends with

could not find function "<function name goes here>"

it means that you haven't loaded the package that contains that function yet. So start with library(DESeq2) and it will then work.

After run the library(DESeq2). Error: package or namespace load failed for ‘DESeq2’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]): there is no package called ‘locfit’
