Question

[mikysyc2016]

Hi, I use the following to install DiffBind.

biocLite("DiffBind")

But I can not istall it on my computer. How I can deal with it? Thanks.

library(DiffBind) Error: package or namespace load failed for ‘DiffBind’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]): there is no package called ‘bit64’.

[h.mon]

install.packages("bit64")
