I am trying to install the flowViz package and it is saying that the dependency flowCore is not available even though it has just installed it.

I created a new directory, set the .libPaths() to point only to there and then called

source("https://bioconductor.org/biocLite.R")
biocLite("flowViz")

in the usual fashion. This installs all of the necessary dependencies - including flowCore - and then when it gets to flowViz itself it says flowCore is not found. The tail end of the output is below:

** R
** data
** inst
** byte-compile and prepare package for lazy loading
** help

** building package indices
** installing vignettes
** testing if installed package can be loaded
* DONE (flowCore)
* installing *source* package ‘flowViz’ ...
** R

Error : package ‘flowCore’ required by ‘flowViz’ could not be found
Error: loading failed
Execution halted
ERROR: loading failed

The downloaded source packages are in
    ‘/tmp/RtmpiDqYYK/downloaded_packages’
Warning message:
In install.packages(pkgs = doing, lib = lib, ...) :
  installation of package ‘flowViz’ had non-zero exit status
Calls: biocLite ... .biocLiteInstall -> .reposInstall -> install.packages

I can even load flowCore after that:

And yet flowViz still says it cannot be found.

I have recently upgraded to R 3.5.1 and I suspect the error is related to this rather than Bioconductor, however I haven't found any CRAN packages that produce a similar error.

I got the same results trying to install RBGL from Bioconductor where it installed the graph package and then said RBGL can't be installed because graph cannot be found.

I'm using Bioconductor 3.7.

Any help would be much appreciated,

Cheers

I think that .libPaths() has more than one entry, and that flowCore is installed in, e.g., the second entry. Try removing flowCore from all locations, and installing it again. Then try to install flowViz.
