Install phyloseq in qiime2 docker container

Hi,

I'm currently trying to install the R package 'phyloseq' in your Qiime2 2017.12 docker container. I have tried using the conda install -c bioconda bioconductor-phyloseq=1.22.3 command. It gives me a list of the dependencies that requires endless installation.

I have also tried to install it using these two methods in the R 3.4.1:

install.packages("devtools")
library("devtools")
install_github("phyloseq", "joey711")
library(phyloseq)

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

I still couldn't install it in the container. Could you please point me to the right way to install the phyloseq package in the qiime2/core:2017.12 container?

Thanks,
Changsu
