#------ Load libraries ---------
library(rmarkdown)
library(plyr)
library(stringr)
library(dplyr)
library(highcharter)
library(DT)
library(reshape2)
# library(Kmisc)
library(plotly)

#----- 1. create the report directory ------------------------
system(paste0('mkdir -p ', opt$deseq_visualization_dir))


#----- 2. generate Rmd files with Rmd templates --------------
#   a. templates without placeholder variables:
#         copy templates from tool directory to the working directory.
#   b. templates with placeholder variables:
#         substitute variables with user input values and place them in the working directory.


#----- 01 DESeq_visualization.Rmd -----------------------

#-------4. manipulate outputs -----------------------------
