I can't install devtools: 

if (!require("devtools")) install.packages("devtools") 
devtools::install_github("rstudio/httpuv")

produces:

ERROR: dependency 'pkgload' is not available for package 'devtools' * removing 'C:/Users/R/win-library/3.3/devtools'

install.packages('pkgload')

creates:

Package which is only available in source form, and may need compilation of C/C++/Fortran: ‘pkgload’ These will not be installed –

You're using a relatively old version of R. Install the latest and try again – Hong Ooi

It can't seem to download some of the packages that devtools depends on. Try the following and see if it works-

devtools::install_github(repo = "r-lib/devtools",
                         dependencies = TRUE,
                         upgrade = TRUE)

If you don't have devtools on your system, download remotes from CRAN and then repeat the exact code as above 

   remotes::install_github(repo = "r-lib/devtools",
                             dependencies = TRUE,
                             upgrade = TRUE)
