package or namespace load failed for 'shiny' - r

When I am trying to install shiny in R studio I am getting this error
there is no package called 'httpuv'
, so I tried using package.install('httpuv') but here I got something like
In install.packages("httpuv") :
installation of package 'httpuv' had non-zero exit status
After that I tried to library(shiny) to get load shiny but still got the same error that httpuv is missing below.
library(shiny)
Error: package or namespace load failed for 'shiny' in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
there is no package called 'httpuv'

I'm trying to make use of the R package "snippets." So, I seem to have installed it ok:

But then, when I go to add it to my library, I get the following error message:

R: Error when loading package C50

I am receiving the below error when calling the 'C50' package. It has been installed correctly.
Error: package or namespace load failed for ‘C50’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
there is no package called ‘inum’
I have also ran the following .lib path code prior to installing and calling the library:
.libPaths(c("C:/Users/danhu/OneDrive/Documents/R/win-library/3.4", .libPaths()))
Any thoughts on why this might be happening?

You can install by using a code:
install.packages("C50", repos="http://R-Forge.R-project.org")
library(C50)
visit:https://rdrr.io/rforge/C50/

Error in require(biwavelet)

I have just downloaded biwavelet package but when trying to open it in R version 3.1.2 i get this error message:
> library(biwavelet)
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) :
there is no package called ‘spam’
Error: package or namespace load failed for ‘biwavelet’
It only happens with this package. Any clues about what is the problem here?

It seems to be missing a dependency somehow. Just run
install.packages("spam")
to install the missing package.
