Installing shiny

Hi,

I tried to install a shiny package but I keep getting an error below. Could anyone help what this means?

Thank you!

ERROR: dependencies 'later', 'promises', 'rlang' are not available for package 'shiny'

It means that you need to install those packages before installing shiny

pkgs = c('later', 'promises', 'rlang') 
install.packages(pkgs)

Thank you for the advise. Unfortunately, my computer does not have any compilers to compile these stated below. Do you know if I could get a complied package?

pkgs = c('later', 'promises', 'rlang')
install.packages(pkgs)
Packages which are only available in source form, and may need compilation of C/C++/Fortran: ‘later’ ‘promises’ ‘rlang’
These will not be installed

In which operating system are you? if you are on windows you may want to install Rtools

I am on windows and I don't think I have Rtools. Let me install this.
Thank you for your help!

You may also want to consider updating your R to the latest version. Pre-compiled binaries are only made available for current (and sometimes current-minus-one) versions of R, so running older versions tends to mean you have to do a lot more package compiling.
