toolkit.deref

<code>deref(o, [a,b,c], d)</code> is a safe way of doing
<code>o[a][b][c]</code>. If that path does not exist, d is returned.
If d is not supplied, null is returned. Any undefined values in
path are ignored.

Web front end for your 'R' functions producing plots or tables.
If you have a function or set of related functions, you can make them
available over the internet through a web browser. This is the same
motivation as the 'shiny' package, but note that the development of
'shinylight' is not in any way linked to that of 'shiny' (beyond the use of
the 'httpuv' package). You might prefer 'shinylight' to 'shiny' if you want
a lighter weight deployment with easier horizontal scaling, or if you want
to develop your front end yourself in JavaScript and HTML just using
a lightweight remote procedure call interface to your R code on the
server.
