Description

opened on Feb 17, 2022

This would allow for more consistent syntax when extracting the type of an expression.

A block like this:

if (inherits(x, "Expression")) { class<-x$type()$ToString() } else { class<- type(x)$ToString() }

would be simplified to

class<- type(x)$ToString()

                              This would allow for more consistent syntax when extracting the type of an expression.
                              A block like this:
                              if (inherits(x, "Expression")) { class<-x$type()$ToString() } else { class<- type(x)$ToString() }
                              would be simplified to
                              class<- type(x)$ToString()
