magrittr tee operator
Pipe a value forward into a function- or call expression and return the original value instead of the result. This is useful when an expression is used for its side-effect, say plotting or printing.
lhs %T>% rhs
- A value or the magrittr placeholder.
- A function call using the magrittr semantics.
The tee operator works like
%>%, except the
return value is
lhs itself, and not the result of
rnorm(200) %>% matrix(ncol = 2) %T>% plot %>% # plot usually does not return anything. colSums
