Tee pipe

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.

Usage

lhs %T>% rhs

Arguments

lhs

A value or the magrittr placeholder.

rhs

A function call using the magrittr semantics.

Details

The tee pipe works like %>%, except the return value is lhs itself, and not the result of rhs function/expression.

%>%, %<>%, %$%

Examples

rnorm(200) %>%
matrix(ncol = 2) %T>%
plot %>% # plot usually does not return anything. 
colSums

#> [1] -10.48309 -18.38497
