Pipe operators, available in
dplyr, and other R packages, process a data-object using a sequence of operations by passing the result of one step as input for the next step using infix-operators rather than the more typical R method of nested function calls.
Note that the intended aim of pipe operators is to increase human readability of written code. See Remarks section for performance considerations.
