Webfroll* functions accepts vectors, lists, data.frames or data.tables. They always return a list except when the input is a vector and length (n)==1 in which case a vector is returned, for convenience. Thus rolling functions can be used conveniently within data.table syntax. WebR If statement executes a set of statements based on a given condition. If the condition in If-statement evaluates to TRUE, then the statements in the If block execute, else not. In this tutorial, we will learn about R If statement and how does this help in decision making with syntax, flow diagram and examples. Flow Diagram

WebSince we've added the new value of NA at x [11, 1] to sum, it will from that index forward be equal to NA, which is exactly the result we would expect if we implemented a rolling sum function in R using the same single pass summation algorithm described above that doesn't account for NA's.
