Web2 Actually we can check this is true using the following two facts: curl of a gradient field is zero. cross product of two parallel vector fields is zero. I am assuming your r ^ = ( x, y, … WebAs of version 2.3 curl connections support open (con, blocking = FALSE) . In this case readBin and readLines will return immediately with data that is available without waiting. For such non-blocking connections the caller needs to call isIncomplete to check if the download has completed yet.
