[R] Detect numerical series

Hello, I am struggling with detecting successive digits in a numerical series vector. Here is an example: vec - c(1, 15, 26, 29, 30, 31, 37, 40, 41) I want to be able to detect 29, 30, 31 and 40, 41. Then, I would like to delete the successive digits from the vector. 1, 15, 26, 29, 37, 40

Re: [R] Detect numerical series

This was actually answered a couple times in StackOverflow. Someone and I indpendently wrote up the following function, stolen directly from the source for rle(). # extended version of rle to find all sorts of sequences # if incr=0, this is rle seqle- function (x,incr=1) { if
