loops

问题 I am still a relatively new user to R but am attempting to vectorize my for loops in order to increase computational speed. Currently, I need to perform two subsets on the data.frame/ data.table df (only named for this post): 1) subset by group id and 2) subset by each time interval interval for that particular id . I setup a nested for loop because I need to perform a homogeneity of variance test between each subset of data and a control using the levene.test in the lawstat package. The test

问题 1 2 3 4 5 6 7 8 9 I want to achieve above boxes position using absolute positioning and looping in js.

问题 Here is my code so far. I need to run the encode part of the code 5 times and then decode the encode the same number of times. I figured out how to encode the message but now I can't figure out how to run the "encode" or "decode" variable back through the code to strengthen the ecryption. public class Codes { /** * Encode and decode a message using a key of values stored in * a queue. */ public static void main(String[] args) { int[] key = {7, 6, 5, 2, 8, 5, 8, 6, 4, 1}; Integer keyValue;

问题 I have two sets of variables called ITEM 1 to ITEM 47, and another called L1 to L47. What I want to do is to calculate the sum of Ls if any ITEM#i=1. What I wrote is as following: COMPUTE LSUM=0. LOOP #i=1 to 47. IF (ITEM(#i)=1) LSUM=LSUM+L(#i). END LOOP. But I got an error message saying the characters do not match any existing function or vector. What should I do then? Your inputs will be very appreciated. Thanks. Sincerely, Lucy 回答1: COMPUTE LSUM=0. exe. vector vitems = ITEM 1 to ITEM 47.

问题 I am working on a logic app that will create users in third party applications based on AAD group membership. To avoid issues when the group has more than 999 users I have implemented paging. I first get the first 50 users, and a NextLink that I call to get the next 50. This loop runs fine. Snippet of logic app When no more nextlink is found, the loop exits.
