duplicates

问题 I'm trying to find a speedier replacement for finding duplicates in R. The intent of the code is to pass the matrix to Rcpp with a row number from that matrix, then loop through the entire matrix looking for a match for that row. The matrix in question is a Logical matrix with 1000 rows and 250 cols. Sounds simple, but the code below is not detecting equivalent vector rows. I'm not sure if it's an issue with the equal() function or something in how the matrix or vectors are defined. #include

问题 I have an text document of emails such as Google12@gmail.com, MyUSERNAME@me.com, ME@you.com, ratonabat@co.co, iamcool@asd.com, ratonabat@co.co, I need to check said document for duplicates and create a unique array from that (so if "ratonabat@co.co" appears 500 times in the new array he'll only appear once.) Edit: For an example: username1@hotmail.com username2@hotmail.com username1@hotmail.com username1@hotmail.com username1@hotmail.com username1@hotmail.com This is my "data" (either in an

问题 I have a spreadsheet as below: combine duplicates I can merge the duplicates by using the script here. However, I have no idea to add the column A to the merged column (K) . Any help appreciated! Thanks 回答1: Assuming that row 1 is the header row so actual data starts on row 2, and you want the output to start in cell J2, this code should work for you: Sub tgr() Dim cllSKU As Collection Dim SKUCell As Range Dim rngFound As Range Dim arrData(1 To 65000, 1 To 2) As Variant Dim strFirst As String

问题 I have an administrative dataset for store visits from multiple years that I am trying to merge into one under the ID variable. Each dataset has duplicates of an ID that occur during different store visits, annotated by Date . Some of the more recent data files also have new variables ( Y ) not contained in the old data files. Datasets from different years will also contain different cases indicated by different ID . Also, some variables may be the same for each case but at different dates. I

问题 Using the following reproducible example: ID1<-c("a1","a4","a6","a6","a5", "a1" ) ID2<-c("b8","b99","b5","b5","b2","b8" ) Value1<-c(2,5,6,6,2,7) Value2<- c(23,51,63,64,23,23) Year<- c(2004,2004,2004,2004,2005,2004) df<-data.frame(ID1,ID2,Value1,Value2,Year) I want to select rows where ID1 and ID2 and Year have the same value in their respective columns. For this rows I want to compare Value1 and Value2 in the duplicates rows and IF the values are not the same erase the row with the smaller

问题 I need to pick few random values from ArrayList , but values cannot duplicate. With code below i simply pick random values but they can duplicate. for (int i = 0; i < 5; i++) { index = random.nextInt(menuItems.size()); HashMap<String, String> urls = new HashMap<String, String>(); urls.put("Value", menuItems.get(index).get(KEY_URL)); randomitems.add(urls); } 回答1: If you don't need to keep menutItems in a specific order, you can simply shuffle it and take the first 5 items: Collections.shuffle

问题 I recently switched out log4net logging from using config files to being set up programmatically. This has resulted in the nhiberate entries getting repeated 2 or sometimes 3 times. Here's the code. It uses a string which looks something like this "logger1|debug,logger2|info" private void SetupLog4netLoggers() { IAppender appender = GetAppender(); SetupRootLogger(appender); foreach (string logger in Loggers) { CommaStringList parts = new CommaStringList(logger, '|'); if (parts.Count != 2)

问题 I have a table in MySql with a list of keywords. Each keyword was stored in a new row once it was entered by a user on this site. I have the following query in PHP: SELECT * FROM keywords GROUP BY query Which gets all the keywords from MySql, and only shows one of each incase of duplicate keywords. So the output is something like: Dog Cat Lion Fong When I'm using $update['query']; But I'd like to count how many times each keyword appears in the database, so the output would be, for example:
