It provides the efficient data.table object which is a much improved and better performance version of the default ame. Use unique() function from data.table package to eliminate duplicates, data.table is a package that is used to work with tabular data in R Programming Language. If you wanted to get unique rows on selected columns of the R ame, just pass the columns as arguments to this distinct() function.Ĥ. is not distinct, this keeps the first row of values. keep_all=TRUE which keeps all variables in. Similarly, you can also use this to get duplicates rows on a single column. Note that we have the first 2 rows with duplicates (all column values) and the last two rows with duplicates on columns id, pages, chapters and price. If you already have data in CSV you can easily import CSV files to R DataFrame. Let’s create an R DataFrame, run these examples and explore the output.

Google Sheets doesn’t have an analogous Consolidate feature, but you can consolidate data manually or by using Paste Special as explained here.Df2 % distinct(id,pages. The result is total sales summarized by product, starting from cell E1.Ĭombine and Sum Duplicate Rows in Google Sheets If the data set doesn’t have a header row, you don’t need to select Top row. In the Consolidate window, check Top row, and Left column and click OK.Select the data range you want to consolidate (e.g., B1:C17), and press ENTER.In the Consolidate window, leave the default Function ( Sum), and click on the Reference icon to select the range for consolidation.Select the cell where you want to get a new data range (e.g., E1), and in the Ribbon, go to Data > Consolidate.In the following example, you have products in Column B (including duplicates), and their sales amounts in Column C.Ĭombine the data and get a total sales amount for every product in a separate range, next to the original one. For example, if you have sales by product in a sheet (as shown below), you may want to summarize sales for every product. In Excel, there is often a need to combine duplicate rows in a range and sum them in a separate column. This tutorial demonstrates how to combine duplicate rows by summing them in Excel.
