问题 I have created dozens of data frames in R and would like to append them all to one sheet in an Excel file. Here are two of the pages I have looked at in an attempt to find an answer (I don't have 10 reputations so I can't paste all four webpage urls I have visited): Write data to Excel file using R package xlsx The author says: "You can also add the dataframes to a particular starting place in the sheet using the startRow and startCol arguments to the addDataFrame function."

问题 I have one question. Am I right that if I have a workbook which is created through xssf constructor then it is enough to change the constructor to sxssf workbook (with xssf wb passed as an argument) to make it work in a stream mode ? Thanks a lof for your answers. Solution: It all depends on the classes which you use for streaming. If your class gathers more stream buffers than it can hold, this thing won't work. Otherwise it will 回答1: Yes, you're right. The difference between these two

Package for connecting R and Excel without the Java Virtual Machine

由 孤街浪徒 提交于 2019-12-07 02:28:45
问题 A couple of months ago I found on the Internet information about an R package to connect R with Excel and the other way around (doing basically what xlsx and XLConnect do). However, the main difference with respect to the two above mentioned solutions was that the package wasn't designed to use the JVM (which keeps giving me some trouble). I've been spending quite some time trying to find the reference for that package, without success. Can you help me? Many thanks. 回答1: You may want to check

由 隐身守侯 提交于 2019-12-07 01:07:29
问题 I am trying to create cells comments using apache poi. I am able to create the comments, but by default they are always displayed in excel. I have to manual right click on the cell and un-tick show comments to make them invisible(now they appear only when I hover on the cell). Is it possible to make cell comments invisible by default(so that they don't appear in the excel until user hover over the cell.) Here is the code I used : Drawing drawing = cell.getSheet().createDrawingPatriarch();

Unreadable content message with Jasper and .xlsx

由 寵の児 提交于 2019-12-06 16:47:56
I have the following code that exports a xlsx to a stream. It works and I get the xlsx file but it says excel found unreadable content in "..." and asks if I want to recover the contents of the workbook. When I do so, I get the xlsx file with the correct data, in the correct places, as I wanted. How can I avoid or supress this error? try { ServletOutputStream servletOutputStream = resp.getOutputStream(); JasperReport jasperReport = JasperCompileManager .compileReport(path + "Template/Instructions_with_CHGFOX_Template/testeXlsx2.jrxml"); JasperPrint print = JasperFillManager.fillReport

AngularJS ui-grid import XLSX data best approach

由 混江龙づ霸主 提交于 2019-12-06 16:19:12
What would be the best approach to import XLSX data to be displayed using an AngularJS ui-grid? Is the js-xlsx parser a good choice for this, or are there other open source XLSX parser tools better suited for this task? In my case the XLSX data is very basic, nothing complicated, but I would like to preserve the style info as much as possible. I anticipate the the data grid will be less than 20 col x 1000 rows. Or would it be better to use an alternative data grid, such as the Hansontable, instead of ui-grid? Would that be better suited for spreadsheet data? Importing data into the grid with
