Dear Rxperts, Through Windows OS, I created shortcuts (paste as shortcut) to excel spreadsheets ( with "xlsx" as the file extension). I wasn't able to read the shortcuts through R and using "read" functions of "xlsx" package. exf <- "a1.xlsx.lnk" > read.xlsx(exf,1) Error in .jcall("RJavaTools", "Ljava/lang/Object;",

I have several hundred Excel 2007 data files in a folder. I would like to read every file in a single given folder using a loop. I have searched the FAQ, the forum archives here, other or older R boards and the R Import / Export documentation, and have asked some very knowledgeable R users without learning of a solution. I hope someone here can help. I understand that the most common

I?ve got an Excel workbook with about 30 worksheets. Each worksheet has 10000 rows of data over 30 columns. I?d like to read the data from each worksheet into a dataframe or matrix in R for processing. Normally, I use read.csv when interacting with Excel but I?d rather manipulate a multisheet workbook directly than set about splitting the original workbook and saving down each part as a csv.

HI, I have large dataset of many countries. I have written the program to run through each country to generate one output for each country. I want to put the output like this: one sheet has output for one country. How do I achieve it by r.

Hi to all. I have a problem to connect to an Excel database using RODBC. Namely, I am using 64-bit R 2.14.0, under Windows 7 and I tried following: library(RODBC) > channel <- odbcConnectExcel("results.xlsx") Error in odbcConnectExcel("results.xlsx") : odbcConnectExcel is only usable with 32-bit Windows # ok this is clear why it doesn't work > channel

Hallo all, I`ve read a lot of things in this forum about an Excel export via R. It is no problem to export my data frames via write.table or write.xls (xls or csv), but some things are not very convenient for me: I always have to adjust the column with to see all the numbers or the text and there is no frame between the cells. And I missing the possibility to make some headers bold or coloured.

Hi, I need some help to export a data frame with 83 rows and 1411 colums. I have used the package RODBC until now. But now, I have 1411 colums that I can't send to the old excel.

Hi List, just to know if the issue is only a problem of mine or if it is a general issue due to the new MS Office pack. I'm using R 2.11.1 32 bits in a Windows 7 x64 with the MS office 2010 x64 installed. I can import .xls files normally (the same way I did with my Excel 2007 32 bits). But the function odbcConnectExcel2007 isn't able to import .xlsx files now that I have the new version of

Hi, I tried to read xlsx files by "XLConnect" packages, but the dates are one day earlier than it is supposed to be. I moved from California to Taiwan (Eastern Asia), and it worked well in California, but not in Taiwan. Even if I adjust my Mac time to California time zone, it gives the wrong dates. I don't know which part of the setting (in RStudio or in my Mac?) I should adjust.

I have installed Win 1.1.42 on Ubuntu10.04 and installed Excel2007 as part of MS Office 2007. I can open a non-password protected .xlsx file without a problem.

Verify that the CAPS LOCK key is off and be sure to use the correct capitalization." I am certain

Dear group, I am working on a rather big project where the output data frames have dimensions of 3000 x 15 or greater. We are using xlsx and xlsx2 to write the data.frames to Excel sheets. Since recently we get the following error, when trying to write the data frames to the excel sheets: Error in ls(envir = envir, all.names = private) : invalid 'envir' argument We figured out that

Hello, We have a problem with our Samba server (we tested with two versions 3.6.6 and 4.1.11). When a User edit an Excel file and saves, another user can not save this edited later. The temporary file named like 885E9010 will be created and Excel reports that this file can not be accessed. I have test it with Windows and Mac. Both have the same Problem.

Hola. En mi caso, no he podido resolver los problemas con el Java para usar XLConnect, que en los papeles me parece el mejor. Supongo que algo de la arquitectura del sistema o bien de la relación entre el Java, el R y el RStudio. Así que utilizo library(openxlsx) write.xlsx(datos, file = "EDA1.xlsx") #donde datos es el objeto que quiero guardar. Requiere instalar el RTools, según tipo y

I am reading dates in Excel2007 into R. Here are the functions I used: library(RODBC) channel<-odbcConnectExcel2007("myfile.xlsx") tmp<-sqlFetch(channel,"1",as.is=T) The dates in myfile.xlsx are all in this format: mm/dd/yyyy. But when I read it to R, some columns look like "yyyy-mm-dd 00:00:00", some columns look like "yyyy-mm-dd", and some

Hi, I am hoping to use the RODBC package to write a dataframe to an Excel .xlsx file. The dataframe contains at least one field with character elements that exceed 255 bytes, which appears to be the cell width limit in Excel. Below is example code and the warning message received: library(RODBC) d <-
