I wrote a script in R to do some analysis and make the result as a set of table in xlsx format.
However, I would like to have some automatically generated default graphics from these tables in another sheet.
one way is using
addPicture(file, sheet, scale=1, startRow=1, startColumn=1)
from the xlsx package. meaning generating this plots using R and saving them separating and inserting them in to the excel file.
I wonder, if there is any easier way, using excel functionality. For example if there is any formula for generating these plots to do so ?
Basically, I wonder, if there is any automatic scripting way to generate these graphs ? is there any way, like a formula to do such a thing ?

I am trying to write to an excel file that needs to be uploaded somewhere. The target software creates an excel file which has an XML map attached to it. I recreated the entire file structure in R using code, but any time I try to write to that excel file, i think R actually deletes the old file and creates a new one instead, because the XML map is gone the moment I start writing any data to it. Loading up the workbook also doesn't seem to bring in the xml map, only the workbook data and sheets.
Is there a way to write data to this existing file within R (or python) without losing the XML map? Now i need to generate a file and manually copy paste the data into the other excel file.
I've been trying with xlsx, readxl, xml2 packages.
In the past Ive deal with a similar problem. To my knowledge, almost all the R packages that interact with excel replace the entire file with a new one. Except the openxlsx package. You can replace specific sheets, and range of cells, whitout touching the rest (data, styling , etc..). One last comment is that I dont know much about XLM maps, but maybe you are lucky.
Here is the vignette:

Hope it helps
I would like to read the formulas inside a workbook using R. I have an excel file called "link.xlsx" with value 1 at cell A1 and another excel file called "myFile.xlsx" with value A1=[link.xlsx]Tabelle1!$A$1. I tried the following:
library('XLConnect')
wb<-loadWorkbook("myFile.xlsx")
getCellFormula(wb,1,1,1)
I get
[1]Tabelle1!$A$1
and not
[link.xlsx]Tabelle1!$A$1.
1) How I can fix the problem?
2)Is there a way to quickly get the list of external reference workbooks (linked excels) using R?
UPDATE: For the moment, I found a solution using the approach explained here:
Extract hyperlink from Excel file in R
but I still wonder if it is possible to solve the problem into a more compact way.
I am trying to automate some of my tests in R to produce a static report in Excel. I have created a template in Excel which has a few charts and tables(sheet 1).
Now I run my R code to generate the data to fill in the same excel template file on Sheet 2.
I am using Openxlsx package to loadworkbook(excel template), next I overwrite data in sheet 2 by deleting the sheet and recreating it again with the new data so that the excel template has data for new test runs.
This runs without any error. But when I open my excel back the charts disappear with the !REF# error whereas as the tables are overwritten properly in the template(sheet1).
Has anyone come across such a scenario? The method I am using is a bit weird but can't think of any other alternative.
Thanks in advance!!
This definitely sounds weird. Something seems off, but I'm sorry I can't tell you what the issue may be. Anyway, I would say, just use R to generate the data and dump everything into Excel. Then, run some VBA in Excel to create the charts. I have no idea what your VBA skills are like, but I'm guessing it would be much easier to crate charts in Excel using VBA, rather than trying to do all of this with R.

I am wondering is it possible to read an excel file that is currently open, and capture things you manually test into R?
I have an excel file opened (in Windows). In my excel, I have connected to a SSAS cube. And I do some manipulations using PivotTable Fields (like changing columns, rows, and filters) to understand the data. I would like to import some of the results I see in excel into R to create a report. (I mean without manually copy/paste the results into R or saving excel sheets to read them later). Is this a possible thing to do in R?
UPDATE
I was able to find an answer. Thanks to awesome package created by Andri Signorell.
library(DescTools)
fxls<-GetCurrXL()
tttt<-XLGetRange(header=TRUE)

Copy the values you are interested in (in a single spread sheet at a time) to clipboard.
Then
dat = read.table('clipboard', header = TRUE, sep = "\t")
You can save the final excel spreadsheet as a csv file (comma separated).
Then use read.csv("filename") in R and go from there. Alternatively, you can use read.table("filename",sep=",") which is the more general version of read.csv(). For tab separated files, use sep="\t" and so forth.
I will assume this blog post will be useful: http://www.r-bloggers.com/a-million-ways-to-connect-r-and-excel/
In the R console, you can type
?read.table
for more information on the arguments and uses of this function. You can just repeat the same call in R after Excel sheet changes have been saved.
