[R] Is it possible to create highly customized report in *.xls format by using R/S+?

[Gabor Grothendieck]

Here is an example where R is the client and Excel is the server 
so that R is issuing commands to Excel.  This example uses the 
RDCOMClient package from www.omegahat.org:

	library(RDCOMClient)
	xl <- COMCreate("Excel.Application")  # starts up Excel
	xl[["Visible"]] <- TRUE                       # Excel becomes visible
	wkbk <- xl$Workbooks()$Add()          # new workbook

	# set some cells

	sh <- xl$ActiveSheet()

	x12 <- sh$Cells(1,2)
	x12[["Value"]] <- 123

	x22 <- sh$Cells(2,2)
	x22[["Value"]] <- 100

	x31 <- sh$Cells(3,1)
	x31[["Value"]] <- "Total"

	B3R <- sh$Range("B3")
	B3R[["Formula"]] <- "=Sum(R1C2:R2C2)"
	B3R[["NumberFormat"]] <- "_($* #,##0.00_)"
	B3RF <- B3R$Font()
	B3RF[["Bold"]] <- TRUE


	# save and exit
	wkbk$SaveAs("\\test.xls")
	xl$Quit()

Code using the rcom package at (second link is mailing list):

	http://sunsite.univie.ac.at/rcom/download/
	http://mailman.csd.univie.ac.at/pipermail/rcom-l/

would be nearly identical once the upcoming version of rcom comes out.  
rcom and omegahat both provide the possibility of having
Excel as the client and R as the server; however, in that setup the
user would have to have R running whereas in the above setup only you do.
