[R] Equation with double quotes from R to Excel?

[Sarah Goslee]

This doesn't answer your actual question, but isn't it better practice
to use ISBLANK instead of ""?

As for your actual question, a check of the parts of your command at
the R prompt would probably reveal something interesting:

> paste("IF(A2=", dQuote(""), ",", dQuote(""), ",1)", sep="")
[1] "IF(A2=“”,“”,1)"
> options(useFancyQuotes=FALSE)
> paste("IF(A2=", dQuote(""), ",", dQuote(""), ",1)", sep="")
[1] "IF(A2=\"\",\"\",1)"

This bit of your output should have been a hint:
IF(A2=Ҡ,Ҡ,1)

However, I have found that the Function “setCellFormula” doesn’t take the “” well while a “” in Excel equation stands for a blank cell.  I have tried NA(), EMPTY(), etc, and none of them are what I want.  Does anyone have other ways to put an equation with “” from R to Excel workbook?  Thanks in advance.
