Has the spreadsheet created by R been opened in Excel and saved before you read it with Perl ?

see this note in the R package openxslx http://cran.r-project.org/web/packages/openxlsx/openxlsx.pdf (page 34)

Formulae written using writeFormula to a Workbook object will not get picked up by read.xlsx().
This is because only the formula is written and left to be evaluated when the file is opened in Excel.
Opening, saving and closing the file with Excel will resolve this.
