Note

A typical use for this flag is forcing Excel into updating formulas that reference cells affected by writeWorksheet or writeNamedRegion. The exact behavior of Excel when the flag is set depends on version and file format.

Examples

if (FALSE) { # \dontrun{
# mtcars xlsx file from demoFiles subfolder of package XLConnect
demoExcelFile <- system.file("demoFiles/mtcars.xlsx", package = "XLConnect")

# Load workbook
wb <- loadWorkbook(demoExcelFile)

# Tell Excel to automatically recalculate formulas on sheet mtcars
setForceFormulaRecalculation(wb, sheet = "mtcars", TRUE)
# The same with a numerical sheet index
setForceFormulaRecalculation(wb, sheet = 1, TRUE)
} # }
