Details

Writes data to the named region specified by name. Note that data is assumed to be a data.frame and is coerced to one if this is not already the case. The argument header specifies if the column names should be written. Note also that the arguments are vectorized and as such multiple named regions can be written with one call. In this case data is assumed to be a list of data objects (data.frame's).

Examples

if (FALSE) {
# Load workbook (create if not existing)
wb <- loadWorkbook("writeNamedRegion.xlsx", create = TRUE)

# Create a worksheet named 'mtcars'
createSheet(wb, name = "mtcars")

# Create a named region called 'mtcars' on the sheet called 'mtcars'
createName(wb, name = "mtcars", formula = "mtcars!$A$1")

# Write built-in data set 'mtcars' to the above defined named region
# (using header = TRUE)
writeNamedRegion(wb, mtcars, name = "mtcars")

# Save workbook (this actually writes the file to disk)
saveWorkbook(wb)

# clean up 
file.remove("writeNamedRegion.xlsx")
