Here is what it take to write out two sheets with XLConnect
# function to write out a sheet to an EXCEL file that I use
f.writeXLSheet <-
function (data, sheet, fileToWrite, rownames = NULL)
{
require(XLConnect)
writeWorksheetToFile(fileToWrite, data = data, sheet = sheet,
rownames = rownames, styleAction = XLC$STYLE_ACTION.NONE)
}
df1 <- data.frame(c1=1:2, c2=3:4, c3=5:6)
df2 <- data.frame(c21=c(10.10101010101,20, 3), c22=c(50E50,60, 3) )
outFile <- 'df12.xls'
unlink(outFile) # make sure there is no file to start with
f.writeXLSheet(df1, 'df1', outFile)
f.writeXLSheet(df2, 'df2', outFile)
I have attached the resulting Excel file (see how far it makes it).
