write.xls

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).

Hello, All:


      The "writeFindFn2xls" function in the "sos" package tries to write
an
Excel file with 3 sheets ('PackageSum2', 'findFn', 'call').
Unfortunately,
it is often unable to do this because of configuration problems that are
not
easy to fix.  I've found 3 contributed packages that provide facilities
to
write Excel files with multiple sheets. Unfortunately, I can't get any
of
them to work consistently for me. Below please find test cases that
illustrate the problems.  Any suggestions for how to solve this problem
will
be appreciated.


      Thanks,

library(dataframes2xls)

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'

write.xls(c(df1,df2), outFile)
# works

do.call(write.xls, list(c(df1, df2), outFile))
# Error in get(s[i]) : object 'structure(list(c1=1:2' not found

Try this:

dd<- list(df1 = df1, df2 = df2)
do.call("WriteXLS", list("dd", outFile))

or this:

do.call("WriteXLS", list(c("df1", "df2"), outFile)

That was for WriteXLS.  For dataframes2xls try this:

do.call("write.xls", list(quote(c(df1, df2)), outFile))

Hi, Gabor:  Thanks.  I think we're gaining on it, but I'm still not quite
there.  Consider the following extension of my previous toy example:

library(dataframes2xls)

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'

write.xls(c(df1,df2), outFile)
# works

do.call(write.xls, list(quote(c(df1, df2)), outFile))
# works

df2x<- function(x, file)
    do.call(write.xls, list(x, file))
df2x(quote(c(df1, df2)), outFile)
# works

df2<- function(x1, x2, file){
    x23<- quote(c(x1, x2))
    do.call(write.xls, list(x23, file))
}
df2(df1, df2, outFile)
# Error in get(s[i]) : object 'x1' not found


      This is closer to what I need.  The answer may lie in getting the right
"envir" argument for "do.call".  However, I haven't yet found something that
works there.


      Thanks,
      Spencer
