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))
