I suggest NOT using "XLConnect". "sos" now uses WriteXLS. "Ecfun"
now uses "openxlsx".
Also, I received an email from CRAN maintainers months ago saying
that "gdata" was being obsoleted. It's still on CRAN with a date of
2017-06-06 and a huge number of reverse dependencies. The CRAN
maintainers may have gotten someone to agree to take it over who just
hasn't finished fixing whatever deficiencies it has. However, you might
see how difficult it might be to do without "gdata" as well.

inside teh functions tehre is an ' @importFrom XLConnect createSheet

The package is usable without XlConnect if I change
Imports: igraph,chron,gdata, XLConnect
to
Imports:
igraph,chron,gdata
Suggests:XLConnect
but then I get the error
checking package dependencies ... ERROR
Namespace dependency not required: ‘XLConnect’
Just now the new version is on my private repository and working with or
without Xlconnect depending on the java version
How can I submit the package to cran until XlConnect is working with
java > 11
You should not have
@importFrom XLConnect createSheet writeWorksheet saveWorkbook
in your ROxygen comments; that results in an unconditional import.
Instead, you should use fully qualified calls each time, i.e.
XLConnect::createSheet, XLConnect::writeWorksheet, XLConnect::saveWorkbook
in your code. You should also wrap every use of those functions in
checks like
if (requireNamespace("XLConnect")) {
run code
} else {
report that you can't run that code
}
and make sure none of your examples or vignettes fail if XLConnect is
not present.
