I declared the environment of the function myfun to be NULL as follows: environment(myfun) <- NULL
Later on I called that myfun and got an error message because the function index() in the zoo package was called inside myfun and was not visible: Error in myfun(args) : couldn't find function "index" I tried to use zoo::index() instead of index(), but that did not work. In fact, zoo::index does not work even in the command line: > z<-ts(1:5) > z Time Series: Start = 1 End = 5 Frequency = 1 [1] 1 2 3 4 5 > index(z) [1] 1 2 3 4 5 > zoo::index(z) Error in loadNamespace(name) : package 'zoo' does not have a name space How can I qualify index() so that it is visible inside the body of myfun? Thanks for any suggestions, FS ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
