Hi Cem,
You may find it easier to use the do.call method and the clean.args
function:
library(plotrix)
parametric.tests<-function(testfun,arglist) {
result<-do.call(deparse(substitute(testfun)),
clean.args(arglist,testfun))
return(result)
}
parametric.tests(mean,list(x=1:5,na.rm=TRUE,foo="?"))
If the function called ("testfun") is available, and the argument
"arglist" contains sufficient arguments for it to run, it will return
the value of the function. The reason for using "clean.args" is in case
you are passing a fixed list of arguments, all of which may not be
appropriate for any of the functions that you want to pass as "testfun".
