Remove inappropriate arguments from an argument list
Takes a list of arguments and eliminates those that are not appropriate for passing to a particular function (and hence would produce an error if passed).
clean.args(argstr,fn,exclude.repeats=FALSE,exclude.other=NULL,dots.ok=TRUE) remove.args(argstr,fn)
argstr |
a named list of arguments, e.g. from \dots |
fn |
a function |
exclude.repeats |
(logical) remove repeated arguments? |
exclude.other |
a character vector of names of additional arguments to remove |
dots.ok |
should "..." be allowed in the argument list? |
clean.args returns a list which is a copy of argstr with arguments inappropriate for fn removed; remove.args removes the arguments for fn from the list.

tststr <- list(n=2,mean=0,sd=1,foo=4,bar=6)
clean.args(tststr,rnorm)
try(do.call("rnorm",tststr))
do.call("rnorm",clean.args(tststr,rnorm))
remove.args(tststr,rnorm)
