Re: [R] "unbind" matrix?

Convert your matrix to a data frame and use do.call(). ?do.call do.call(Myfunc, data.frame(yourMatrix)) You need to do the data frame conversion because do.call wants the arguments as a list and a data frame **is** a list (the columns are the list members) with a dim attribute (+ others). Bert
