Re: [R] matrix form

If you mean how to create a matrix like below, then you can code it as arm - 1:10 study - rep( 1:4, c(3,3,2,2) ) Num - c(2, 9, ...) df - cbind( arm, study, Num ) but this is really painful. If you have this information stored in Excel, save it as tab delimited or comma separated
