Row-wise recurive function call
...L, 11L, 24L, 39L, 7L, 47L), D = c(40L, 32L, 16L, 26L, 0L, 18L, 2L, 48L, 21L, 10L)), .Names = c("A", "B", "C", "D"), class = "data.frame", row.names = c(NA, -10L)) I have a function that works off EVERY individual ROW to throw a result. Like playFn <- function (x){ + result = ((x$A+6*x$B)/(3*x$C)+20)*x$D + return(result) + } I want to apply the function for every row .... can I use an "apply" function ... tried but not been able to ... e.g. print(rapply(a,playFn)) Please advise. Thanks, S
