I believe you have received advice on how
to solve your problem already, this is just
to say why your 'sapply' call failed.
Your call to 'sapply' assumes that there is
a 'bt_m' argument to the function, which there
isn't. Another problem might be that there
is an 'alp' argument but that is not given
in the 'sapply' call.

Hi,
I have this code here and try to use sapply code. But I got error message that
I don't really understand to correct.
bt<- c(24.96874, 19.67861, 23.51001, 19.86868); round(bt,2)
alp<- c(2.724234, 3.914649, 3.229146, 3.120719); round(alp,2)
bt_alp<- data.frame(bt,alp)
sapply(bt_alp, function(bt,alp) ((bt_m/bt)^alp), bt_m = min(bt))
sapply(bt_alp, function(bt,alp) ((bt_m/bt)^alp), bt_m = min(bt))
Error in FUN(X[[1L]], ...) : unused argument(s) (bt_m = 19.67861)
Thank you for any help given.
