Constructing a list using a function...
Hello,
Try
myfun2 <- function(DF, FUN){
x <- lapply(as.data.frame(t(DF[-1])), function(x) FUN(x[1], x[2]))
names(x) <- levels(DF[[1]])[ DF[[1]] ]
x
}
myfun2(myframe, myfun)
Hope this helps,

Hi All
I have a dataframe:
myframe<-data.frame(ID=c("first","second"),x=c(1,2),y=c(3,4))
And I have a function myfun:
myfun<-function(x,y) x+y
I would like to write a function myfun2 that takes myframe and myfun
as parameters and returns a list as below:
mylist
$first
[1] 4
$second
[2] 6
Could you please help me with this? Doesn't seem like the "apply"
family of functions were intended for this case.
