I have a 2 column data.frame:
> d[1:5,]
a b
1 80015 C
2 80016 B
3 80023 C
4 80062 B
5 80069 B
I want to apply a function across each row:
> for(i in 1:nrow(d)) {
+ myFun(con, d[i,]$a, d[i,]$b)
+ }
How do I do this using apply()? I'm unsure how to tell apply() to pass
data from columns a and b for a given row as arguments to the function
myFun().
Thanks in advance for any pointers,
Nathan
