[R] delete data row

[Joshua Wiley]

Dear IRD,

One way is to select every row except those where y = y.j and then
assign that to IR.  In my example, which() returns a vector of the row
numbers where the condition evaluated TRUE, then I used `-` to select
not those rows.

IR <- IR[-which(IR$y == y.j), ]

HTH,

Josh
