I want to insert row which is "NA" in 10th row
Try this:
d<- data.frame(x = 101:118, y = rnorm(18))
d2<- data.frame(
rbind(head(d, 9), NA, tail(d, -9)),
row.names = NULL)
That threw an error for me.
Error in do.call(f, cal0) : second argument must be a list
??
Works fine for me on Windows Vista, bot 32/64-bit.
Also works for one-column dataframes.

What about this?
d[ c( 1:9, NA, 10:NROW(d) ), ]
I do not like this behavior of "[" but I suppose it is useful sometimes.
