I had an NA in one row of my data frame, so I called na.omit(). But I do not understand where that row disappeared to.
>fri=na.omit(fri) > fri Date.Only DAY Hour Min15 Quarter Arrival.Val Arrival4 1 09/05/2008 Friday 8 33 3 32 8 2 10/24/2008 Friday 21 86 4 28 7 3 10/31/2008 Friday 8 33 4 20 5 4 10/31/2008 Friday 8 34 4 20 5 5 10/31/2008 Friday 8 35 4 12 3 .... 1233 08/28/2009 Friday 0 2 3 12 3 1234 09/18/2009 Friday 22 92 3 8 2 1235 09/18/2009 Friday 23 93 3 20 5 > fri[1235,] Date.Only DAY Hour Min15 Quarter Arrival.Val Arrival4 NA <NA> <NA> NA NA NA NA NA > fri[1234,] Date.Only DAY Hour Min15 Quarter Arrival.Val Arrival4 1235 09/18/2009 Friday 23 93 3 20 5 So, the index numbers of the rows do not seem to have been updated. They are not part of my data frame (I think), so why didn't the rows renumber themselves?
