[R] Creation of a new data frame

Dear all,

I have a data frame of 18556 rows and 19 columns and wish to create a new grid from these data of dimensions 360 rows and 720 columns.

The existing data frame is set up so that every 38 rows makes up one row of the new data frame, with 2 NA values at the end of each 'block' that should be removed before being inserted into the new grid.

So to be clear, row 1 of the new data frame consists of rows 1:38 of the existing data frame, with the 2 NA values on the end removed. Row 2 is 39:77 and so on.

How do I go about creating this new 360 x 720 grid from existing data?

Many thanks,
