Split a data.frame
...hich row of DF contains
that element, and return DF with all rows starting from next row of the
corresponding element and ending with the preceding value of the next
element.
So in my case, I should see 2 data.frames
1st data-frame with name = 'v' (i.e. 2nd row of DF)
2nd data.frame with number_of_rows as 0 (as there is no row left after 'c')
Similarly if split_str = c('v'') then, my 2 data.frames will be
1st data.frame with name = 'a'
2nd data.frame with name = 'c'
Any idea how to efficiently implement above scheme would be highly
appreciated. I tried with...

R/S Difference - split
In S it is possible to "split" a matrix into its rows, using
split(matrix, 1:number_of_rows). This is not possible in R.
Example:
R:
R> split(matrix(rnorm(1:20),4, 5), 1:4)
Error in split(x, as.factor(f)) : argument lengths differ
S:
> split(matrix(rnorm(1:20),4, 5), 1:4)

troubles reading a text file
Dear R experts,
For quite some time I have been trying to solve a mistery of reading a seemingly trouble-free text file. The data is temperature reconstruction arranged as a huge grid, preceded by seven "header lines" (which you see better if file is opened in Firefox or Chrome).
This is the data (gridded temperature reconstruction)
