[R] Read a dataset with different lengths

[Xiyan Lon]

Dear useR again,
How can I read a dataset if lines in dataset did not have same
elements (have different lengths), For example:

1    2,  4, 16,  1,  1,  3,  1,  1, 15,  5,  1,  1, 14,  1,  1
2    2, 13,  5,  1,  1,  3,  1,  1, 15,  5,  1,  1, 14,  1,  1
3    4,  5, 11,  1,  1,  6,  1,  1,  5, 14,  1,  1, 15,  1,  1
4    2,  5,  9,  1,  1, 14,  1,  1,  8, 16,  1,  1, 13,  1,  1
5    3,  7, 14,  1,  1, 14,  1,  1,  5, 21,  1,  1,  8,  1,  1
6            6,  3,  1, 12,  1,  1,  5,  8,  1,  1, 15,  1,  1
7            6,  3,  1, 11,  1,  1, 10,  7,  1,  1, 21,  1,  1
8           21, 20,  9,  1,  1,  6,  1,  1, 13, 10,  1,  1,  1
9    5,  7, 21,  1,  1, 13,  1,  1, 14,  2,  1,  1,  6,  1,  1
10   8, 14, 10,  1,  1,  5,  1,  1, 10,  5,  1,  1,  5,  1,  1
11   5, 20, 17,  1,  1, 19,  1,  1, 14,  7,  1,  1,  6,  1,  1
12   7,  4, 11,  1,  1,  2,  1,  1,  5, 13,  1,  1, 14,  1,  1
13   7, 14, 13,  1,  1,  6,  1,  1, 13, 16,  1,  1, 17,  1,  1
14   7, 14,  5,  1,  1,  5,  1,  1,  5, 17,  1,  1, 17,  1,  1
15           3,  9, 12,  1,  1, 18,  1,  1,  6,  1,  4,  1,  1
16   7, 10,  5,  1,  1, 12,  1,  1,  5, 17,  1,  1, 13,  1,  1
17  12,  8, 16,  1,  1,  5,  1,  1,  8, 10,  1,  1, 14,  1,  1
18   5, 11,  7,  1,  1,  5,  1,  1, 18, 13,  1,  1, 17,  1,  1
19   7, 13,  8,  1,  1, 14,  1,  1,  5, 17,  1,  1, 13,  1,  1
20   7, 18, 21,  1,  1, 16,  1,  1,  5, 17,  1,  1, 13,  1,  1

I know that in BioC package rmutil have a function (read.list) to
handle different lengths sets of lines but it did not work.
> library(rmutil)
Error in library(rmutil) : 'rmutil' is not a valid package -- installed < 2.0.0?

Are there any others function to handle this.
