I have a large (rectangular) vector of strings, e.g:

```
my.strings <- c("1234567", "1234567", "1234567", "1234567")

```

which I would like to convert to a matrix:

```
#      [,1] [,2] [,3] [,4] [,5] [,6] [,7]
# [1,]    1    2    3    4    5    6    7
# [2,]    1    2    3    4    5    6    7
# [3,]    1    2    3    4    5    6    7
# [4,]    1    2    3    4    5    6    7

```

Is there a simple way to do this in R? (Unfortunately, yes the strings of numbers are indeed character strings and not numeric.)
