[R] create sequences from two "from" and "to" vectors

[Greg Snow]

Try:

> mapply( seq, from=1:4, to=7:10 )
     [,1] [,2] [,3] [,4]
[1,]    1    2    3    4
[2,]    2    3    4    5
[3,]    3    4    5    6
[4,]    4    5    6    7
[5,]    5    6    7    8
[6,]    6    7    8    9
[7,]    7    8    9   10

Is that what you want?
