[R] resclaing/resampling data

[Jan M. Wiener]

hello,
I am trying to rescale a matrix according to one column in the matrix.
Imagine having two matrices with 2 columns each:

mat1:
1    2.1  
2    2.2
3   2.2
4   2.4
5     2.7
6   2.9

mat2:
1    1.9  
2    2.0
3   2.1
4   2.2
5     2.4
6   3.0
7.  2.8

I now want to rescale mat2 such that the values in columns 1 are also
between 1 and 6 (as in mat1). Of, course the values in column 2 should
be rescaled accordingly (simple interpolation).
Are there any predefined functions in R that does such rescaling?
Thanks for any answers,
Jan
