I have a problem I cannot get over for a long time. Imagine I have a data frame with 17 colums. 16 of them are craniometric variables of Cervus elaphus and one contains age.
The data frame has 83 rows.
I want to write a loop which plots the values of each craniometric variable against the age. The names of columns are V1, V2, V3, etc... What I have done till now was writing this:

layout(matrix(1:16,4,4))
plot(V1~AGE)
plot(V2~AGE)
.
.
.
.

etc.
How to assign a string in the loop so that the program understands it is an object?
Thank for your help in advance.

Michael
