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.
