[R] glm with multiple vars

[dirknbr]

I am looping through various models with different combinations of
independent variables which are stored as columns in x

glm(y ~ ??, data=x)

How can I pass the colnames of the selected columns of x into ?? seperating
them with a +

ie I want to generate

glm(y ~ x1 + x2, data=x)
glm(y ~ x2 + x3, data=x)
glm(y ~ x1 + x2  + x4, data=x)
...

I have tried the sedit function (sedit(colnames(current),' ',' + ')) but glm
doesn't understand the output.

Dirk
