No. You are mistaken. Assuming that V0 is defined and has the same
length as
there are rows in that data.frame, then V1 and V2 would be the
arguments in
the formula and they would not be quoted.
?glm # and work through the examples
With the example I meant that the factors in the vector V1 and V2
would be treated like individual binary/dummy variables.
They would have been with the call I offered. I get the sense that the
best advice might be to consult a local statistician.
Back to my real question; Is there no other way to do this in R???
"Do this"? You have offered no workable example and only the vaguest
of descriptions of the task.

Hi, sorry my question was not really clear
|Are you very early in efforts at learning R?
No, have been a long term user of R, but only use R for the
statistical
stuff.
The heart of the issue is that I have list of keywords that I want
to
analyse with a machine learning algorithm (20 000 keywords with a
response variables). It's much like "micro" array data, but in my
case
it's not "genes", but instead keywords. To get it to work in R, I
could create a data frame with multiple vectors containing different
factors.
That would look like this
V1, V2,
"Harry", "Kline"
"Brown", "Larry"
If I am not mistaken if I used V1 and V2 with the standard GLM
function the result would be like
glm( V0 ~ "HARRY" + "KLINE" + "Brown" + "Larry")
No. You are mistaken. Assuming that V0 is defined and has the same
length as
there are rows in that data.frame, then V1 and V2 would be the
arguments in
the formula and they would not be quoted.
?glm # and work through the examples
Or I could create a complex ordered array where keywords are
represented 1 and 0.
If I used that in GLM I would get the same result with glm?
But is there a better approach?
