all.equal() will give some details on the differences between your objects.
If you don't care that some attribute will differ, either ignore all.equal's
output concerning it or remove it before giving the object to all.equal.
E.g., if you don't care about dimnames but do care about dimensions do
It might be a C code wrapped around.

Hi ,
I want to apply the following code fo my data with 400 predictors.
I was wondering if there ia an alternative way instead of typing 400 predictors
for the following code.
I really appreciate your help.

fit.final- lm(Y~X1+X2+X3+.+X400, data=mydata) ???
Hi List,
I have used XML in R version 2.9.2. The code is working fine using Rv2.9.2

names(dat1)[1]-Y

I think that what you are looking for is:
all.equal(tm,tmm,check.attributes=FALSE)
But BEWARE:
m - matrix(1:36,4,9)
mm - matrix(1:36,12,3)
all.equal(m,mm,check.attributes=FALSE)
gives TRUE!!! I.e. sometimes attributes really are vital characteristics.
cheers,
Probably you just want
Y ~ .
where . means everything which doesn't appear elsewhere in the formula.

HI,
You could try these:
tmp1-list(a=1,b=NA,c=3,d=NA)
lapply(tmp1,function(x) if(is.na(x)) NULL else x) #changing NA to NULL
#$a
#[1] 1
#
#$b
#NULL
#
#$c
#[1] 3
#
#$d
#NULL
#other case;
tmp2-list(a=1,b=3,c=4,d=5) #want to change list elements a, c to NULL
tmp3-lapply(tmp2,function(x)
Always look at the help page. If you type, in this case, ?scatterplot, you'll
see that all you need to add is the argument smooth=FALSE to omit the loess
line.

Thanks for all of these useful answers.
Thanks also to Ben Bolker, who told me offline that c() is a general
way to access the main part of an object (not tested).
I also tried:
identical(matrix(tm), matrix(tmm))
[1] TRUE
which also works, but does _not_ solve the problem Rolf warns about
