Hello Jonathan,
You can use eval() and parse(), although there may be better ways of
getting to your end goal (assuming you have not inherited a series of
character strings held in objects that should be run as commands). At

Sincere apologies and many thanks. The pasted code from the help forum has the
error and I did not see it. When I wrote my own import I used c as I should.

after correcting the error spotted by Thomas, I tried again and it goes to
work, but there is no result after 1 hour.
is there anything I can do to debug?
the dataset has 12mln rows and SAS on a server will produce results in 15
secs. I am running this on PC with XP (hence mem limit of 2.5 gigs)

There is no package called `integrate', but there is a function called
`adaptIntegrate' in the cubature package.

Where is %in% documented within R? I'm pretty sure it's a different
action to ?%in%, and it's not mentioned in ?formula
You find the documentation for operators like -, %in%, if, etc by putting
the operators between
qoutes
?%in%

?if

Hi, Dear Community,
My data set logit.pred contains 2 columns and 1400 rows. When I want to use
the first column, it is very strange. Where the $ come out? Thanks so much!

head(logit.pred)

The str function would have given you a better one-shot look at
logit.pred.

Dear R-list members,
I would like to pose a question about the use and results
of the glm() function for logistic regression calculations.
The question is based on an example provided on p. 229
in P. Dalgaard, Introductory Statistics with R, 2nd. edition,
Springer, 2008. By means of this
