I have the problem with the basic test too.
But I installed D(COM) for use with the R2wd package.

Hi, dear R users,
I'm running a Tobit regression and using summary to display model results.
It used to work. But this time, I kept getting this:
summary(RES_TOBIT)
Length Class Mode
1 vglm S4
Could anyone tell me how to solve this problem, and why I got this problem?
Thanks.

Thank you again
It is funny how stupid I was
Elrm, clogit {survival} or exactLoglinTest are only exact-like, the truth
is, R don't have it... and glm is poor.

Hello,
I'd like to transpose data to create an analysis-friendly dataframe. See
below for an example, I was unable to use t(x) and I couldn't find a
function with options like PROC TRANSPOSE in SAS.
The ideal solution handles variable quantities of SITE - but beggars can't
be choosers. :-)
Responding to the suggestion by D Winsemius :
s1 - survfit(mod1,newdata=inc[50050:50100,c(strt,stp,incpost,
amt,rate, termfac)],
+ se.fit=F,individual=T,type=aa)

Hi Mike
reshape will be your friend.
reshape(RAW,direction=wide,timevar=SITE,idvar=USER_ID)
there is also the 'reshape'-package, which can do some more
sophisticated transformations.

Thank you, Peter, and also David and William. The las argument indeed
