[LLVMdev] atomic memoperand patch
Just noticed that when we generate a custom lowering for some atomics
that we forgot to transfer the MemOperand to the new instruction that
touches memory.

OK, Let's try this again! Here is the reproducible script; it is long because I had to copy the panel dataset here. My question is related to systemfit; I don't know how to get the result for the entire panel.

Sadly you failed to set your email program to send plain text and the data is corrupted at my end.
I also think you need to reduce the size of the data set... the intent here is to increase your understanding, not debug your particular analysis.
I will say that I am having a very challenging time understanding what you are trying to accomplish though. What are the equations that you think need

Probabilities from survfit.coxph:
Hello:
In the example below (or for a censored data) using survfit.coxph, can
anyone point me to a link or a pdf as to how the probabilities appearing in
bold under "summary(pred$surv)" are calculated? Do these represent
acumulative probability distribution in time (not including censored time)?
Thanks very much,
parmee

... and the mailing list is picky about attachments... whatever you attached did not conform to the stringent requirements mentioned in the Posting Guide. Pasting the code right into the email is usually safest, though you DO have to post using plain text (as the Posting Guide indicates) or your code may get mangled by the automatic html format removal.

Unless there is good reason not to, always cc the list -- there are lots of
smarter folks than I on it who can help.
I may or may not have time to look at this. Hopefully someone else will.

simple save question
Hi,
When I run the survfit function, I want to get the restricted mean
value and the standard error also. I found out using the "print"
function to do so, as shown below,
print(km.fit,print.rmean=TRUE)
Call: survfit(formula = Surv(diff, status) ~ 1, type = "kaplan-meier")

multi-class classification using rpart
Hi,
I am trying to make a multi-class classification tree by using rpart.
I used MASS package'd data: fgl to test and it works well.
However, when I used my small-sampled data as below, the program seems
to take forever. I am not sure if it is due to slowness or there is
something wrong with my codes or data manipulation.
Please be advised !
The data is described as the output from str()

Is this sapply behaviour normal?
Hi, I'm trying to use sapply to compute the min of several variables, each
of them stored in data.frames, grouped as a list:
Is it normal that mean() and min() produce different objects dimensions?

negative binomial overdispersion question
Hello,
I'm a grad student in the Intelligent Transportation Systems lab at Portland
State Univ. in Portland, OR, USA. I'm trying to learn the basics of R to run a
negative binomial in the near future, and so I ran a test regression on roadway
crash data obtained from "Statistical and Econometric Methods for
Transportation Data Analysis" by Washington et al (p. 250). I ran the

Negative variance with lavaan in a multigroup analysis.
Hi list members,
I saw a couple lavaan posts here so I think I?m sending this to the
correct list.
I am trying to run a multigroup analysis with lavaan in order to
compare behavioural correlations across two populations. I?m following
the method suggested in the paper by Dingemanse et al. (2010) in
Behavioural Ecology.
In one of the groups, lavaan returns negative variance for one path
and I?m
