How to parse the arguments from a function call and evaluate them in a dataframe?
Hi,
I would like to write a function which has the following syntax:
myfn <- function(formula, ftime, fstatus, data) {
# step 1: obtain terms in `formula' from dataframe `data'
# step 2: obtain ftime from `data'
# step 3: obtain fstatus from `data'
# step 4: do model estimation

}

Plotting question re. cuminc
Hello everyone,
(This is my second question posted today on the R list).
I am carrying out a competing risks analysis using the cuminc function...this takes the form:
cuminc(ftime,fstatus,group)
In my study, fstatus has 3 different causes of failure (1,2,3) there are also censored cases (0). "group" has two levels (0 and 1).
I therefore have 6 different cumulative incidence curves:
cause 1, group=0; cause 1 group=1
cause 2, group=0; cause 2 group=1
cause 3, gro...

Problem with opusfile & ndk
...or android with
*ndk-build*.
In particular, with arm64-v8a platform: Google removed <sys/timeb.h> from
android.
And now building opusfile with nkd-build crashes with error "fatal error:
'sys/timeb.h' file not found".
Can you help me? What can i replace *struct timeb* and *ftime function* ?
Thank you.

We have the functionality... I thought we wired -ftime-report up to it? If
that doesn't work I'll have to go digging.

numerics from a factor
...(Surv(1:6 /2) ~ 1)
> fit$time
[1] NA 1 NA 2 NA 3
A year or two ago some test cases that broke survfit were presented to me. The heart of
the problem was numbers that were almost identical, where table(x) and unique(x) gave
different counts of distinct values.
The solution was to use "ftime <- factor(time)" at the top of the code, and do all the
calulations using the integer levels of the factor as the unique time points. At the very
end the numeric component "time" of the result is created using
as.numeric(levels(ftime)). It's this last line that breaks.

I just checked -- it produces a flat report -- it would be nice to
produce something similar to -debug-pass=Structure outputs.

Wishlist: xtabs and table to optionally use attribute value labels (PR#8659)
...last table in the example output by a
statement like 'table(data1$time)' or 'table(data1$time, use.value.labels=T)' or
'table(as.factor(data1$time))'.
'table(as.factor(data1$time))' would do the job, if 'as.factor()' would use
value labels (like in
data1$ftime <- factor(data1$time,levels=attr(data1$time, "value.labels"),
labels=names(attr(data1$time,"value.labels")))
), whenever they are present. This might also help in obtaining more meaningful
output e.g. from regression procedures with such data.

Those numbers are purely speculative -- does Clang has an option to
