A consulting client has a large data set with a binary response
(negative) and two factors (ctry and member) which have many levels, but
many occur with very small frequencies. It is far too sparse with a model
like
glm(negative ~ ctry+member, family=binomial).
I have no idea. A data set that generates the error would be very helpful to
me. What is the role of the last line BTW, the one with 1% on it?
Looking at the code I would guess that the vector tied has an NA in it,
but
how that would happen I can't see. There is a reasonable chance that
Hi
May I ask you why do you need such operation. I cannot imagine a situation
where I would need to do this. The only imaginable procedure is to merge NA
enhanced object with another object but for that situation usually
?merge
is used

I'm looking to find a way to trace back the original variable name after a
being passed through a series of functions.
I can get the variables names for the current call easy enough with match.call,
but I'd like to go back further if the function was called from another
function.
Say I have.

Dear R-help list,
I have a problem in which I would like to concatenate elements from lists in
a combinational order. For example, I have a list of n character vectors
(here 3), each with m elements (here 7,3,1):
lst - list(c(a,aB,aBC,aC,B,BC,C), c(B,Bc,c), c(D))
[[1]]
[1] a aB aBC aC B

lst - list(c(a,aB,aBC,aC,B,BC,C), c(B,Bc,c), c(D))
How could I create an exhaustive list of length 21 now, each of whose
elements
contains a unique combination of vector elements?
Hi Evelyne,
Not really easy, as you have to work out the upper (55) and lower (47.27)
latitudes of Germany, but try this:
DEylim-c(47.27,55)
DENS-diff(DEylim)
clip(5.8,15.1,DEylim[2]-0.494*DENS,DEylim[2])
abline(h=60)
map(worldHires,Germany,fill=TRUE,col=blue)
text(10.3,52.5,CDU/CSU,col=white)
Petr,
The reason I need to do this is that I'm going to be using some large
datasets in WinBUGS, but there is some missing data for the files I'm
using. In order to make the data files readable in WinBUGS there have to be
NAs in place of missing data so I'm trying to add in NAs where there are

Hi,
I don't quite understand the logic since some later assignment will
overwrite the previous one. I simply assign for the current index and
ignore the index after it. In addition, the column Dads.Renamed is not in
the data.frame you defined in the post and I used Father_ID to substitute
for
Hello!
I've built several packages before, but am now building a new package and
would like to have a vignette to go with it. I will be using knitr for it.
My question, please: could someone recommend a good reference on the
content-type material itself for the vignette, please?
Thanks,

If all you want is to add a row of na's could you just do something
like:
nExpectedRows-length(unique(animals)) * length(unique(animalYears)) * 2
newDf-data.frame(animals=rep(NA,nExpectedRows-nrow(comAn)),
animalYears=rep(NA,nExpectedRows-nrow(comAn)),

Hey Tom,
This solution works great, but if I try to then insert it in my function
that I've displayed above and apply it to my split dataframe I get the
error message:
Error in `[.default`(xj, i) : invalid subscript type 'list'
The reason why I need to try and get this to work within the
plot(density(as.numeric(dd)),
axes=FALSE,
xlim=c(as.numeric(as.Date(2014-01-01)),
as.numeric(as.Date(2014-12-30)))
rug(as.numeric(dd))
axis(side=1,
at=seq(from=as.numeric(as.Date('2014-01-01')),
to=as.numeric(as.Date('2014-12-1')),length.out=12),
I have the dates of occurence of a repetitive event. I would like to
plot the density of these events, as well as their specific temporal
location. This is as far as I have gotten:
# generate some sample data: dates in 2014
random.dates - sample(1:31, 100, replace=TRUE)
random.months -
You could change the x component of density's output back into a Date object
and let plot choose a Date axis in its usual way. E.g.,
den - density(as.numeric(dd))
den$x - as.Date(den$x, origin=as.Date(1970-01-01))
plot(den$x, den$y)
(You probably will also want to normalize the y
