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 functio
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)),
animal
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
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
Cheers

Why should he? seq_len() is part of base R.

Hi Curtis,
Maybe you forgot to tell us how the function seq_len is defined.

This is a bug in the unmentioned VGAM package and you have to report it
to its maintainer (hence CCing Thomas Yee).

Hello,
I believe that the answer to your final question is yes but you are
making a really big confusion of what you want, of how you are
explaining it and of the way R works.
First, I have written a function to read the data from the post, without
creating a disk file. In order to be comple

Hello,
There's nothing wrong with having 'thisCol' and 'thatCol' already defined or
not.
The problem is that your function does NOT return a value. Get rid of the
assignment and it will work.

finalTable[, thatCol])}

Hello all,
Can someone tell me why the following mixture of two log-normal

function works almost always, but for certain combinations (like the
one below), it does not.

I believe this might do what you want a bit faster. I replaced the
while loop with something that is likely to be faster. I saw no
reason for the rounding you were doing, better to use as.integer at
the end.
test <- function(t){
x <- rexp(t,0.1)
while(sum(x) <= t) {
x <- c(x, rexp(
Hi I believe this should provide an example of the confusing behavior.
Run this with t=100 for example:
test=function(t){
x=c()
while(sum(x)<=t){
###I simply generate some numbers from an
exponential until the sum of these numbers gets
to 100(without loss of generality)
x=c(x,round(rexp(1,0.1)
Berwin appears to be correct here. After you do x <- x / 0.0001,
I inserted a call to round(x) - x, and received
round(x) - x

This is basically a case of FAQ 7.31.

We need a reproducible example of this to tell you what is going on.
Find a small example that exhibits the confusing behavior, and share it
with the list.

Thanks for your time and help,
Yes, as the posting guide says, we would probably need a reproducible
self-contained example. Emphasis on "reproducible" and "self-contained.
