Dear R users,
I need to generate random integer(s) in a range (say that beetween 1 to

Any help is deeply appreciated.

Thanks Bill,
Yes in my data too I get some different posteriors also. I guess what I was
getting at was that when I'm dealing with multi-elemental data with 16

was expecting. I'm a student, so perhaps I don't have quite the

If you try

You will see there are very many posterior probabilities there, too, which
differe from 1 by round-off error at most. So your data are not unique.
I don't get why you don't get it.

Hi all,
I was wondering if anyone was able to explain to me why when I run
predict.lda() on some new data I get lots of posterior probabilities = 1.
This seems markedly unrealistic. What do the posteriors mean in the context
of the predict.lda() function?
Thanks

Hi,
I have a line such as:
myline <- "0.10 1.5000 0.6000 538
0.369404"
and I would like to put the numbers into a vector. Some combination of
tabs and spaces occur between the numbers.
I tried:
try1 <- strsplit(myline,"[[:blank:]]+")
> try1
[[1]]
[1] ""
You can use the caret or ipred packages. caret has it setup for
specific models and can be used with parallel processing. ipred can do
loo for any model since you manually code the model.

Hi,
If you have a look at the help for par (type ?par at the prompt) and
then have a read of the section on 'cex' that should point you in the
right direction. You can pass the cex argument to the plot routines as
well rather than changing them in par.
