Hi everyone,
I've relatively new to R, and i'm trying to use it to perform a Principal
Components analysis (PCA)
I've done this using WEKA previously, and now i'm trying to do so using R's
prcomp and princomp (both options would work for me).
One problem i've found is that while WEKA PCA allows u
Dear gurus,
Im a newbie, and I want to ask a very general question.
Assume that I have a set of numbers as follows,
1, 1, 2, 10, 100, 10,1
>From these, I need to identify which number is the most different as
compared to others. (in this case, it will be 100, since its way larger
than the other

Hi, thank you very much for the advice. I'll try it out, and see where I
can take it from there.
@david, your point is noted. I will avoid such mails in the future.

Dear all,
I'm an Sri Lankan undergraduate student. I'm also a total newbie to R.
My aim is to use the poLCA package to do a latent class analysis.
I found the documentation very helpful, but need to make a small
clarification that has stumped me awhile.
In my work, I need to make provision for c
Hi everyone,
I'm an R newbie working with the poLCA module. I achieved my target without
having to bother anyone, but It seems that I've got stuck at the last
minute.
My problem is simple. I need to write my results into a file.
My results are in the shape of a list (unbalanced columns)
I've cons
Hi,
Thank you very much for sharing these ideas. I really appreciate them. Let
me go try them out :-)

Hi everyone,
I'm using the poLCA module for some analysis work.
Basically, Im using the command >poLCA(f, data=response,nclass=2)
This returns a poLCA object (a list)

below.
[[5]]

Hi,
many thanks for the reply. I really appreciate it.
Since I'm still very new to R, I think I should take some time to research
what you suggested.
(I don't want to keep posting basic questions to the list all the time)
But still, thank you so much for being helpful...

Hi everyone / poLCA gurus,
I'm facing a problem regarding conditional dependence and poLCA.
Using a few data sets composed of only 1's and 2's, i'm able to do a latent
class analysis for independent data columns using poLCA.
The commands I use to do this are something like,
bcs = read.csv("data.
