HelloList, Do someone have got a link/document/"How To" for setting up Samba 3.0 in ADS-Enviroment. I read Samba-Collection-How-To, but I got stuck and need help. My favour will be a easy and perspicuous manual like a walkthrough Thanks in advance. Regards Dominik Brosch

...t; Note the doubled brackets. So seems pretty explicit to me. Well, yes. Once it's pointed out it's "obvious". But it's buried pretty deeply in a large mass of text, and I didn't see it until you pointed it out. If *I* had written the help file, it would be much more perspicuous. cheers, Rolf -- Technical Editor ANZJS Department of Statistics University of Auckland Phone: +64-9-373-7599 ext. 88276

Hi all, I'm analyzing micro array data.. it has produced a file (to be specific matrix) withdimension of 35556 2. first few lines of the matrix are as below.. probe_name control.fdr.pvals.present 10338001 0.000440001 10338002 0.000583093 10338003 0.000528449 10338004 0.000610362 10338005 0.000151825 10338006 0.0001733 10338007 0.000152924 Now, i want only rows whose

I'm sure I've read about the difference between a[[i]] and a[i] in R, but I cannot recall what I read. Even more disturbing is the fact that I don't know how to search the newsgroup for this. All the different combinations I tried were declared not to be valid search syntax. 1. What sort of object can the operators [] and [[]] be applied to? How do they differ? I mean objects in

...p until the penny drops. This keeps happening to me, over and over again (with sufficiently long intervals between occurrences so that my ageing memory forgets the previous occurrence). Is there any way to trap/detect the use of an optional argument called "X" and thereby issue a more perspicuous error message? This would be helpful to those users who, like myself, are bears of very little brain. Failing that (it does look impossible) might it not be a good idea to add a warning to the help for lapply(), to the effect that if FUN has an optional argument named "X" then pas...

For a given linear regression, I wish to find the 2-tailed t-dist probability that Y-hat <= newly observed values. I generate prediction intervals in predict() for plotting, but when I calculate my t-dist probabilities, they don't agree. I have researched the issues with variance of individual predictions and been advised to use the variance formula below (in the code). I presume my
