I have the following problem :

14700, 15340, 15948)
yy <- c( 267, 275, 281, 287, 296, 306, 316, 325, 334, 351, 365, 377,

Indeed, the instructions at CRAN work (with the small addition that one
needs to be a superuser to edit the software sources). The confusion
arose because the c2d4u PPA is the main search result when googling
"upgrade R 3.0.1 ubuntu".

I am not aware of an implementation of the algorithm you
describe. If you are not locked to that particular approach,
function diana() in package cluster performs polythetic,
hierarchical partitioning which could be used to get your
starting cluster centers.

Hi Ron,
It looks like the data you want is generated by javascript; if so

Jeff, Andrew,
When you come up with a solution to the upgrade problem, please send it to me.
I have a similiar problem under Mint, which is an Unbuntu fork.
Thank you,

I am trying to upgrade to R 3.0.1, and I am working on ubuntu.
Apparently, the new version is available in the following ppa:

to my software sources.
I then run the typical sudo apt-get update && sudo apt-get dist-upgrade,

Read the help file on 'plot' and look at some of the examples to see
how to place labels in various places on a plot. This is not
difficult if you have read any of the documentation.

Hi,
If you have a vector of values to compare:
thresh1<- c(30,4,12,65,5)
indx<-findInterval(thresh1-1,cumsum(X))
indx2<-ave(rep(indx,indx),rep(indx,indx),FUN=seq)
X[indx2]
# [1] 1 3 4 5 8 1 1 3 4 1 3 4 5 8 15 1 3
#you can split this into a list
split(X[indx2],cumsum(c(TRUE,diff(
Dear Brad,
It's impossible to know from the information given whether the model is
identified or not. Including a reproducible example of your problem, as the
r-help posting guide asks, is a good idea.
Assuming that OCB is an observed variable, however, the model is identified,
but implausible. T

Dear R users:
I am trying to run a path analysis using sem package in R. But I have

Thanks for that. Still I am a bit confused. Please advice me.
Now, I have got minimal adequate model keeping all the those significant

Hi,
I know that with readlines you can start executing a code upon user input.
What I would like to do is to have the ability to abort a code based on a
new user input. E.g. when the user hits enter the code stops running. That
is, I would periodically check for a user input and stop the code when

Since you have lost the original values, one part of the case study will
not apply: the use of Mean().
