Hello,
I have data with workers within departments. I am interested in testing the
effects of peers' satisfaction on employees' productivity. To assess peer
satisfaction, I calculate, for each employee, the average satisfaction of
the employees' peers within the department. In other words, I calcu
Thanks Rui,
Depending on how I try to install I get a different error. I am
starting to think that somehow the Ubuntu installation may be faulty.
I used a ISO that I had burned about a year ago. I had no problem
then with a shared installation but who knows.
sudo apt-get update
sudo apt-get insta
Hello,
I am trying to run a *multilevel moderated mediation model in R*, with data
nested in three levels (children, within classes, within schools). All of
my variables are at the individual level, but I still need to account for
the nested nature of the data.
In separate analyses of mediation

Try using time series objects in xts. Should be easy. At worst once the xts
object is automatically arranged by date you have to note the row numbers for
each year period and I think data would be ok to handle unless it is more than
30-40 years when you would look up other xts options. Xts objec

I have a data frame in which the first column is a sequence of monthly

but with annual values instead of monthly, created by summing the months

Cancel my mailing that source.list. to r-sig-debian.
I took one last look at the sources.list file and realised that I had the same
repository repeated. I had read it as being commented out but it was not.
Delete one line and I was fine.
Nothing like blindness! I must have scanned that thing
Will do. Thanks.

Thanks Ista,

I think I have a faulty Ubuntu installation and will have to reinstall. What fun

Hi John,
The official instructions at
https://cran.r-project.org/bin/linux/ubuntu/ work on a fresh

the configuration of your local system rather than with any problem
with either R or ubuntu. My guess is that you've been reading
Hello,
I never installed R on Ubuntu like you did it.
I follow this:
sudo apt-get update
sudo apt-get install r-base
sudo apt-get install r-base-dev
And it works at the first try. See [1]
The problems I [always] have are with missing Ubuntu libs needed by
contributed packages, not with base R

Hi John,
Is the subject line of your question correct? Ubuntu 10.04?
If that is not a typo, that could be contributing to your problem. I
believe that the current stable release of Ubuntu is 18.04.
According to the following link ubuntu 10.04 was released almost 10 years
ago and was "retired" about
