I have not really used lm before and I was hoping for some help on a

Here is a toy version of the problem I want to solve.

windows permissions
G'day All,
After searching the archive I am no closer to achieving what I want.
I've seen lots of posts that suggest this can be achieved but the
methods used don't work for me. I won't pretend I understand linux or
samba permissions because every time I think I've got it, I turn out to
be wrong. So here goes.
Let's say I have 3 users & 2 groups.
each group has

Weird permission problem
Hi,
When I try to do anything on my samba system a connection is made to IPC$, but this is
mapped to a directory /root/tmp. This seems odd. To make matters worse ordinary users
cannot access this directory, so the only user who can access the IPC$ share (ie, do
anything at all) is the root user.
What have I don wrong. I cannot find any reference to IPC$ being linked to a directory

One way ANOVA with NO model
I'd like to do a simple one-way ANOVA comparing the means of 6
groups. But it seems like the only way to do an ANOVA in R is to
specify some sort of model, where there is an outcome or dependent
variable that is a function of independent variables (linear model).
But I don't have a linear model, I just want to do a simple ANOVA
(and f-test) to compare the means. How do I do

compiling fedora srpm on CentOS
I tried installing fedora grpc srpm on CentOS and ran into following error
when installing srpm. I understand fedora makes use of more recent versions
of openssl, glibc etc but why should this happen when installing source rpm?
Any pointers/articles on how to go about building fedora srpms on CentOS?
Any way out other than building directly using sources?

unable to load shared object
Thanks for asking.
The path where R tries to load the dll from does not exist I think (or
the install process deletes it after the error - might this be the
case?):
C:/Users/wewol/OneDrive/Documents/R/win-library/3.5/grpc/libs/x64/grpc.dll'
When I am checking after the error that path is only valid up to:
C:/Users/wewol/OneDrive/Documents/R/win-library/3.5/
So maybe (?) the install process

Re gression for loop test HELP! URGENT!
Hi everyone!
I'm new to R, and I'm stuck on a problem I don't know how to approach.
I have calculated a regression in the form of M ~ D + O + S, and I would
like to take this regression and test it with other samples, 5 at a time(5
meaning 5 set, each consisting M, D, O, and S of a specific date). I assume
I'll need a for loop. Right now, My data of M, D, O, and S are all stored in

re gression trees: mean square vs. absolute errors
Hi,
I am working with CART regression now to predict a probability; the response
is binary. Could anyone tell me in which cases it is better to use mean
square error for splitting nodes and when mean absolute error should be
preferred.
I am now using the default (MSE) version and I can see that the obtained
optimal tree is very different from the tree with the least mean absolute
error.
Thanks in

Re gression with Intersection Constraint
Hi,
Previously I posted a thread asking help on how to best-fit (in the least
squares sense) a straight line through a set of data points. Thanks a lot to
all replying to it. I managed it in Matlab using a function 'fit_3D_data'
(link:

Re gression for levels of a factor/xyplot type="r"
Hi,
I'm sure these are basic problems so I apologise in advance for my
ignorance. I have a dataset with X, Y, and a Factor with 4 levels. I am
trying to figure out how to use lm() to find the r2 value, slope and
intercept of an X~Y regression, for each level of the Factor. Is there a
way to do this automatically without having to specify different subsets of
the factor?
my code so far:

re gression with multiple dependent variables?
i have a series of regressions i need to run where everything is the same
except for the dependent variable, e.g.:
lm(y1 ~ x1+x2+x3+x4+x5, data=data)
lm(y2 ~ x1+x2+x3+x4+x5, data=data)
lm(y3 ~ x1+x2+x3+x4+x5, data=data)
is it possible to run all these regs with a single command? given that the
bulk of the work for linear regressions is inverting a matrix that depends
only on the independent

Universal Groups and Domain Local Groups for a given user?
Does samba returns the universal groups for the user using wbinfo or
some other command?
Does samba rettun the domain local group assigned to user for trusted
domain?
Suppose we have a forest with two domains A and B. Doamin B has a domain
local group of 'grpB'. Domain A has a user called 'user1' and it is a
member of "DomainB/grpB". Does samba return the above group

glusterd2 problem
Hi Dmitry,
How many nodes does the cluster have ?
If the quorum is lost (majority of nodes are down), additional recovery
steps are necessary to bring it back up:
