When i am running a *DELETE * query on MS SQL database I am getting
*[RODBC] ERROR: Could not SQLExecDirect * error. I am getting this error for
the DELETE query that requires more time.
Please suggest workarounds if any.
Thanks

Dear Members,
I have a dataset that is similar to the first example in the car function, cts
package
data(V22174)
fit - car(V22174,scale=0.2,order=7, ctrl=car_control(trace=TRUE))
summary(fit)
I would like to ask if there is a way to get the predicted/fitted values for
all the timepoints
Hi Tom,
I think you are going to get better answers if you include some code which
helps reproducing what you are doing for other users (posting guide). Exporting
regression outputs to Excel does not seem to be the way to go. Aren't you just
looking for ?predict. I am sure R can do the job for

I have a question about combining effect sizes generated by escalc in metafor.
I realise these may be stupid things to do; but they are deliberately so to
explain what I mean - I don't intend doing this!
I have 3 studies; each of which has a different measure of effect/presents the
Hi. I am running the code below. I am getting the error
Error in match.names(clabs, names(xi)) :

I don't really want to specify the size of the allFuku data frame at the
beginning but even when I tried it I still got this error.

Oggetto: Re: [R] problem of tapply function
The argument to tapply is FUN, not fun. R is case sensitive.
Not sure why but when I change this:
temp.df[,month]-month
temp.df[,year]-year
to this:
temp.df[,2]-month
temp.df[,1]-year
it seems to work.

This is definitely not an error, all these behaviours are by design. You need
to (re)read the description of factors in the Introduction to R document that
comes with the software. Factors are not optimized versions of strings, they
are finite sets of category information designed for use in

Hi
I have a problem with linear regression. This is my codes:
acc1- lm(data$acc ~ dummy + data$Reqloanamount + data$Code + data$Code.1 +
data$EmpNetMonthlyPay + data$Customer_Age + data$RTI)
summary(acc1)
These attributes are all numerical except the acc(factors), so how can I
fix the problem R
Please provide some data from your variable data.
Show the output of dput( data) or an subset
of data which leads toe the specific error.

1. Post in plain text, not HTML.
2. Read ?lm and note the data argument. Use it in your lm call instead
of all the $data extractions.
3. Your problem is with the summary() call, so read ?summary.lm. Learn

I suspect the problem may be with the structure of the data.

Ted:
Yes. You're probably right, and I'm probably wrong. I did not read
carefully enough. Impossible to know for sure with such an ill-posed
query, though.

I am not able to find the criterion under which the best subset model for a
certain size is chosen for the function regsubsets (leaps package in R) . For
leaps function, we can determine the method ( cp,r2 or adj r2). For example,
x - predictors
y - response
g - regsubsets(x,y,nvmax=1,nbest=1)
Hi Atem,
Try this:
I created 3 folders (Precip, Tmax, Tmin) within the folder sample

Mohammed:
I am sorry to burst your bubble, but the whole concept of finding a
best subset regression is now considered to be badly flawed. There
will typically be many essentially equivalent choices. Shrinkage of
varying kinds and ensemble fits are the sorts of things that are
done nowadays. I
Dear Sir,
I am not sure about the precision of the cov.wt function. It seems that it
provides different results when using frequency weights. This discrepancy only
occurs with the covariance matrix, not with the correlation matrix.
Do you know to how to solve this issue? Thank you
