I don't see much in the way of an ability to write reports in R the way you

Thanks David!
I see that I didn't produce the correct answer, but perhaps I'm
being thanked for something that was generalizable in that direction.
Better would have ben one of these:
plot(1, ylab= bquote(italic(P) *.(b)*,*~A) )
David, yes, I now see how it worked.
Thanks again,
John

Hi,
I am neither a statistician nor a user of R. I am a programmer trying to
provide my users (both statisticians and R users) data in a format that
works best for them.
What is a data frame? Is source data easier to work with in this format or
a csv file? Or yet another format?
Thanks
I have been trying to simulate from a time series with trend but I don't see
how to include the trend in the arima.sim() call. The following code
illustrates the problem:
# Begin demonstration program
x - c(0.168766559, 0.186874000, 0.156710548, 0.151809531, 0.144638812,

Dear Sir or Madam,
I am trying to explore the citation bias by perfroming meta-analysis. I need to
plot a forest plot on some other proportions other than the usual effect size
OR,RR, RD.
I still do not have any idea after searching google and reading relevant books.
Can anyone kindly
Good afternoon,
Hope you all have a wonderful day. I am glad to be here. Hope you could
help me with the following errors that i have been trying to figure it all
out since last week.
I am using Splus from Insightful, and as i read, R and Splus are very
similar. So hope you could help me.
I don't think I understand what the problem is... The code that you
provided works just fine without the for loop statement. as for the
can't access... The example that you provided doesn't address this.
Unless I am totally misunderstanding. R is an interpreted language
not compiled. Please,
Do not post such questions to this list.
Read an Introduction to R first, please.

Min,
For S+-specific questions the S-news mailing list
would be better.

Unlike R, S+ stores its data objects in files, one file
per object. The ___nonfi (___nonfiles) file contains
a mapping for object names to file names, for those
objects whose names cannot be

It sounds like they would be the best ones to ask then.
What is a data frame? Is source data
Please let me know if this is or is not the right place to ask these
types of questions.
Warning: I am new to R by two days.
I have a simple dataset.
I have loaded the dataset successfully using the following code:
Filepath=(C:\temp\\pilot\dataset1.txt)
Pilot=read.table(filepath, header=TRUE)
Hello List Folks. I¹m trying to do manova using a function which assembles
the response (LHS) and factors (RHS) from different sources. When I do so,
the model routines complain that I'm passing a list for the RHS when I don't
think I am.
Here's a toy example:
r - matrix(rnorm(30), ncol = 3) #
Ken -
Try
aggregate(Pilot$Count,list(Date=Pilot$Date,illness=Pilot$illness),sum)
If you don't want to keep typing Pilot, use
with(Pilot,aggregate(Count,list(Date=Date,illness=illness),sum))
Notice that the aggregated variable will be called x in the output
data frame from aggregate.
