Dear R People: Is there a library for Multivariate time series, please? For some reason, I'm thinking that Dr. Paul Gilbert may have one? R Version 1.6.2 (i've updated!) for Windows Thanks so much! Sincerely, Erin Hodgess University of Houston - Downtown mailto: hodgess at uhddx01.dt.uh.edu

Dear R people is there a module for quality control, please? X bar charts, and such? perhaps a contributed package? Thanks in advance!

Dear R People: Here is an interesting question(I think) Suppose I want to calculate Centered Moving Averages; i.e. x[1] <- ( sum(y[1:12]) )/12 x[2] <- ( sum(y[2:13]) )/12 and so on. Of course, this is easily done through loops. However, I have been trying to do this more elegantly, but have failed. I have tried things like j1 <- 1:109 j2 <- 12:120 x[1:109] <- ( sum( y[j1:j2])

Dear R People: I have the source for R version 1.1.1 on a UNIX system alpha-dec-osf4. The ./configure works fine. When I do the make, it works fine until it tries to build the package tcklc. I get an error of Tk_Saf_Init not identified Then it kicks out. Any suggestions, please? Thanks! Sincerely, Erin M.

I have been having the same problem as poster Hodgess, below. It appears that her question was never answered, so I would like to share a solution with the community. The problem is the (apparent?) inability to produce moving range process behavior (a.k.a. "control") charts with individuals data in the package "qcc" (v. 2.0). I have also struggled with the same limitation in

Hello, R People: How do I change the size of a graph, please? I tried par(cin=c(8.5,11)) and it said that Warning message: parameter "cin" can't be set in: par(args) > par(fin=c(8.5,11)) > plot(xa,ya) Error in plot.new() : Figure region too large Also, can I set for portrait or landscape, please?

Dear R People: I'm using the locator() function on a chart and I select two values. Is there a way already in place to connect the two values with a line segment, please? Just thought I'd check before I started coding.

Dear R People: I am using qcc for a quality control class. I have used qcc with type "xbar.one" for individuals but cannot determine how to plot a moving range control chart.

Dear R People: I am drawing graphs for a College Algebra class. I would like to have the x and y axes, along with the lines that I am plotting. So I leave off the axes, and use xlim and ylim. Then I add my abline(v=0). However, I would like to have tick marks on the abline. How would I do that, please? Thanks in advance! Sincerely, Erin M. Hodgess, Ph.D. Associate Professor Department of

Hello R People: Suppose I create a function, x.e, via the fix command: > x.e <- fix(x.e) When I type in x.e, the function code appears, along with the name/number of the environment. However, if I create a function, y.e, and source it in, when I type in y.e, the function code only displays(no environment). Why is this, please? (It's not a bug....I just wondered). I am using

Dear R People: Here is a very simple question, please: I have a data frame with the state name, state division, and population. Note: state division is something like Atlantic, Mountain, etc. I want to produce a table with the state division and the total of the populations for the states within that division. I've been messing with "table" but so far, no luck. This is R1.3.1,

Dear r People I have a bootstrap question, please. (this may possibly be a problem with my understanding of the bootstrap) Suppose I have a sample of size 15, x[1], ...x[15]. This is a sample which is small compared to the population. by the way, the x[i] are iid and have a common distribution F. As I understand the bootstrap, that function will take a user specified number of repititions.
