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.

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

Hello, Although your message is not very explicit about the structure of your data frame, I think you can get what you want by using a combination of the function "split" and the "apply" functions family: apply, lapply and sapply. If you provide a more detailed organization of your data frame, perhaps we can give to you a more wiser advice. Thanks, Carlos. P.S: By the way,

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 would like to superimpose a normal curve on a histogram. I've seen this example in a book, somewhere. I know that you draw the hist, get the mean and sd of the data set, but then I'm stuck. Could you help, please? Thanks!

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
