Dear R People: I have the following time series and plot: > x <- ts(rnorm(50),start=2005,freq=12) > plot(x) > which works fine. I would like to plot a subset of that time series, which I did with: > plot(window(x,2005,2006.83)) Is there a better way to do this, please?

Hello I would like to build R from source and use the PGI compiler, rather than the GCC compiler. I saw the instructions for the Intel compiler in the R Installation Manual, but I didn't see the PGI. I tried a few times without instructions, but without success. Any suggestions would be most welcome. Also, I hope this is the right group for the question. Sincerely, Erin -- Erin

Dear R People: I have generated the following table: > table(zza$DEATH,zza$GENDER) F M 2009-04-21 0 1 2009-04-22 4 2 2009-04-24 6 0 2009-04-25 1 3 2009-04-26 2 0 2009-04-28 3 0 2009-04-29 2 2 However, instead of total counts in the F and M columns, I would like percents. How would I do this, please? thanks, Erin -- Erin

Dear R People: I have a data frame, xm1, which has 12 rows and 4 columns. If I put is xm1[,-4], I get all rows, and columns 1 - 3, which is as it should be. Now, is there a way to use the names of the columns to omit them, please? Thanks so much in advance!

Dear R Gurus: What is the name of the person who has all of the Tcl/tk stuff, please? I know it's James W, but can't remember his last name. I wanted to look at some of his examples.

Dear R People: When I want to produce a small sample confidence interval using t.test, I get the following: > t.test(buzz$var1, conf.level=.98)$conf.int [1] 2.239337 4.260663 attr(,"conf.level") [1] 0.98 How do I keep the attr statement from printing, please? I'm sure it's something really simple. Thanks, Sincerely, Erin -- Erin Hodgess Associate Professor Department

Dear R People: Is there a way to find which objects are functions via ls(), please? I'm sure that there is, but I'm not sure how. Thanks, Erin -- Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences University of Houston - Downtown mailto: erinm.hodgess at gmail.com

Dear R People: Here is a goofy question: I want to extract the zip code from an address and here is my work so far: > add1 results.formatted_address "200 W Rosamond St, Houston, TX 77076, USA" > add1[1][32:36] <NA> <NA> <NA> <NA> <NA> NA NA NA NA NA > str(add1) Named chr "200 W Rosamond St, Houston, TX 77076,

Hello R People: Is there a way to determine if a function exists in a particular package, please? I looked at exists and objects, but they seem to refer to an environment rather than a package. I was thinking of something like: ifelse(exists(functiona) in MASS, print(1:10), print(5)) Thanks, Erin -- Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences

r-package-devel is probably a better place to post this, especially if you do not get a satisfactory reply here. This list is about R programming, as you presumably know; your query is not.

Dear R People: Is it possible to run R on an iPad, please? For some reason, I'm thinking that you can't have Fortran, C, etc., so you can't do it. But I thought I would check anyway.

Dear R People: Here is something that I am sure is very simple. I'm just trying to re-create the C convolution example in the Extensions manual. Here is the subroutine: void convolve(double *a, int *na, double *b, int *nb, double *ab) { R_len_t i, j, nab = *na + *nb - 1; for(i = 0; i < nab; i++) ab[i] = 0.0; for(i = 0; i < *na; i++) for(j = 0; j < *nb; j++) ab[i + j] += a[i] *

Dear R People: I have the following equation: $1 - \frac{R}{100} = \frac{2y}{10000}$ and I was wondering if there was a way in R to solve for R (no pun intended). I'm experimenting with Ryacas, but nothing yet. Version R-3.0.1 on Windows 7.
