Dear R People: I'm building R-2.12.1 from scratch on a Windows XP machine. The "make all recommended" worked fine, but when I did the make in the bitmap directory, I got the following error: C:\R\R-2.12.1\src\gnuwin32\bitmap>make make make CC='gcc -std=gnu99' AR='ar' \ CFLAGS="-O3 -I../../../extra/zlib -DPNG_NO_MMX_CODE" \ RANLIB=ranlib

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 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: 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: Suppose I have the following: "pi/2" and I would like it to be 1.57..... Using as.numeric, here is my result: > as.numeric("pi/2") [1] NA Warning message: NAs introduced by coercion > Is there a way to produce the numeric result, please?

Dear R People: I have a question, please: I want to install a package from R CMD INSTALL and I have a boatload of configure args. I want to put them into a file. How do I point the R CMD INSTALL to that file, 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 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: 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: 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

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

Dear R People: Is there a function to convert a character string to all uppercase or all lowercase please? I'm sure that I've used one before but I'm drawing a blank.

Dear R People: Is there a way to "guarantee" that breaks=n will give you exactly n breaks, please? I'm fairly certain that the answer is "no", but thought I'd check.

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.

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 have a barplot created from a table. What is the best way to set up the barplot such that is shows probability rather totals, please? I've tried plot also but it shows horizontal bars rather than vertical bars.
