Hello folks: I have a data frame which includes two numeric vectors: "Pa1" and "Ingr" (which represents income).  I run the following code on the R console: ingreso <- factor(ifelse(Ingr<=3000,"bajo","alto")) tapply(Pa1,ingreso,summary) boxplot(Pa1~ingreso) and it works fine.  However, when I "Sweave" through an rnw file containing that

Hi, I have run a groups of t test and obtained a list of the t-test results (about 30). How do I extract p-values from the 30 t-test results and make a table output? Thanks Jun Example t-test output: ============================ $Lambda_z Welch Two Sample t-test data: x[PA1.BS.DN$Onecode == 2] and x[PA1.BS.DN$Onecode == 3] t = -0.1128, df = 33.635, p-value = 0.9109 alternative

I have just started using ggplot2 and I seem to be doing something stupid in writing ggplot2 commands on more than one line. In the example below the commands on one line are working fine, but as soon as I put them on two lines I get an error. Can any one point out what I am doing wrong? It must be something blindingly simple. Thanks Example

I have a zoo object that contains 2 time series named "A-B" and "V1". When I create a third series "V2", the name of the "A-B" series is changed to "A.B". Although I could recreate the names for the 3 series I am wondering if there is a way of preventing the name change from happening ( ... maybe an equivalent of the keep.names=TRUE statement

I am running the following line to download data from the US Energy Information Administration.

Hi All Apologies if this is not the correct list for this question. The Rglpk package offers the following example in its documentation library(Rglpk) ## Simple mixed integer linear program. ## maximize: 3 x_1 + 1 x_2 + 3 x_3 ## subject to: -1 x_1 + 2 x_2 + x_3 <= 4 ## 4 x_2 - 3 x_3 <= 2 ## x_1 - 3 x_2 + 2 x_3 <= 3 ## x_1, x_3 are non-negative integers ## x_2 is a non-negative real

I am trying to rename column names in a dataframe within a function. I am seeing an error (listed below) that I don't understand. Would be grateful of an explanation of what I am doing wrong and how I should rewrite the function to allow me to be able to rename my variables. Thanks. # Test Function myfunc <-function(var){ d = c(1,2,3,4,5) dts =

I have a snom PA1, works fine. I am trying to get it work with multicast and asterisk 11.16 my other devices are accepting multicast.

Hi all, I have had (what I consider) an odd request. The installation I'm working on now is an office on a multi-floor building. They 're looking for some kind of solution with the phone system to provide door control. We are a non-profit so of course I'm looking for something VERY inexpensive. I'm sure /someone/ has done something like this. I'd appreciate any ideas. Cassius

Hi, While installing precompiled packages I often get warnings like the one in the subject. I usually ignore them, but I still do not understand why windows packages are build with unreleased versions of R. Is there some way to get packages build under R-2.2.0? What are potential problems that can result from that version mismatch? My system: winXP R version: 2.2.0 Jarek Tuszynski

Thanks for your help with this problem about dynamic linked libraries. I thought I had it solved, but apparently not. Below is a small piece of Pascal code that I compile into a library. When I load the library using dyn.load R becomes very unstable. The Mac GUI crashes in all kinds of situations --even moving a window can sometimes crash it. Running from the command line (I thought the

Hi All I am running a linear regression using the lm object. In the event that my independent variable is the same across all observations the regression slope is returned as an NA. For example, if I have the following y=c(10,12,17) x=c(5,5,5) lm = lm(y~x) produces the following Coefficients: (Intercept) x 13 NA Other than post-processing the results, is

Dear all, Can anyone please help me about any of the following questions: -------------------------------------------- 1. How can i find "factorial" of any number in R? I tried > prod(170:1) # to find factorial of 170 or 170! Is it the only procedure - or R has any better process / operational character to calculate factorial? Also, is it possible to calculate factorial of 500? Or

Hi All I am trying to use the round function on some columns of a dataframe while leaving others unchanged. I wish to specify those columns to leave unchanged. My attempt is below - here, I would like the column d3 to be left but columns d1, d2 and d4 to be rounded to 0 decimal places. I would welcome any suggestions for a nicer way of doing this. d1= rnorm(10,10) d2= rnorm(10,6) d3=
