similar to: Graphics window always overlaps console window!

I'm only getting a text console with CentOS-7.2 on my (oldish) HP MicroServer. The only explicit error I see in Xorg.0.log is that no driver is found for my Pixart USB optical mouse. My query is: would that be sufficient to prevent a graphic console? Incidentally, I can use X apps, eg xpdf, if I ssh in from my laptop. As always, any advice gratefully received. -- Timothy Murphy

Like kile for LaTeX, Linux/KDE's kate editor is an excellent editor for R, with easy code submission to a running R process. Syntax highlighting is good. I have not been able to figure out two things: - how to automatically reformat a line or region of text using good indentation rules (Emacs/ESS make this so easy by just hitting Tab while the cursor is in a line, or highlighting a

Hi R-helpers, I wish to produce frequency histograms of all of the variables in my dataframe (except some identifying variables). I have tried >hist(dataframe[,3:20]) to produce histograms of the 3rd through 20th variables in my dataframe, but R doesn't like that. Could anyone provide a suggestion? Also, once I produce the histograms, I'd like to save them as graphic files on my

Hi, anyone knows about any functions in R can get multidimensional integration not over a multidimensional rectangle (not adapt). For example, I tried the following function f(x,n)=x^n/n! phi.fun<-function(x,n) { if (n==1) { x }else{ integrate(phi.fun, lower=0, upper=x, n=n-1)$value } } I could get f(4,2)=4^2/2!=8, but failed in f(4,3)=4^3/3! Thanks Best, Lynette

Dear list, I found a strange behavior of the graphic display when using bquote to set a title to a plot. The problem arise when you manually resize the graphic window using the mouse. It happens on both quartz and x11 devices. Here's a reproducible example: par(mfrow = c(1,3)) for (i in 1:3){ title <- as.expression(bquote(gamma[.(i)])) plot(1:10, main = title) } Once you ran the

I'm a long time user of R, but I'm not a regular Mac user. I am now teaching in a room with a dozen Macs and I'm having a problem printing the graphics window. I'm using R 1.5.1 precompiled for Mac OS on Blue G3s with Mac OS 9.2. When I have the macintosh graphics device selected and use File, Print from the menu system, the OS attempts to print, but the machine hangs after a

I'm trying to sort a DATAFRAME by a column "ID" that contains alphanumeric data. Specifically,"ID" contains integers all preceeded by the character "g" as in: g1, g6, g3, g19, g100, g2, g39 I am using the following code: DATAFRAME=DATAFRAME[order(DATAFRAME1$ID),] and was hoping it would sort the dataframe by ID in the following manner g1, g2, g3, g6, g19,

Given the following dataframe: A=1:10 B=(a-5)^2 DATAFRAME=data.frame(A,B) How can I sort DATAFRAME increasing (or decreasing, for that matter) by B without making reference to A, or any other column? I've read ?order and ?sort but cannot seem to figure this out. Thank you. Mark

I just noticed when using 2.6.1, 2.6.2 (2008-02-08), 2.6.2pat (2008-02-21 r44582), and 2.6.2pat (2008-03-24 r44975) on my poor old Celeron D330 (2.6 GHz; 3.5 years old) running Windows XP, that the mouse cursor appears to be redrawn more sluggishly when the pointer is over R windows graphics devices than over the R console window or other applications' windows. The slowdown seems to start only

Does anyone know how to import a SAS .sd2 file into R? I can't see anything in library(foreign). Thank you. Mark

Dear R users, Inspired by previous list discussion of the glob2rxc function, I am attempting to create a new vector called TOTAL by summing all vectors whose names begin with ABC: TOTAL = sum(list = ls(pattern = glob2rx("ABC*"))) I'm running R 2.2.1 on Windows XP. Can anyone say what I'm missing? Thank you, Mark

Dear R users I would like to make a new dataframe from an existing dataframe, retaining ONLY those variables that end in the letter "t" I have searched the help archives and consulted several reference books but cannot seem to find an example. Any ideas...? Thanks! Mark [[alternative HTML version deleted]]

Hello R-helpers, I would like to calculate least square means after having built a GLM with quasipoisson errors. In my model the dependent variable is continuous, I have one continuous independent variable and one categorical independent variable (that is the variable for which I would like to calculate the least square means). I've looked around for the command to calculate the least

Hi R-helpers, I have imported data from Excel using the following code: library(xlsReadWrite) data <- read.xls(data,colClasses=c("character")) and this results in all of the empty (blank) cells in the imported Excel file also being empty (blank) in the resulting dataframe. I am not used to having blanks (rather NAs) and I think these are caused by the colClasses argument. I would

Dear R helpers, I would like to write a loop that makes 4 objects (called A, B, C, and D) each of which contains ten random numbers. This attempt: individuals<-c("A","B","C","D") for(i in 1:length(individuals)) { individuals[i]<-rnorm(10) } does not work because "individuals[i]" is not the proper way to extract each letter from the

Hi, Anybody please tell me how to have a PV Linux with graphics? I succesfully created some PV Linux with debootstrap and xen-tools. But then all the images must be started with "xm create -c" command, and everything then is console, with no X Window. In short, I want to have PV Linux, but with X. How to do that? Thanks, H _______________________________________________ Xen-users

Hi All, I recently got some IBM Xseries 335 servers 2nd hand, and noticed they don't have any graphics card. Some google searched indicate they only have an uplink port, which you could connect to another (other model) IBM server and use that as the head node. But, I don't have one available. It has 2x GB NIC's, and what looks like a management port, but I can't figure out how to

In R on Windows (ver 7) I have somehow set the preferences for the R console window to be always on top. I'm sure at the time I did this it seemed like a good idea, but in practice it is not. Unfortunately, I cannot remember where the setting is changed, and thus it is stuck this way. Does anyone know how to modify this setting? Thanks, -Robert Robert M. Flight, Ph.D. Bioinformatics and
