Spill hoisting on RAL: looking for some debugging ideas
Hi, I am debugging private backend and faced interesting problem: sometimes spill hoisting creates double stores. (some output from -debug-only=regalloc). First hoisting: Checking redundant spills for 0 at 16r in %vreg19 [16r,144B:0)[144B,240B:1)[240B,280r:2)[296r,416B:3)[416B,456r:4)[472r,592B:5) 0 at 16r 1 at 144B-phi 2 at 240B-phi 3 at 296r 4 at 416B-phi 5 at 472r Merged to stack int: SS#0 [16r,592B:0) 0 at x hoisted: 16r STbo %vreg19, <fi#0> Second below: Checking redundant spills for 0 at 16r in %vreg19 [16r,96B:0)[144B...

color scale to label a plot
Hello R-helpers I want to put a color scale in a plot: I've got an xy plot where the values of the response (z=f(x,y)) is symbolically given by colors (like heat or rainbow color scale) I would like to put such a scale with apprpriates labels in the plot, so as to facilitate the interpretation (like in a finite elements result plot) How is taht possible? Thanks Anne [[alternative

[ARM] Register pressure with -mthumb forces register reload before each call
If I'm understanding what's going on in this test correctly, what's happening is: * ARMTargetLowering::LowerCall prefers indirect calls when a function is called at least 3 times in minsize * In thumb 1 (without -fno-omit-frame-pointer) we have effectively only 3 callee-saved registers (r4-r6) * The function has three arguments, so those three plus the register we need to hold the

Request for new Windoze GUI Widget

Kudos to the R support team
Hi there, I just wanted to take a quick second to thank everyone who maintains this service- just in case you don't hear it enough, there are a plethora of people who rely on this service (as evidenced by the help archives), and even if they don't say it, are greatly thankful for what you do here. Not only are you providing a service to people who are learning R, but indeed helping

accessing function arguments as text, macro style
Hi. In a case like this, I can get strip headings that have the name "c" and the value for c. d <- data.frame(a=1:5,b=6:10,c=11:15) > xyplot(a ~ b | paste("c", c), data=d) > For more complicated examples, instead of using paste repeatedly I would like to use a function. It seems like what I really want is a macro, though. I'm not quite familiar enough

Title with substitute and paste
Hello All, I am generating some plots where the title is generated with substitute and paste. An example: nval <- 20 plot(0,0) title(substitute(paste("n = ", n), list(n = nval))) But when compared to: plot(0,0) title("n = 20") the title in the first plot looks slightly different (it is not in bold). How can I get the two titles to look exactly the same? Also, how can I

Different results
Hello everybody, I've been practicing with some data in R and SPSS and I noticed that there are some differences in ANOVA results. For example with : y<-c(1,2,34,2,3,45,2,1,67,3,2,67,2,2,98,4,4,23,1,1,23,2,3,45) and x<-rep(c(1,2,3),8) I get in R ( with summary(aov(y~x)) ) MSres=350.7 df=22 while in SPSS I get MSres=221.9 df=21 Can enyone explain me what is the problem or

Sorting Data?
Hello, Im reading through some manuals, but I cannot find my answer. I have a file containing many data: Vpn Code Family Age F1 F2 ... F17 1 1 M 46 1 2 ... 1 2 1 D 18 3 2 ... 4 3 2 M 50 3 3 ... 3 ... and so on. Now I can read it by: F = read.table("file", header=T) but now I want to seperate the mothers (M) and daugthers (D) of the family with all the data in all other fields.
