similar to: How to set read.table variables to vectors?

The variable "iter" from read.table takes on values of 0,5,10,15, and 20. I am trying to pick off values of iter by assigning it to "grp", and e.g. iter<-5, then fill the x and y vectors and make plots of x,y for each value of iter (>0) For some reason all of the plots are the same, so I am not changing x and y. Any sugestions on how to refill vectors x and y when

Dear R users, glm.fit() gave me the same AIC's regardless of TRUE or FALSE intercept option. > myX <- as.matrix(1:10) > myY <- 3+5*myX > foo <- glm.fit(x=myX, y=myY, family = gaussian(link = "identity"), intercept=TRUE) > foo$aic [1] 38.94657 > foo <- glm.fit(x=myX, y=myY, family = gaussian(link = "identity"), intercept=FALSE) > foo$aic [1]

Hi All, I have a quick question about using plot.Predict now that the rms package uses lattice. I'd like to add tick marks along the regression line, which is given by data=llist(variablename) in the plot call. The ticks show up fine, but I'd like to alter the color. I know the ticks are produced by scat1d, but after spending a fair bit of time going through documentation, it still

Dear R-List, I've written some code to put measurement values at a position x and y in bins (xb and yb). It works, but I wonder if there isn't a function that would do what I do by hand in "# fill data in bins"? Here is the code: # data x <- c( 1.1, 1.5, 2.3, 2.5, 2.6, 2.9, 3.3, 3.5 ) y <- c( 6.3, 6.2, 5.9, 5.3, 5.4, 4.2, 4.8, 4.6 ) val <- c( 50, 58, 32, 14, 12,

Hi Duncan, Yes, exactly. However, we need define Opcode MIN/MAX Into ISDOpcodes.h. Do you like to add those two definitions Into the tree?

Hi John, It seems the dereferencing a NULL pointer is undefined behavior but Calling a function through a null pointer seems o.k. If so , for this place, we need comment out the check. http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_active.html#232 look at Notes from the October 2003 meeting.

Hi Yin, MCA does support the –mcpu and –mtriple options. We have one arm test in llvm/test/tools/llvm-mca/ARM for a cortex-9, which is an Out of Order chip.

Hi Yin, I second David's words. I use shared libs myself on debug builds, but static builds with gold on a local disk is pretty feasible. Before I used gold, I had to have 16GB of RAM on my laptop, now I need less than 8GB for static builds. On 28 January 2016 at 23:58, Yin Ma via cfe-dev <cfe-dev at lists.llvm.org> wrote: > It is O.K.

Hi Matt, Thanks you so much for the reply! I've tried the llvm-mca, it is helpful. I was wondering whether the llvm-mca support the assembly code for the ARM? I cross-compile the test file for ARM like that: clang test.c -O2 -target arm-linux-gnueabihf -static -S -o test.s If I want to check the performance using llvm-mca, is there any option of "-mcpu" for ARM ? Thanks, Yin

Hi Duncan, To use select, usually, there is a compare before select. Presence of comparison will disable some opportunities to optimize some code. Select and Compare is not associative neither.

Hi David, I assume you have a powerful machine. Our drive space is on network mounted machined by IT department. The machine is default Ubuntu setup with 8 cores. Shared build is showing huge advantage due to size reduction. I will try those two debug options to see how it works.

I'm not understanding something. I'm trying to add xlab & ylab to a balloon plot of a table object. From docs I thought following should work: require(gplots) # From balloonplot example: # Create an example using table xnames <- sample( letters[1:3], 50, replace=2) ynames <- sample( 1:5, 50, replace=2) tab <- table(xnames, ynames) balloonplot(tab)

Dear all, I am trying to calculate the fitted values using a ridge model (lm.ridge(), MASS library). Since the predict() does not work for lm.ridge object, I want to get the fitted_value from the coefficients information. The following are the codes I use: fit = lm.ridge(myY~myX,lambda=lamb,scales=F,coef=T) coeff = fit$coef However, it seems that "coeff" (or "fit$coef") is

Hi, For a small case, that calls NULL pointer function. LLVM explicitly converts It to a store because it thinks it is not reachable like calling undefvalue. In InstCombineCalls.cpp:930 I think it is not a right approach because calling null pointer function Will segfault the program. Converting to a store will make program pass Silently. This changes the behavior of a program.
