Hi there, sorry for troubling everybody once again, I've got a problem rewriting Sarkar's function for rewriting the tick locations in a logaritmic way (s. http://lmdvr.r-forge.r-project.org/code/Chapter08.R): His example works for log 2 but I need log e (natural logarithm). My problem is that if I replace 2 with "e" (using paste()), I get the error message that the location

Hello! I'd like to have a function to draw correct grid while using log axis with xyplot from lattice package. Right now I have the following code inside of my panel function: lim <- current.panel.limits() v <- latticeExtra:::logTicks(2^lim$xlim, loc=1) h <- latticeExtra:::logTicks(2^lim$ylim, loc=1) panel.abline(h=log2(h), v=log2(v), col="LightGray") Is there an easy way

Dear R list members, I'd like to make a graph of coefficients of the intercept, variable 1, and variable 2 (and possibly the interaction between variable 1 and variable 2). When I use the lmList function as attached below, it shows a nice coefficient graph. > PACRP.lis <- lmList(PAffect ~ CRPC + CRPT + CINT | ID, redinteract) > coef(PACRP.lis) > PACRPlis.coef <-

I'd like to learn the process of revising R functions & packages and then submitting proposed patches to the R Core team. Would someone be willing to mentor me through one example? For starters, consider an example. I'd like to revise the t.test function to return the stderr value to the user. We only need to change the "rval" in the third-from-the end line of

I would like to set the y axis limit of an xyplot using the object 'ylimit', but receive this error: [1] 990 Error in extend.limits(limitlist[[i]], axs = axs) : improper length of lim I get the same error if I use ylim. library(lattice) trellis.device(col = FALSE, theme = lattice.getOption("col.whitebg")) name <- "Variable name" symbols <-

dear LLVMers, I am trying to use some of the LLVM alias analyses, and I would like to check two things with you: is scev-aa being maintained in LLVM 3.7? Second question: I run cfl-aa, and I got a very small number of pointer disambiguation (no alias) with it. My results for SPEC CINT 2006 follow below. Is this low number of no alias responses something to be excepted? Below the results that I

We'd like to be able to vary the latency of our load instructions based on what address space is being loaded from. I was thinking I could do this by overriding getOperandLatency in our target, but I'm wondering if the addrspace info is available when instructions are scheduled? For example, I have this in our llvm IR: %0 = load i32 addrspace(4)* @answer, align 4 store i32 %0, i32*

Dear R Users, I would like to plot three time series on the same graph, two axis on the left and one axis on the right. The time series that I am graphing on the left do not share a similar scale: one has a range of 1:100 and the other a range of 25000:70000. How can I display the tick marks for both on the left hand side without superimposing them, i.e. one set of tick marks in black right

Hi all, my apologies for a probably very obvious question but i can't figure out if, on a bar plot, there is a simple way to have the x-axis cross the y-axis at 1, when the y-axis is on a log-scale? I want to draw a bar plot, and have some of the bars "drop" below 1 while starting from 1. Is this possible? I have been trying various things using barplot, barplot2 etc... without

I'm beginner with R language My goal is to write a function that takes an input Erlang entering your ? Name ? Name ? Date of birth. The program will calculate age and display output first I do know the system date (month, day, year) I find with Sys.Date () I found a function. net to calculate the age Protected Sub calcul_age() Dim datetimenow = DateTime.Now Dim

Hi, what would be needed to make a C/C++ interpreter using the LLVM libraries. We have in our project (http://root.cern.ch) a C/C++ interpreter (http://root.cern.ch/twiki/bin/view/ROOT/CINT), but it has some limitations (the biggest being maintenance). I see there is a libLLVMInterpreter that can interpret the LLVM IR. Could this be used to interpret, or a starting point, to an real

I've been creating some R tools that manipulate objective functions for optimization. In so doing, I create a character string with R code, and then want to have it in my workspace. Currently -- and this works fine -- I write the code out, then use source() to bring it in again. Example: cstr<-"jack<-function(x){\n cat(\"Silly x:\")\n print(x) \n }\n" write(cstr,

As a very new user of R, and a user of S with very limited experience, I thought I would start humbly with a simple t.test. The response to the command sequence sample <- scan() 4 5 6 7 8 9 t.test(sample,mu=20) rather surprised me, because of the idiosyncratic choice of a confidence interval for the mean of the population from which the sample was drawn. I asked my colleague Bob Henery

Hello, I'm looking to calculate a 95% confidence interval about my estimate for a sample's weighted mean, where the calculated confidence interval would equal the t-test confidence interval of the sample in the case when all of the weights are equal. My initial thought was to simply implement a modified version of the t-test function but substituting the weighted variance and mean for the

I need to reliably boot a server from a USB device. Since USB device ordering can be unpredictable, I wrote a simple early-userspace "init" program to find the root FS on the correct USB device & partition. I have "labeled" the root ext2 FS on the USB drive, and the program searches for the label by examining the bytes at a specific offset from the beginning of the

If I run a docker image with the mesos containerizer and altering the dovecot config mentioned here[1] I think the root detection is incorrect because it looks like dovecot is still thinking it is root. I still get errors like: >> log(829825): Fatal: We couldn't drop root group privileges (wanted=10053(dovecot), gid=0(root), egid=0(root)) Why does it want to drop to root, if we

Hi. I'd like to do a t-test to compare the Delta values of items with Crit=1 with Delta values of items with Crit=0. What is the t.test syntax? It should produce a result like this below (I can't get in touch with the person who originally did this for me) Welch Two Sample t-test data: t1$Delta by Crit t = -3.4105, df = 8.674, p-value = 0.008173 alternative hypothesis: true

I have a problem with lattice log scales that I could use some help with. I'm trying to print log y-axis scales without exponents in the labels. A similar thread with Deepayan' recommendation is here: http://tolstoy.newcastle.edu.au/R/e11/help/10/09/9865.html. For example, this code using xyplot produces a logged y-axis but the labels (e.g. "10^1.2") are not very

Hello, I wuold like to propose my modifications of the original cor.test to you : I tried to calcolate the correct p-value for Spearman and Kendall's test with ties. Let me know what you think.
