Hi, I'm running R 2.11 Does anyone know if it possible to transform one character vector to one character string ?

Sorry, I just realized I didn't type in the correct names of the variables I am working with, this is how it should be: plot(1,1,type="n") for (i in summ$tx) { points(summ$timep[summ$tx==i],summ$mn[summ$tx==i]) lines(summ$timep[summ$tx==i],summ$mn[summ$tx==i]) } Thank you, Judith ____________________________________________________________________________________

Dear R-help, I am trying to create groupedData objects using the nlme library. I'm missing something basic, I know: Here is the first example in ch.1 of Pinheiro & Bates (2000): library(nlme) x2=Rail$travel;x1=Rail$Rail;eg1=data.frame(x1,x2);eg1gd=Rail print(eg1gd) x11();print(plot(eg1gd)) femodel=lm(x2~x1-1,data=eg1gd) print(femodel$coefficients) Result: x12 x15 x11

Hello! I am having an issue with the OrgMassSpecR package. I run my HPLC using a DAD detector. My raw data is exported form chemstation as a csv file. I then upload the csv into Rstudio no problem. Using the DrawChromatogram function, I get a nice chromatogram, and my retention time, peak area, and apex intensity values are given as well. The problem comes with the peak area value given. The

I've setup rsync 3.0.0 pre5 on distrib-coffee.ipsl.jussieu.fr (rsync server) and upload the same into mandriva cooker (development distribution). Someone reported this failure: rsync -auvPH --delete --exclude-from="/home/rfox/exclude.txt" distrib-coffee.ipsl.jussieu.fr::mandrivalinux/devel/cooker/i586/ . receiving incremental file list rsync: hlink.c:253: check_prior: Assertion

Hi, I seem to be having a problem adding the following two raster objects together - one is a rasterLayer, the other is a rasterBrick. The extent, resolution, and origin are the same, so according to my understand it should work. The objects look like so: > obs.clim class : RasterLayer dimensions : 60, 200, 12000 (nrow, ncol, ncell) resolution : 0.5, 0.5 (x, y) extent : -70,

Dear R Users, I am using R on windows. how to use 'points' function to plot two curves with errbar I am doing like: x.val <- as.integer(names(co2mean)) errbar(x.val, co2mean, co2mean + co2sd, co2mean - co2sd, xaxt='n', col=1, xlab=NA,ylab=NA)# obs error bar lines(x.val, co2mean, col=1, lwd=2) errbar(x.val, co2tm3.month.mean, co2tm3.month.mean + co2sd.tm3, co2tm3.month.mean -

hello - a question about filled.contour plots, for which i haven't found a response in previous posts - sorry if already treated. i'd like to draw several filled.contour plots (that is, maps) on the same device (a postscript file, actually). I know about layout(matrix) , split.screen or par(mfrow) : it works well for simple plots, but with filled.contour plots, i get several pages

My R version is 2.7.1 (on Debian) and some packages are asking for > 2.10. I've done all things from http://cran.r-project.org/bin/linux/debian/ but to no success.

Hello Akshay, R is quite inspired by LISP, where this is a common thing. It is not in fact that {...} returned something, rather any expression evalulates to some value, and for a compound statement that is the last evaluated expression. {...} might be seen as similar to LISPs (begin ...). Now this is a very different thing compared to {...} in something like C, even if it looks or behaves

Dear all, I am trying to find a suitable R-function for parametric proportional hazard regressions. The package survival contains the coxph() function which performs a Cox regression which leaves the base hazard unspecified, i.e. it is a semi-parametric method. The package Design contains the function pphsm() which is good for parametric proportional hazard regressions when the underlying base

R's { expr1; expr2; expr3} acts much like C's ( expr1, expr2, expr3) E.g., $ cat a.c #include <stdio.h> int main(int argc, char* argv[]) { double y = 10 ; double x = (printf("Starting... "), y = y + 100, y * 20); printf("Done: x=%g, y=%g\n", x, y); return 0; } $ gcc -Wall a.c $ ./a.out Starting... Done: x=2200, y=110 I don't like that

Dear Valentin, But why should {....} "return" a value? It could just as well evaluate all the expressions and store the resulting objects in whatever environment the interpreter chooses, and then it would be left to the user to manipulate any object he chooses. Don't you think returning the last, or any value, is redundant? We are living in the 21st century

Valentin, in terms of limitations as Sean pointed out, an important one is that .mir doesn't have MachineFunctionInfo which may result in failure on accesses to global variables due to use of register X2. The verifier considers it an undefined register. Also, it's probably easier to reduce test cases using bugpoint starting from an IR test case. With the code you provided, I get a

I wonder if the real confusino is not R's scope rules? (begin .) is not Lisp, it's Scheme (a major Lisp dialect), and in Scheme, (begin (define x ...) (define y ...) ...) declares variables x and y that are local to the (begin ...) form, just like Algol 68. That's weirdness 1. Javascript had a similar weirdness, when the ECMAscript process eventually addressed. But the real

Hi all I'm trying to do a live migration with non-shared storage on CentOS 7. It was working well doing it from CentOS 6 to CentOS 7 but not between to CentOS 7 machines. I read that this feature was removed in RHEL/CentOS 7 but should be available in the CentOS-QEMU-EV repository. But I still get the error using qemu-kvm-ev: error: internal error: unable to execute QEMU command

I am trying to install the maverick version. The lucid version works flawlessly, but this one promts this messages. The following packages have unmet dependencies: r-base: Depends: r-base-core (>= 2.12.0-1maverick0) but it is not going to be installed Depends: r-recommended (= 2.12.0-1maverick0) but it is not going to be installed Recommends: r-base-html but it is not going

I'm not sure if this helps, but here it is in case it does. I typically use bugpoint in a way as to keep the actual failure that I'm after. For example, with the test case you've pasted, I was looking for a specific assert. So I used bugpoint this way: $ cat reduceme.sh #!/bin/bash llc -filetype=obj $1 2>&1 | grep 'Cannot lower calls with arbitrary operand bundles'

Hello, I am trying to isolate an assertion failure in if-converter (on PPC) and I generated a textual debuglog with: ``` LLVM_ARGS=-print-before-all -print-module-scope -filter-print-funcs=japi1__require_7687 ``` and after splicing out the the MIR before the if-converter pass I would like to run `llc -march=ppc64le -run-pass=if-converter input.mir` so that I can start minimising the MIR. This

Returning the last value of { is the basis of functions not needing a return statement. Before R invokes a function (specifically a closure), it creates a new context. When R evaluates a call to return, it looks for a context to return from and finds the context of function, ending the context and the evaluation of the function body early. However, if you don't use return, R just returns the
