Dear fellow R users, I would like to draw a "sunflowerplot" because I have data (decade by month) that plots multiple times on the same x-y co-ordinates. Further I would like to colour each of the points/sunflower leaves on the plot according to the group they belong to (i.e. which type of event each represents within that decade and month). I thought that this would be relatively

I have a list of data frames like this: a<- data.frame(x=runif(10), y = runif(10), Acc = 1) b<- data.frame(x=runif(10), y = runif(10), Acc = 0) ls<- list(a,b) and I want to remove the data frames from ls that have Acc values other than 1. How do I do that? Thanks for any help! Matthew

Hi, I want to generate a number of vectors and store them with different names, like this: x=1 while (x<100) { vector#x# = rnorm(100) x=x+1 } where each vector has, at its hand, instead of #x# a number which goes from 1 to 99. How can I do this? Thanks Gabriele Zoppoli, MD Ph.D. Fellow, Experimental and Clinical Oncology and Hematology, University of Genova, Genova, Italy Guest

Say I have: > set.seed( 1 ) > m <- matrix( runif(5^2), nrow=5, dimnames = list( c("A","B","C","D","E"), > c("O","P","Q","R","S") ) ) > m O P Q R S A 0.2655087 0.89838968 0.2059746 0.4976992 0.9347052 B 0.3721239 0.94467527 0.1765568

Hi all, In arch/x86/x86_emulate.c: x86_emulate(): 1716 case 0xfe: /* Grp4 */ 1717 generate_exception_if((m odrm_reg & 7) >= 2, EXC_UD); 1718 case 0xff: /* Grp5 */ 1719 switch ( modrm_reg & 7 ) 1720 { 1721 case 0: /* inc */ 1722 emulate_1op("inc", dst, _regs.eflags); 1723 break; 1724

Hello! So I am handling this problem with some arrays grp1-grp7, I want to write a loop to avoid tedious work, but I don't know how to transform string to boor? For example I used i=1 paste("grp",i, sep="") I only got "grp1" instead of grp1, which can't be manipulate using mean() or other function. I am not sure if I make myself clear... THANKS!!!!

With the x86 instruction emulator no pretty complete, I''d like to re-submit this patch to support cmpxchg16b on x86-64 and at once rename the underlying emulator callback function pointer (making clear that if implemented, it is to operate on two longs rather than two 32-bit values). At the same time it fixes an apparently wrong emulator context initialization in the shadow code.

Hello list, I have troubles with the daily backup of a modest filesystem which tends to take more that 10 hours. I have ext4 all over the place on ~200 servers and never ran into such a problem. The filesystem capacity is 300 GB (19,6M inodes) with 196 GB (9,3M inodes) used. It's mounted 'defaults,noatime'. It sits on a hardware RAID array thru plain LVM slices. The RAID array is

Nov 19, 2003 To Everyone on this list... What's been suggested for a FAQ and other "much needed information" for such a _HIGHLY_ technical software product has been proven thousands of times in the past few months. Even an untrained monkey can see that, including many geeks. Those that are against it are the very _few_ arrogant self-centered egotistical few that think their middle

Hi all, Given a data frame: my.df <- data.frame(a = c(1:5, 1:10, 1:20), b = runif(35)) I want to split it by "a" such that I end up with a list containing 3 components i.e. the first containing a = 1 to 5, the second a = 1 to 10 etc. In other words, sets of sequences of a. I can't seem to find the right form using the split function - can you help? Much appreciated. David

Hi expeRts, I would like to calculate weighted mean by two factors. My code is as follows: R> tmp <- by(re$meta.sales.lkm[, c("pc", "sales")], re$meta.sales.lkm[, c("size", "yr")], function(x) weighted.mean(x[,1], x[,2])) The result is as follows: R> tmp size: micro yr: 1994 [1] 1.090
