I am a new user and want to learn R from the most basic level. Suggest me a reading or a link. Thanks Varsha P.S. I would appreciate if you could also send me the link where I can read questions and answers posted by others. [[alternative HTML version deleted]]

Hi R users: I got an error that "l1" is not found. This is a sample code: f1<-function(i,l1){ print(l1[[i]]) l1[[i+1]]<<-i return(i) } z1<-list(x=100,NULL,a=c(1,1)) lapply(1:3,f1,l1=z1) My final goal is to update the value of each list component to use it in the following step. I see that print function founds l1[[1]], but the assign instruction not. Thank you

I have two factors l1, l2, and I'd like to merge them. (Remark: The factors can not be converted to charaters) Function c() does not give me the result I want: > l1 = factor(c('aaaa', 'bbbb')) > l2 = factor(c('ccc', 'dd')) > lMerge = factor(c(l1, l2)) > lMerge [1] 1 2 1 2 Levels: 1 2 > I'd like to merge l1 and l2 and to get lMerge

Hi R users: f1<-function(l1,idx){   f2<-function(i,l1)   l1[[i+1]]<<-c(l1[[i]],l1[[i+1]][-1])   lapply(idx,f2,l1)   return(l1) } l<-list(c(1,2,3),c(4,5),c(6,7,8)) l2<-f1(l,1:(length(l)-1)) l2 I got: [[1]] [1] 1 2 3 [[2]] [1] 1 2 3 5 [[3]] [1] 4 5 7 8 But what I want in the last position of l2 is the acummualte of the assignations... I would like to have: [[1]] [1] 1 2

I want to superimpose two functions plots in the same page. The functions L0 and L1, defined below f0 <- function(mu, xm, ds, n) { 1 - pnorm((xm-mu)/(ds/sqrt(n))) } f1 <- function(mu,n) f0(mu, 386.8, 48, n) L0 <- function(mu) f1(mu, 36) plot(L0,ylim=c(0,1),xlim=c(360,420)) L1 <- function(mu) f1(mu,100) lines(L1) The plot of L0 works pretty well. However, when

Hello, I am trying to write a new ModulePass using LoopInfo analysis result, but it seems I misunderstand some concept about PassManager. Basically I want to keep LoopInfo analysis result alive. Here is an example showing the problem I encountered, assuming I already addRequired<llvm::LoopInfo>() in getAnalysisUsage: void foo(llvm::Function *F1, llvm::Function *F2) { llvm::LoopInfo

To superimpose two functions plots in the same page. The functions L0 and L1, as defined below, I use the following code: # An accumulative normal distribution function with # several parametres f0 <- function(mu, xm, ds, n) { 1 - pnorm((xm-mu)/(ds/sqrt(n))) } f1 <- function(mu,n) f0(mu, 386.8, 48, n) # Two functions with just the parameter mu L0 <- function(mu)

Dear R-helpers, Please have a look at the following. f1 is the same as f2 except that it has some values replaced by NA. But it's corresponding file is slightly bigger than the file containing f2. Could someone please tell me if this is an anomaly ? > load("file1") > ls() [1] "f1" > load("file2") > ls() [1] "f1" "f2" > >

Thank you for your quick reply. Actually I am using a std::map to map Function* to LoopInfo*, but that does not help in this case. Each time I call getAnalysis<llvm::LoopInfo>(*F), it returns the same instance of llvm::LoopInfo, so the std::map is just mapping every function into the same instance. It seems only the analysis result for the last function is valid, because all the result for

Hi all, I didn't get a response to my post of this issue a week ago, so I've tried to clarify: When I use lme to analyze a model of nested random effects, the variance estimates of levels higher in the hierarchy appear to have much more variance than they should. In the example below with 4 levels, I simulate variance in level 2 (sd=1.0) and level 4 (sd=0.1), but levels 1 and 3 do

Hi, I'm plotting a bar chart like this: ggplot() + geom_bar(data=res,aes(fill=f1,x=f2,y=y),stat="identity",position="dodge") f1 contains quite a few levels and the plot is really quite difficult to read when the order of bars on the graph and on the legend does not match. This problem has been discussed recently here:

Thanks for your reply Quentin. I do understand that the registers are allocated much later in the pipeline. I am assuming that the physical registers are allocated before MipsAsmPrinter class. I am doing something like if (MI->getOpcode() == Mips::OPCODE) { unsigned n = MI->getNumOperands(); for(unsigned i=0 ; i < n ; i++) { const MachineOperand &MO =

Hi thank you for talking the time to help me with this. I have a sequence of numbers in a file and an equal sequence of various character, say(a b c d) each occurs more than once. I need to plot the numbers so that numbers corresponding to a in the other sequence would have green dots, those corresponding to b a red dot, nothing on c and blue square for d. i.e 2 a show a green dot 4 b show a

Hi, table1D() below can be up to 60x faster than base::table() for the 1D case. Here are the detailed speedups compared to base::table(). o With a logical vector of length 5M: 11x faster (or more if 'useNA="always"') o With factor/integer/numeric/character of length 1M and 9 levels (or 9 distinct values for non-factors):

Hi! I have tried to print text with Latin-1 characters (????) from R to postscript and X11 window but when I'm using the interactive R-shell, I can't get them printed even from keyboard. Is there some configuration flags to use 7-bit or 8-bit character sets? TIA Juha -- : Juha Tikkanen -- juha.tikkanen at edita.fi -- http://www.edita.fi/ : : tel +358-9-566 0532 -- mob +358-40-557
