Hello, I'm reading Time Series Analysis and its Applilcations with R Examples and I have a question... I notice that in the book there are timeseries plots but without the x-axis being labeled with dates. They are just numbers 1,...50,...100, etc. How do I get the date to show up on the x-axis? Here is my dateframe: > head(myData, 5) 1 2008-01-30 08:30 7.00 2

Hello! I need some help, because I don't know how this error means: Error: variables ?Output1?, ?Output2?, ?Output3?, ?Output4?, ?Output5? were specified with different types from the fit Execution halted Can you help me? Thank You

R-helpers: I tried googling and couldn't find anything. I have a function I am sourcing into R that does some calculations to generate a simulated dataset. I currently have a a list set up to store the outputs from the function and a plot of one of them (a set of ordered pairs) like this: foo<-function(x,y,z){ ## do some work here ## list(x=x,y=y,z=z,output1=output1,output2=output2,

Hi r users, I have two data sets (X1, X2). For example, time1<-c( 0, 8, 15, 22, 43, 64, 85, 106, 127, 148, 169, 190 ,211 ) outpue1<-c(171 ,164 ,150 ,141 ,109 , 73 , 47 ,26 ,15 ,12 ,6 ,2 ,1 ) X1<-cbind(time1,outpue1) time2<-c( 0 ,8 ,15 , 22 ,43 , 64 ,85 ,106 ,148) output2<-c( 5 ,5 ,4 ,5 ,5 ,4 ,1 ,2 , 1 ) X2<-cbind(time2,output2) I want to

I'm trying to figure out how to repeat a series of commands in R and have the outputs added to a dataframe after each iteration. My code starts this way... a<-read.csv("File1.csv") b<-read.csv("File2.csv")

I need some sort of utility to calculate a checksum of an Ogg file. Two differently encoded Ogg:s should give different checksums, but the same file with different tags should give the same result. (The serial number doesn't work here, obviously. I need something that is changed if a bit of the file is lost.) -- Björn Lindström <bkhl@elektrubadur.se> http://bkhl.elektrubadur.se/

Hi,there I'm doing some R batch jobs in Unix. Something like R <prog1> output1 --save & R <prog2> output2 --save & prog1 and prog2 are running at the same time and they are essentially same except it contains different parameter values. I was wondering if two processes will affect each other? Hopefully they are two independent jobs. It's a beginner's question

Dear all: I'm trying to fit the optimal Box-Cox transformation related to nls (see the code below) for the demand of money data in Green (3th Edition) but in the last step R gives the next error message. Error en `[.data.frame`(eval(object$data), , as.character(formula(object)[[2]])[2]) : undefined columns selected. ?Any idea to solve the problem? Thanks in advance,

Hello, I have a number of files output1.dat, output2.dat, ... , output20.dat, each of which monitors several variables over a fixed number of timepoints. From this I want to create a data frame which contains the mean value between all files, for each timepoint and each variable. The code below works, but it seems like I should be able to do the second part without a for loop. I played

Hi all, I have a function - let's call it "myfunction". This function is based on some random number generator. Now, once in a while the function will break/crash depending on the random number it generate inside the function. To avoid the problem, what I intend to do is the following: 1. Catch the try-error using class. 2. Redo the function if it returns "try-error" 3.

Hi I want to sum over one of the dimensions of a n x k1 x k2 array in which each column is the product of the corresponding columns from two matrices with dimensions n x k1 and n x k2. I can see two approaches: a loop on k1 and a loop on k2. But I cannot figure a solution that avoids the loop? Is it possible? (I don't refer to apply or lapply etc either as they are just hidden loops so,

Hi Duncan, Do you have sources also in the $LLVM_SRC_ROOT/projects/test-suite/External/SPEC/CINT2000/164.gzip? The following is content of above directory in my case. I have copied the CINT2000 sources in this directory manually. $ls -1 $LLVM_SRC_ROOT/projects/test-suite/External/SPEC/CINT2000/164.gzip 164.gzip.reference_output 164.gzip.reference_output.small compile_info compile_parms

Hi All, I am trying to configure llvm so with test-suite enabled. I have downloaded the test-suite. Spec 2000 benchmarks sources are plugged in speccpu2000 at $LLVM_SRC_ROOT/projects/test-suite-externals/speccpu2000/benchspec e.g.: 164.gzip dir is $LLVM_SRC_ROOT/projects/test-suite-externals/speccpu2000/benchspec/164.gzip My configure command is: ../configure --disable-optimized

Hi Daya, > checking for spec2000 benchmark sources... no, not found in > $LLVM_SRC_ROOT/projects/test-suite-externals/speccpu2000/benchspec I have 164.gzip at $LLVM_SRC_ROOT/projects/test-suite/External/SPEC/CINT2000/164.gzip and it seems to work. Ciao, Duncan.

Hi Everybody, I am a total beginner at this so please bear with me. I downloaded by hand the file WIG20.txt (Warsaw Stock Exchange Index of 20 most important stocks).
