Hi You wrotte me in R help and I´m very gratefull. I couldn´t reply because an illness. I writte this to see if you can help to solve. I´m a begginer (I´m 20 years old ) but I´m trying to learn more about this program also I´m learning Octave. I need to create a matrix in R whose values depends on the values of other matrix. You see: I have a first "R" matrix whose first row and

Hi I want to simulate random numbers normal distributed with this size (2000,10000). I tried this but my computer exhaust there is a fast way to make it? randz<-matrix(rnorm(2000000),2000,10000) [[alternative HTML version deleted]]

Hi all, I want to make the following: I want to run a linear regression on each column of a matrix "estima" on the correspondent column on the matrix "estima2". You see I want to regress estima[,1] on estima2[,1] this way to all columns.... At the same time I want to make a regression adding each time a new observation. You see, the first regression will regress only one

Dear R-helpers, I'm trying to develop a function which specifies all possible expressions that can be formed using a certain number of variables. For example, with three variables A, B and C we can have - presence/absence of A; B and C - presence/absence of combinations of two of them - presence/absence of all three A B C 1 0 2 1 3 0 4 1 5 0 6 1

Dear R Users, Is it possible to make file names dependent on a changing variable? For instance. I generate random numbers in a loop and at each iteration I want data to write to file (I do not want to write everything in one file using 'append'): for (i in 1:50){ x<-matrix(runif(100, min=0,max=1),nrow=5,ncol=20) Write(t(x),file="Data_i.txt",ncolumns=5,sep="\t") }

Dear all, I have a 10 columns matrix which has 2^10=1024 unique rows, with values 0 and 1. What I would like to do is a little complicated; in a simple statement, for a subset (say 1000 rows) I want to perform pairwise comparisons between all rows, find out which rows differ by only one value, replace that value by "x", get rid of the comparisons that differ by more than one value

Hi all, I want to plot trough pairs() plot a matrix with 4 columns. I want to make a trhee plot in a graph. Plotting pairs colum 2,3,4 on y axis and 1 on X axis. You mean (a plot with three graphs) ommitting the first pair with itself. And only the pairs with colum 1 with the other not all pairs. I. e. this matrix 4177 289390 8740 17220 3907 301510 8530 17550 3975 316970 8640 17650 3651 364220

Sorry all for these two easy questions: First, I have a matrix with trhee columns: A= Name Eight Puntuation Pepe 1,85 10 Paco 1,7 7 Pablo 1,82 6 I want to scatter the two columns (I could use pairs or other functions...) but the only doubt is that I cannot find the way to add in the associated intersection (the point scattered) the label "Pepe" "Paco" and so

Hi I have an output data Data.csv this style: ,"V1","V2","V3" 1,"-9552","9552","C" 2,"0","9653","0" 3,"9614","9614","V" 4,"0","9527","0" 5,"-9752","9752","C" 6,"0","9883","0"

Hi all, I have two vectors (columns) called "efinal" and "efinal 2". I want to plot them on the same plot and "draw" a shaded area beween the two lines using function polygon I have tried all but I don ?t understand the polygon area, can you help me with examples? plot(efinal,type="l",ylim=range(min(efinal2),

Hi all, I´m using titt<- expression(paste("R con ventanas de 200 ", italic(datos))) And it works properly on a plot(...,main=titt,..) But if I want to add an improvement to avoid typing n on the plot so that n<-200 titt<- expression(paste("R con ventanas de ",n, italic(datos))) It doesn´t recognize that n is a "variable" and adds "n" letter

Hi, Prevously, I set up Office 2000 with out outlook and frontpage sucessfully. Aftert that, I installed OUTLOOK and Frontpage. they require Internet Explorer to run. When I tried to install IE6, it says 'A previous installation has pending work requiring a reboot. You need to restart your computer to complete that installation before run IE setup. Setuo will now close' How to fix

Dear Sir or Madam: This is an extension to a earlier post, about looping through several thousand files, and testing student's models against a different data-set, called rclnow, for "recall now". The problem is, that the instructor never specified to the students, what they should name their "lm" object. So what they created was: "arbitrary variable name"

Hi, I have finally installed TeachingDemos trough zip file and installed on lbrary. One new question: I want to draw a line (like abline) on diagonal or the result of running a ols. How can I do it. On the other hand, I want to mark the length on each sub plot y axis. It is possible? My function is sca<-function(){ z2<-read.table("Ase.txt",header=T)

Hi I used write() the other day to save some results. It seems that write() does not record the full precision of the objects being written: > write(pi,file="~/f",ncolumns=1) > pi.saved <- scan("~/f") Read 1 item > dput(pi) 3.14159265358979 > dput(pi.saved) 3.141593 > pi-pi.saved [1] -3.464102e-07 > This difficulty was particularly difficult to

Hi all I want to apply different colors on a simple plot: If I type par(br="gray") before a plot it puts all the image in gray but (imagine I run a simple plot) want to let the centrall box (where the dots are plotted) in white or image in lightblue. Can anyone guide me to apply this second step (make the box where the series are plotted in different colours). Thanks in advance.

I imagine I make a function whose results are a Matrix Z How cn I save in a txt or excel file the result of apply my function? something similar to save Z.txt. Thanks in advance. [[alternative HTML version deleted]]
