Hi, I'm trying to copy the first row of one data frame to another. This is the statement I am using : df2[1,]<-df1[1,]; I have printed them out separately: df1[1,] = A C D E F But after copying: df2[1,] = 96 29 88 122 68 Why isn't it copying? They are both data frames, and "as.character" isn't working either. Thanks for your input :) [[alternative HTML version

Hi everyone, I am having trouble understanding where I went wrong with my code. It seems to logically be "all there" but the output says otherwise. I know this is a bit long but I can't seem to find the errors so I would appreciate your help :) This is my program : files<-Sys.glob("*.rescount.txt");length<-length(files);* #selecting all files of a particular

Hi, I am trying to create a data frame using the dimensions of another data frame that I have input. This is the code I am using: tab is the data frame that is input. c.leng<-length(tab[,1]); r.leng<-length(tab[1,]); opdf<-data.frame(ncol=c.leng, nrow=r.leng); a<-1; while(a<=c.leng) { opdf[[1]][a]<-tab[[1]][a]; a<-a+1; } This is the error message I am getting: Error in

Hi all, I am Sahana. I am currently working on Libtheora for windows platform and very new to it. I am getting a lot of compiling errors. Since Libtheora depends on libogg and libvorbis i have added these as well to my workspace in VC++ 6. I have a doubt regarding the x86 and x86_vc folders described in the libtheora software.Since both these folders have the same set of files which one do we

I'm having difficulty finding a solution to my problem that without using a for loop. For the amount of data I (will) have, the for loop will probably be too slow. I tried searching around before posting and couldn't find anything, hopefully it's not embarrassingly easy. Consider the data.frame, Data, below Data Sub Tr IA FixInx FixTime p1 t1 1 1 200 p1 t1 2

Hi Everyone, I have a 2-dim data.matrix(e.g., table1) in which row1 specifies a range of values. row2 - rown specify the number of times I want to replicate each corresponding value in row1. I can do this with the following function: rep(c(table1[1,]),c(table1[X,])) #where X would go from 2 - n. Now, I can do this manually by changing the values of X and save each resulting array/vector in

Hi everyone, I am trying to use the values from every cell of the data frame in a further calculation. This is the code that I am using to catch every element of the data-frame. while (a<=10) { while (b<=10) { n<-as.numeric(df[a,b)]; ...; } } The problem is that when I print out 'n' I get the following errors : "NULL" (if printed without as.numeric), and

Dear r-helpers, plot(all.effects()) uses trellis for its output, and often produces several effect plots in a layout. Can anyone tell me how to set the arguments to plot.effect which default to row=1, col=1, nrow=1, ncol=1, more=FALSE so that I can plot multiple effect plots on one layout? I was hoping that a call like last <- rep(c(TRUE, FALSE), c(3, 1)) lay <-matrix(c(1:4,), 2, 2,

I have never encountered anything like this before, so thought I'd post here and see if anyone can help. We have a java application that sends out notification emails to end-users. The body of the email is some boilerplate text and HTML that is pulled from a database. When the emails are received there are random instances of " !" (that's a space and a bang symbol) inserted

Hi all, I am whitening my data: # code begins N <- 300 M <- 2 x <- matrix(data=rnorm(N*M, 0, 3)-10, ncol=M, nrow=N) y <- matrix(c(1,-2,-2,1), ncol=M, nrow=M) z <- data.frame(x %*% y) colnames(z) <- c('x','y') par(mfrow=c(1,3)) plot(z, pch=5, col="blue") whiten <- function(x) { (x-mean(x))/sd(x) } zz <- transform(z, x=whiten(x), y=whiten(y))

Hello :) I'm just starting out with R and would appreciate your help with a couple of problems I am running into. I have used Sys.glob to get a list of all filenames having a particular file extension (in my case, *.txt) I would now like to use this list in the following manner: I would like to use each filename from the list and open that file into a tab separated matrix and proceed. How can

I guess this has a simple solution: I have matrix 'mat1' which has row and column names, e.g.: A B C row1 0 0 0 row2 0 0 0 .... rown 0 0 0 I have a another matrix 'mat2', essentially a subset of 'mat1' where the rownames are all in 'mat1' e.g.: B row3 5 row8 6 row54 7 I want to insert the values of matrix mat2 for column B (in reality it could be some or

HI, I'm looking for a function that does the same as deal() in MATLAB, i,e, for an array x[1 2 3] [a,b,c]=x; such that a=1, b=2, c=3 Does R have any functions similar to this? [[alternative HTML version deleted]]

Hi,All.Sorry for the group mail. I recently met a question and I have struggled on that for a while but failed to found the solution.

Hi! This is my first time posting. I've read the general rules and guidelines, but please bear with me if I make some fatal error in posting. Anyway, I have a continuous response and 29 predictors made up of continuous variables and nominal and ordinal categorical variables. I'd like to do lasso on these, but I get an error. The way I am using "lars" doesn't allow for the

Hi, I am trying to create unique filenames for my output text file. The idea is that I would like to append a string to ".zsc.txt" so that all my files are uniquely named but with a similar format. I have tried adding the string variable to ".zsc.txt" while creating the output file name, i.e. write.table function, is what I have tried using : write.table(x,

Hi, I'm using R to do a series of calculation and I have gotten several warnings that say "NaNS produced". Whatever I could read on line gives me an idea that this warning is produced when the number is use is a negative log or otherwise mathematically problematic. I'm getting this error while using factorial() and gamma () on strictly positive numbers (always greater than zero).
