Hi: I have made a lot of progress reading and manipulating large data files, thanks to the help of several of you. I am now stuck with writing the final file with the following error (see also the full transcript below): Error in as.matrix.data.frame(x) : length of dimnames[2] not equal to array extent I do not know what it means and could not find how to get around that in the manual nor

The example scene: I have a database with stats about each goal made by my soccer team. This database (a data frame in R) is organized in lines (goals) with a set of columns containing data about these goals (player name, tactic position, etc). For now, this database will be called "data.frame1". What I need is to feed this "data.frame1" with new information about my team

Hi, I am an R newbie and one thing I am having trouble with binding variables that I have created within one data frame into a new data frame when using na.omit(). To illustrate this problem I will give the example I am working on and the approah I have been using:- data.frame1<-filepath.... attach(data.frame1) #create a new variable using a function new.variable<-rep(1,length(weight3))

I am positive this problem has a very simple solution, but I have been unable to find it, so I am asking for your help. I need to know how to look something up in one data frame and add it as a column in another. If I have a data frame that looks like this: > frame1 ID score test age 1 Guy1 10 1 20 2 Guy1 13 2 20 3 Guy2 9 1 33 4 Guy2 11 2 33 and another frame that looks like this:

hello list, Can someone help me figure out why the following code doesn't work? I'm trying to but both Greek letters and subscripts into a tcltk menu. The code creates all the mu's, and the 1 and 2 subscripts, but it won't create the 0. Is there a certain set of characters that R won't recognize the unicode for? Or am I input the \u2080 incorrectly? library(tcltk) m

Hi: I am a very recent user of R 1.40 for MacOSX and went through the help files but did not not find the function that I am looking for. I have two comma separated files which I want to partly combine. File 1 has 49670 lines and 26 columns (separated by commas) and looks like this: ...

Hi, I'm looking to combine two data frames. Several of the columns are in common while the others need to be summed up. The apply functions and the merge functions don't seem to be working. I've included a basic example of what I'm trying to do below. Thanks! Sean data.frame1<-as.data.frame(matrix(c('winter','dredge','515',100,150),1,5))

I'm trying to do a linear discriminant analysis on a dataset of three classes ("Affinities"), using the MASS library: > data.frame2 <- na.omit(data.frame1) > > data.ld = lda(AFFINITY ~ ., data.frame2, prior = c(1,1,1)/3) Error in var(x - group.means[g, ]) : missing observations in cov/cor What does this error message mean and how can I get rid of it? Thanks! Pieter

Hi all, I have 20 data frames, named frame1, ... , frame20. Each data frame has the dimension 20x5. I need to build a function that calls out the observation in Row 1, Col 2 from all 20 data frames and places it in a vector of length 20. I have tried the following code: vect <- rep(0,20) for(i in 1:20){ vect[i] <- paste("frame",i,"[1,2]",sep="") } The

This is a follow-up to bug sent to days ago, which bounced from r-devel because the example was to large. Now example is smaller, and behaviour is as belo, EXEPT that r-windows not any more bombs, so main problem is "xpdrows.data.frame"??? By the way, how to debug this example under windows? debug() doesnt accept the functions used (.Primitive), and R wont run under gdb --- may have

I tried feeding in the 3 encoded frame in ONE BLOCK, and calling speex_decode() 3 times in a roll. Only the 1st frames came out perfectly. For the other 2, I got "corrupt" frame warning. I was supposed to get 38 bytes consumed each frame (narrow-band, VBR off). I tried speex_bits_remaining() to peek on the # of bits consumed, and got variable (clearly wrong)#s returned. But if I

Hello. I'd like to produce a simple pairs-like plot with two data frames - but not a traditional scatter-plot matrix - just multiple bivariate plots of data.frame1[i] vs data.frame2[i] ... In other words, given data frames X and Y, I'd like multiple plots on a page like: Y1 Y2 Y3 X1 X2 X3 Thanks in advance. -R

Hi I have two data frames that contains the same sort of data and I want do add them together to get one big data frame, anyone know how to do that? ex: data.frame1 A B C 1 2 3 4 5 6 7 8 9 and data.frame2 A B C 9 8 7 6 5 4 3 2 1 Would then become one big set: data.frame3 A B C 1 2 3 4 5 6 7 8 9 9 8 7 6 5 4 3 2 1 Thx for your help //Joel -- View this message in context:

Dear R user, I'm relative new and need some help / advise from you. I have organised my data in several frames, mainly because the data came from different sources. One common variable in all data frames is the day post transplantation. I would like to combine the data frame to one big data frame which contains all the data, however no duplicate rows should occour (only one row for one

I'm coming out with all the classic problems today ;-) Can anyone tell me how to change the column names of an already existing data frame? I've read the docs for ?data.frame and ?as.data.frame but can't figure it out. I want to make a new data.frame from some of the columns of an existing data.frame, but when I do that, the new data.frame columns have the same names as the old

Folks, Evo update on my 4.x worked just fine. 5.0 generated a bunch of parsing errors preceded and followed by a couple of I/O errors that appear related to an unavailable URL. I first figured corruption on my node, so I yum erased evo, its - connector and -webcal units. The data-server removal looked as if it might remove half my Gnome desktop, so I left it in place. Then I did a selective
