Hi, I'd like to merge mutliple dataframes from a list of dataframes by some common columns. The approach for simply merging 2 dataframes is working with: merge(df1,df2,by=c("col1","col2","col3"),all=TRUE) For mutliple dataframes in a list I try to use the merge_all command from the package reshape. The documentation states that the command takes a list of

I have a list of data frames: > str(data) List of 4 $ :'data.frame': 700773 obs. of 3 variables: ..$ V1: chr [1:700773] "200130446465779" "200070050127778" "200030633708779" "200010587002779" ... ..$ V2: int [1:700773] 0 0 0 0 0 0 0 0 0 0 ... ..$ V3: num [1:700773] 1 1 1 1 1 ... $ :'data.frame': 700773 obs. of 3 variables: ..$

Dear All, I am trying to create a empty structure that I want to fill gradually through the code. I want to use something like rbind to create the basic structure first. I am looking for a possibility to do an rbind where the columns names dont match fully (but the missing columns can be defaulted to either zero or n/a) (my actual data has a lot of columns). Please see the data frames below I

Hi R users, Can anyone share some example code using merge_all (from the reshape package) to merge 10 data frames into 1 file.

Hi all, I wish to merge 24 .csv files, each having a common identifier-column ("Name") and do two things: 1. Retrieve the common one's. [Analogy: while merging 2-dataframes, similar to using: merge (.... ,by="Name", all=FALSE) ] 2. Retrieve all, i.e., the union of the rows of 24 files. [again, somthing like: merge (.... ,by="Name", all=TRUE) ] On the web,

Hello r world, Does anyone know a function or package that can compute correlations between sets of XY coordinates? Thanks in advance for your help, Chris

Hello all, I apologize for a terribly simple question. I'm used to using Stata and am trying to `switch' over to R. I would like to recode a vector in a data frame when the value of it meets the following condition: if (dataframe$factor=='3'){dataframe$thevector<-(an arithmetic mean). What I would like to result is the creation of a new variable within the data frame for

Hi there, Moving this request for info over from an R-HPC-SIG list thread as the issue is less HPC than something that has bitten me as a result of trying to install HPC (read CUDA) R packages. Background to this is that I have both a Ubuntu host for a Tesla card that some researchers are looking to do CUDA-related R computation on, and a prototype, RHEL-based, cluster that is being used to

Hi, I just got a new computer with windows vista on it and I am having a problem using Tinn R. The problem occurs when I select a chunk of code and try to run it all at once using the "R send:selection (echo = TRUE)" button, I get this error: Error in source(.trPaths[5], echo = TRUE, max.deparse.length = 150) : object ".trPaths" not found Any suggestions how to fix this??

Hi, I've got a bunch of datasets (each has an "ID" column) that I'd like to merge into one big datasets. After a google search I found http://tolstoy.newcastle.edu.au/R/help/05/08/11131.html . However, I'm wondering if there is an easy way to do this as I've got about 12 datasets to be merged (all in the same format: an "ID" column and a "Frequency"
