Importing data with a header row using read.delim, one variable should be named @5HTT but it is automatically renamed to X.5HTT, presumably because the "@" is either unacceptable or misunderstood. I've tried to find out what the rules are on variable names but have been unsuccessful. I'll bet someone here can tell me where to look. Maybe it's hidden away in here

(Repeat of previous HTML version) Hello all, I am a new R user and I have finally imported my data using >read.delim("Filename.txt", header=TRUE) after some difficulty, by changing file directories (a hint to anyone who might be stuck there). However, I am now stuck trying to use my data. When I try to use data.frame("filename.txt") it tells me object not found, which

Hi, I am trying to read a tab-delimited file into R (Ver. 2.8). The machine I am using is 64bit Linux with 16 GB. The file is basically a matrix(~600x700000) and as large as 3GB. The read.delim() ran extremely slow (hours) even with a subset of the file (31 MB with 6x700000) I monitored the memory usage, and found it constantly only took less than 1% of 16GB memory. Does read.delim()

I have asked a similar question before but this time the problem is somewhat more involved. I have the following data: case;name;x 1;Joe;1 1;Mike;1 1;Zoe;1 2;Joe;1 2;Mike;0 2;Zoe;1 2;John;1 3;Mike;1 3;Zoe;0 3;Karl;0 I would like to count the number of "case" in which any two "name" a. both have "x=1", b. the first has "x=0" - the second has

Hi, I am trying to runn a age-period-cohort model, but here is what I am having problem with, hope you can help me! This is what I am trying to do: sumzero_a<-((A-min(A))/5+1) - mean((A-min(A))/5+1) where A is my age variable (numeric, the mid-point of a five-year age group), but I got the following error: Error in min(..., na.rm = na.rm) : invalid 'mode' of argument I am pretty

Great R people, I have noticed a strange behaviour in read.delim() and friends in the R 2.7.0 version. I will describe you the problem and also the solution I already found, just to be sure it is an expected behaviour and also to tell people, who may experience the same difficulty, a way to overcome it. And also to see if it is a proper behaviour or maybe a correction is needed. Here is the

Hello, I would like to read sets of files within a folder, perhaps using recursive methods. Right now, I rename the files before import. It would be even better to do this without renaming files, without providing explicit filenames, perhaps by importing files based on chronology, and translating each filename into a header? Please excuse my ignorance, and help cure my clunky programming

I have loaded the foreign package and am still having problems with an import. I get a message that reads, unable to open file. Whe I try different files I get the same message.

Hello. I have grown accustomed to the .Data directory in S-Plus and so when I came to R I continued that behaviour by saving my workspaces at the end of each R session. So, I have saved workspaces in various directories where I have used R just as I would have had various .Data directories where I had used S-Plus. I have seen comments on the list, most recently from Prof. Ripley that they

Hi, I found an existing pass "CalledValuePropagation" that can solve the problem I raised a few days ago regarding the "callees" metadata ( https://groups.google.com/forum/#!topic/llvm-dev/yjtZVMH_aC4). Now I have difficulty in calling this pass in my own pass. In my own pass, I called "getAnalysis<CalledValuePropagationPass>()" and in the

Hello, I used read.xlsx to read in Excel files but for large files it turned out to be not very efficient. For that reason I use a programme which writes each sheet in an Excel file into tab-delim txt files. After that I tried using read.table and read.delim to read in those txt files. Unfortunately, the results are not as expected. To show you what I mean I created a tiny Excel sheet with some

Hi all Very simple question, im sure, but I cant find docs anywhere that tell me how to do this.

I have written a function which reads data from files using read.delim (). The names of these files are complicated and are built using arguments to the wrapper function. Since the files in question may or may not exist, I thought to enclose the read.delim() call in a try(): file <- <complicated expression> temp <- try(read.delim(file)) if(inherits(temp,"try-error")) {

Dear Rs: Hi, I am trying to read a big text file (nrows=243440, ncols=144). It seems the computational time of all the read methods (scan,readtable,read.delim) is not linear to the number of rows I want to read in: things became really slow once I tried to read in 100000 lines compare to 10000 lines). If I am reading the profiling result right, I guess scan wouldn't help either. My
