similar to: Assignment to variables fails to loop

Dear all, I am attempting to add row and column names to a series of tables (120 in total) which have 2 variable parts to their name. These tables are created as follows: # Create table indexes index <- expand.grid(year = sprintf("%04d", seq(1986, 1995)), month = sprintf("%02d", 1:12)) # Read in and assign file names to individual objects with variable name components

Dear R Users, I'm trying to use the reshape package to 'melt' my gridded data into column format. I've done this before on individual files, but this time I'm trying to do it on a directory of files (with variable file names) - therefore I have to also use the 'assign' command. I have come up against a couple of problems however and am therefore seeking advice... >

Dear all, I am trying to read in and assign data from 50 tables in an automated fashion. I have the following code, which I created with the help of textbooks and the internet, but it only seems to read in the final data file over and over again. For example, when I type:> table_1951 I get the same values in the table as when I type> table_2000 despite the values in the source tables

Hi Guys, I''m having serious troubles resizing a dialog with a ListCtrl. The ctrl will not resize horizontally no matter what I''m doing. I''ve attached a sample code below. Any help will be greatly appreciated, as I really like wxRuby :) I''ve also tried to copy from the example from listtest.rbw, but that also doesn''t seem to work. Another thing

Dear all, I am trying to use 'merge' within a loop, however, I receive an error relating to the 'by' argument of the command, as follows: > merge_year <- 1986 > > for (i in 1:10) { # Number of file pairs + assign(paste("merged_arunfek_", merge_year, sep=""), merge(x=paste("arunoff_",start_arunoff, sep=""),

Dear all, I have many csv files whose contents I want to change a bit en masse. So far, I've written code that can change them in a for loop, like so: # Subset of files in the folder I want to change subset = "somestring" # Retrieve list of files to change filelist=list.files() filelist = filelist[grep(subset, filelist)] for(i in 1:length(filelist)){ setwd(readdir)

Hi, I'm using read.table in a loop, to read in multiple files. The problem is that when a file is missing there is an error message and the loop is broken; what I'd like to do is to test for the error and simply do "next" instead of breaking the loop. Anybody knows how to do that? Example: filelist <- c("file1.txt", "file2.txt",

Hi, I've noticed every time someone does an rsync-request on my ftp-site (which also provides rsync as mirror method), rsyncd creates a filelist. This is a quite IO and CPU intensive procedure, especially for things mirrors like FreeBSD with lots of little files. I was wondering... is there a way to cache that filelist? Our mirrors are updated once, or twice a day, it could speed up

Dear all, I'm trying to read in a whole directory of files which have two variable parts to the file name: year and month. E.g. comp198604.asc represents April of 1986 - 'comp' is fixed in each case. Years range between 1986 to 1995 and months are between 1 and 12. Just to be clear, there are 12 files associated with each year: e.g. comp198601, comp198602, ... comp198612 through to

Hi All, I have a slight issue getting R to plot a series of tables automatically. Essentially I have a series of tables that I wish to plot. They are named on_2, on_3 etc. based on the file name when they were read in. I have filelist <- list.files() to give me list of the table names. I wish to plot each table, so I was thinking along some kind of for loop as below: for (i in 1:Number_Files)

After more than one hour of countless tries, I ask myself a simple question : On what items are plugins supposed to execute ? I''ve tried to create a filelist plugin which, for a page, displays all file in the same directory (a rather old school view of website, where each directory contains an entry point). But, whatever I try, my plugin code is never invoked, and my page content is never

I''m still trying to work into Ruby 1.9.2 and am now experiencing something that makes no sense to me. Using rspec 1.3.2 and rspec-rails 1.3.4 with rails 2.3.11 on ruby 1.9.2-p180, when I $ rake spec:models they all pass. When I $ rake spec:controllers they all pass. When I $ rake spec:views they all pass. But when I $ rake spec I get <path to

I have the following code fileList <-list.files(path = ".", pattern = "[^a-z].txt$", all.files = FALSE, full.names = FALSE, recursive = FALSE, ignore.case = FALSE) for (x in 1:length(fileList)){ fileLines <- data.frame(read.table(fileList[x])) print(string) } the lines of the file all have the following format...

Hi, As a gentoo-user i frequently run the emerge sync command, which in turn does a rsync with the mainserver. The 'problem' is that the portage directory tree contains about 19.000 directories and 96.000 files. So building the filelist takes a pretty long time, because of the many disk accesses that are neccesary. On the server side the disk-io problem is probably less worse since

Hello, I am currently taking a statistics course and we are to do a project producing a graph using multiple input files. In R, I'm trying to build a filelist based on a pattern. For some reason, if I do the command interactively and not assign it to an array variable I get what I thought I should, but if I do this inside my R program it chops off some file names and thinks there are two.

I've done this before, but when I tried the same thing this time, it didn't work. I'm using R 2.4.1 on windows. I have 6 data frames that I want to include in a package I am building. Instead of making users issue six different "data(...)" commands, I want to wrap them all up in one file so that users issue one "data(...)" command and have access to all six data

There is no error - it just hangs indefinitely until some timeout period. This is what it looks like on the remote side: $

What is the error? I assume you know that with that syntax the filelist.txt is local rather than remote.

Hello, we have 80 text files with matrices. Each matrix represents a map (rows for latitude and columns for longitude), the 80 maps represent steps in time. In addition, we have a vector x of length 80. We would like to compute a regression between matrices (response through time) and x and create maps representing coefficients, r2 etc. Problem: the 80 matrices are of the size 4000 x 3500 and we
