Vis5D interface package
Greetings,
Summary: Has anyone else started a package (or have code) with the
capability to write Vis5D-readable netCDF files containing
irregularly-spaced data?
I've recently put together what might be the beginnings of a (GPL'ed) R
interface package to the Vis5D volumetric visualization program
(http://vis5d.sourceforge.net). Vis5D is commonly used in the
atmospheric science and

Non-interactive sessions
Greetings,
Quick Summary: How does R function non-interactively? I can't print
graphics to an X11 window.
I set up what appears to be called a "noninteractive" R session using
the Perl code at the end of this message. Everthing seems to work fine
as written. I get a nice postscript file with my graphics.
However, I would like to display X11 R-graphics for the Perl-script

Any way to get read.table.ffdf() (in the ff package) to pass colClasses or comment.char parameters through to read.fwf() ?
Hi everyone, my apologies if I'm overlooking something obvious in the
documentation. I'm relatively inexperienced with the (awesome) ff package.
My goal is to use the read.table.ffdf() function to call the read.fwf()
function and pass through the colClasses and comment.char arguments. The
code below shows exactly what doesn't work for me.
If the colClasses and comment.char

Wish: change behaviour of header in read.fwf (PR#9252)
Hello!
In my opinion read.fwf()'s behaviour of header is not really useful. Say
I have the following data:
col1 col2 col3
123 123 123
a b
1234 12 1234
65.4 4.5
Now if I want to read this data into R I can not use read.table due to
missing fields.
read.table(file="test.txt")

Read FWF, problem and solution?
Running R 1.6.1
Linux Slackware 8.1
233MHZ AMD-K6 96MB RAM
Using read.fwf, I tried to open a fixed-width file that of about 4 MB residing
in the working directory, using the command below:
dat<-read.fwf("sc01aai.dat", widths=fields$length)
where fields$lengths is a vector of column widths, 28 to be exact. The data
are a mix of character, text, and factor variables.

Controlling widths in write.fwf()
Is there a way to handle the widths of values being written to a file
using wrtite.fwf() ?
For example, I used read.fwf(file, width.vector) to read a file. After
making the necessary data manipulation, I want to write the data to a
new file in the same width.vector format. Is there a way to specify
this?
Thanks in Advance

read.fwf; bug reports 8226 & 8236 (PR#8284)
It seems to me that the bug dealt with in bug reports 8226 and 8236
is still not fixed.
I obtained the revised version of read.fwf from the latest
R-patched and tried
try.it <- read.fwf("junk",w,header=TRUE,as.is=TRUE)
This gave the error
Error in read.table(file = FILE, header = header, sep = sep, as.is = as.is, :

skipping columns with read.fwf?
I have a file in fwf. It is rather large, about 40,000 rows and 40 variables (columns). I only need about 10 variables form the data set for the analysis at hand. Unfortunately, these 10 variables are not contiguous in the file, for example, the first is position 1-8, the next position 25-27, then 40.
Is there a way to read the selected varaibles that I need without reading in the entire data

Weighted Histogram
Greetings,
I'm having trouble finding a simple way to calculate a weighted
histogram where there may be zero raw counts in a given interval.
Given equal-length vectors of data 'data' and weights 'w', and breaks
(intervals) for the histogram, I calculate a weighted histogram as
follows (see MASS's 'truehist' for an unweighted histogram):

Bug (?) in read.fwf
Hi,
I'm trying to use read.fwf
temp = read.fwf ("Raw data.txt", widths = c (11, 21, 10, rep
(16, 6)) ,skip = 2, n = 2, stringsAsFactors = FALSE, strip.white = TRUE)
but no matter what I do the strings are turned into factors. I believe
it's the "n=2" parameter that causes the problem as it seems to work
without this. Am I missing something?
Thanks in advance,

Subsetting a data.frame -> Read in with FWF format from .DAT file
Hi there,
I am having trouble subsetting a data frame by a conditional via one column
(of many).
I read the file into R through "read.fwf," where I specified column widths.
Original data is .DAT. I then utilized "names" function to read in column
headings.
For one column, PRVDR_NUM, I wish to further amend the entire data set, but
only have PRVDR_NUM == 050108. This is

read.fwf doesn't work with header = TRUE (PR#8226)
Full_Name: Emmanuel Paradis
Version: 2.1.1
OS: Linux
Submission from: (NULL) (193.49.41.105)
read.fwf(..., header = TRUE) does not work properly since:
1/ the original header is printed on the console and not in FILE;
2/ the different 'parts' of the header should be separated with tabs
to work with the call to read.table.
Here is a suggested fix for src/library/utils/R/read.fwf.R:

data file - function write.fwf - library gdata
Dear R-list members,
I have a data file with thousands of lines (cases), where each line
contains the values of several variables. I would like to separate
these lines in small groups, with each group followed by a blank
line, to ease the visual inspection of the data in some situations.
I am writing the output files with function write.fwf in library
gdata, for correct column alignment.
