comment.char in read.fwf (PR#1297)
Full_Name: Jeffrey Longmate
Version: Version 1.4.0 Patched (2002-01-23)
OS: Windows NT 4.0
Submission from: (NULL) (151.152.101.44)
In read.fwf, ... args are passed to read.table, as stated in the documentation.
However, passing comment.char in this manner is defeated by the call to scan
that precedes the call to read.table. The problem is that scan has a default

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.

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.

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.

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.

Write.fwf works from Mac, throws different number of row error in Windows
Hello,
I am having a problem with write.fwf in Windows. I wrote a code to ingest a
number of text files with weather data in them, process them, and then
output a text file with two parts: 1) a set of column names, 2) the
processed data table.
I wrote and tested the program on my Mac, and it worked fine. However, on
the windows machine, where I intend the work to be done, when I run the

Reading multi-line FWF data
I keep getting these fixed-width format (FWF) data files where variables
for a single subject are spread across multiple lines and each line has
a different format (apparently created with SAS or SPSS). To read them
I stole some stuff from `read.fwf' in base R and threw together the
function included below.
Please feel free to test this function with your own data and let me

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, :

issue with ... in write.fwf in gdata
Dear R-list
This is just message to inform that the there is an issue with write.fwf in the gdata library (from version 2.5.0 on). It does not seem to accept further arguments to write.table like "eol" as the help file indicates as it stops when executing tmp <- lapply(x, format.info, ...).
Great package though - I use it a lot except for this function :)
See example below.

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

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,

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:

read.fwf, perl on win
i just used read.fwf
(which calls perl)
and i noticed something.
i also have mat;lab installed on this machine,
and matlab also installs a version of perl,
but a different one.
additionally, matlab puts its bin directory in the system
path. so, if one does not canerully set the path,
r will call the matlab verion of perl,
and things won't work.
