How to plot multiple datasets
Good Morning,
I have 3 sets of data, all with the same horizontal axis but with varying
vertical input. I want to plot all 3 sets on one x-y plot. I can get 3
linear regression plots and 3 polynomial regression plots on the same chart
but I have not been able to get more than one set of input data on the same
chart. Can you help me?
Thank you for all that you do to provide R to the public.

Normality tests
I have a large amount of data which I break down into a collection of
vectors of 100-125 values each. I would like to test the normality of the
vectors and compare them. In the interactive mode I can test any one vector
using the Shapiro-Wilk test or the Kolmogorov-Smirnov test. My problem is
that when I try to write out the results to a file, the term output is a
mixture of alpha characters

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:

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.

Advanced Format Technology
While researching another issue unrelated to Syslinux, I found some
mildly disturbing news that affects Syslinux. As HPA stated back on
2009-06-04, hard drive manufacturers are pushing towards a 4096B
(4kiB; 4k) native sector size. They're calling it "Advanced Format
Technology". It appears that WD (Western Digital; WDC) is the first

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

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, problem and solution?
Running R 1.6.1
Linux Slackware 8.1

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:

where fields$lengths is a vector of column widths, 28 to be exact. The data
are a mix of character, text, and factor variables.

Read.fwf
Dear List
I have a fixed width file with variables of varying width. The help is
pretty transparent for this feature, but I can't seem to figure out how
I can make effective use of the package with my data.
In my dataset, the first 80 columns are of width 1 followed by other
variables with width larger than 1.
I think the correct way to do this, by brute force, would be

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

reading fixed width format data with 2 types of lines
Hi,
I know how to read fixed width format data with read.fwf, but suddenly I need to read in a large number of old fwf files with 2 types of lines. Lines that begin with "3" in first column carry one set of variables, and lines that begin with "4" carry another set, like this:

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 :)

I love the option to not automatically convert strings into factors,
