ff for 64 bit R for windows gui?
Hi, folks:
I am running 64-bit R on a 64 bit machine under 64 bit Windows 7. I'd
like to try the package ff, but it is not clear to me whether the
current version of ff will work in a 64 bit environment. The windows
version is "compiled," which suggests that there is more than just R
p-code. Do any of you know whether the current compiled version of ff
will work in my

'ordered' destroyed to 'factor'
Defending the status quo misses the point that R *could* handle ordinal data with a fixed set of levels but actually *does not*. Although it would be useful. Even if this does not imply to handle any possible straw-man situations. Having data-types for nominal, ordinal, and interval-scale data is - in theory - one of the major advantages of S over SAS. But *having* without *handling* means: only

'ordered' destroyed to 'factor'
Hi,
It's been my experience that when you combine or aggregate vectors of factors using a function, you should be prepared for surprises, as it's not obvious what the "right" way to combine factors is (ordered or not), especially if two vectors of factors have different levels or (if ordered) are ordered in a different way.
For instance, what would you expect to get from

pre summary: mapping of colornames into hsv?
Hi Martin,
Great that you follow this. My original intention was to be able to
translate colornames to hsv because this would allow using colornames to cut
out a certain part of the colorwheel for colorcoding (HSV component H, see
my code below)
I think internally we might have colors represented as
Colornames, ColorIntegers, ColorHexcodes, ColorRGBs, ColorHSVs (ColorCMYs?)

Append tables
R Help:
I have read a number of tables into R with identical headings and I
would now like to make a single table that has all the data appended
under this single heading line.
for example:
t1 <- read.csv("f1",header=TRUE)
t2 <- read.csv("f2",header=TRUE)
all <- c(t1,t2)
#all is now twice as wide as t1 or t2 with the same number of row!!!!

New version of package ff
Dear R community,
ff Version 2.1.1 is available on CRAN. It now supports large data.frames,
csv import/export, packed atomic datatypes and bit filtering from package
'bit' on which it depends from now.
Some performance results in seconds from test data with 78 mio rows and 7 columns on a 3 GB notebook:
sequential reading 1 mio rows: csv = 32.7 ffdf = 1.3

New version of package ff
Dear R community,
Package bit version 1.1-3 and ff version 2.1.2 is available on CRAN and should be useful to handle large datasets.
It adds convenient utilities for managing ff objects and files (see ?ffsave) and removes some performance bottlenecks.
In case you experience unexpected performance problems with ff, here is a couple of recommendations based on FAQs:

R-alpha: some thoughts about factor()

Factanal fits
Greetings, all:
I am using factanal in R.
When I enter a matrix or a formula, the print method winds up with something like this:
Test of the hypothesis that 6 factors are sufficient.
The chi square statistic is 28.1 on 22 degrees of freedom.
The p-value is 0.172
But when I enter a covmat, the print method winds up with something like this:
The degrees of freedom for the model is 22 and the
