Well,  do you expect web authors to have a much lower rate of
typos than 1:770 ?
My limited experience on "google voting for spelling correction"
has rather lowered my expectation on webauthors' education in
orthography...

[Rd] qt for df < 1

[roger koenker]

I was experimenting yesterday with a binomial make.link option
for estimating student t binary response models, tentatively
called gossit, and I noticed eventually that the R qt function doesn't
like df < 1.  Vaguely recalling that Splus didn't seem to mind such
weirdness,  I checked on our soon to be defunct Splus6.2 and
sure enough, it produced plausible answers instead of R's NA's.
Of course, I have no way of judging the quality of these answers,
but I'm curious about whether someone has already looked into
this can of worms.

Re: [Rd] typo in `eurodist'

[Spencer Graves]

  I'm with Martin:  When I get the same number of hits for two 
spellings, I believe that both are acceptable.  When I get substantially 
different numbers of hits, I generally go with the one with the most 
hits -- unless the different spellings carry different meanings, of 
course.

  Example:  "gage" vs. "gauge" vs. "guage":  24e6 vs. 32e6 vs 3e6.  The 
last is a typo.  The first has a special meaning, though "gauge" is 
sometimes used in that context.  However, when discussing repeatability 
and reproducibility, I prefer "gage", because it's more restrictive and 
therefore seems clearer to me.

Well the help page has:

For 'qt' only values of at least one are currently supported.

and someone must have written that...

R does have pt for df < 1, so a temporary fix using uniroot() seems
doable.

Why not?: qt is the inverse of pt.

Note from the help page:

   df: degrees of freedom (> 0, maybe non-integer).  'df = Inf' is
   allowed.  For 'qt' only values of at least one are currently
   supported.

so, yes, it is known about.

Hmmm ... Using my Google's "Results ... of about xxx":


  Gibraltar 50,700,000 
  Gibralta  75,200
  Gibraltr 573
  Gibralar 836
  Gibratar   1,020
  Gibrltar 349
  Gibaltar   1,850
  Giraltar 530
  Gbraltar 352
  ibralter 576

I'm not proposing to get exhaustive about this, but a few further
experiments suggest that other specific typos are typically O(500)
in frequency:

  Gibralatar   589
  Gibrlatar618
  Gibrltar 349
  Gobraltar652


So -- if anyone can find a typo of "Gibraltar" which googles to
more than 5000 hits (excepting "Gibralta")?

Best wishes,
Ted.

[Rd] grid graphics gpar(fill) argument and jpeg device

[Florian Hahne]

Hi everybody,
I just notice a strange behaviour of gpar's fill argument when using 
non-postscript devices:
The default of the argument is transparent (according to get.gpar("fill")).
So as expected, the following code draws a nice red rectangle in the 
middle of my X11 or postscript device.

pushViewport(viewport(width=0.5, height=0.5))
grid.rect(gp=gpar(fill="red"))
grid.rect()

However, when plotting on  a jpeg device (or any other pixel device), 
the output of the above code is an empty (=white) rectangle. Obviously 
the second grid.rect() which should produce a transparent rectangle 
turns out to be filled white on the jpeg device. When I set the fill 
argument to NA, the second rectangle is transparent as it is supposed to be.

grid.rect(gp=gpar(fill="red"))
grid.rect(gp=gpar(fill=NA))

Is this a bug or a feature???
I'm using R version 2.2.0 on a SUSE 10.0 linux machine.

Cheers,
Florian

Re: [Rd] typo in `eurodist'

[Tony Plate]

I would be wary of taking frequency of misspelling as an indication of 
"correctness".

Witness the following Google counts:

Amateur (correct): 52,300,000
Amature: 2,800,000
Amatuer: 2,660,000
Ameteur: 619,000
Ameture: 941,000
Ametuer: 574,000

Here's a common misspelling at > %10

Collectible (correct): 26,900,000
Collectable: 4,140,000

More targets at
http://www.yourdictionary.com/library/misspelled.html

(BTW, one can find a list of "commonly misspelt wods" using Google :-)

Feature.  The top-level grid viewport (representing the entire device) 
takes starting values for things like text size, background colour, etc 
from the device;  from R version 2.2, this includes using 'fg' and 'bg' 
from the device for gpar(col) and gpar(fill).  This is so that if you 
start a device using something like postscript(bg="red"), the gpar(fill) 
for the top-level grid viewport will be "red".

The default 'bg' for PostScript is "transparent", but for jpeg the 
default 'bg' is "white".
