Hi R community,
I'd like to automatically create a number of matrices named for
elements of another list or matrix.
#I'm planning to deposit data into matrices named for plates in a platelist

Hi,
I'm fitting a standard nonlinear model to the luminances measured
from the red, green and blue guns of a TV display, using nls.
The call is:
dd.nls - nls(Lum ~ Blev + beta[Gun] * GL^gamm,
data = dd, start = st)
where st was initally estimated using optim()
st
$Blev
Please provide reproducible code which shows the error.
dd - structure(list(Lum = c(0.15, 0.07, 0.1, 0.19, 0.4, 0.73, 1.2,
+ 1.85, 2.91, 3.74, 5.08, 6.43, 8.06, 9.84, 12, 14.2, 16.6, 0.1,

Hi,
I am using SAM (from siggenes_1.2.11 package) method to select genes from
a microarray data set. After installing the latest R2.4.0 on my computer, to
my surprise the results are totally different from that calculated using
R2.1.1. Even the example code doesn't work the same way under
I would appreciate help trying
to set different plot types in a lattice plot with multiple responses e.g.
xyplot(y+fval~x)
but have y as points and fval as a line.
I have tried
xyplot(y+fval~x,type=c(p,l))
but this results in both plots having both types.
Thanks

Nice solution.
I believe that showing the decimal point is correct. It demonstrates
that the number is not an integer.

Since formatC is an implementation of the C-style
Use
distribute.type = TRUE
or
panel = panel.superpose.2.
as an argument to xyuplot. e.g. Using the builtin anscombe data set:
xyplot(y1 + y2 ~ x1, anscombe, type = c(p, l), distribute.type = TRUE)
# same
xyplot(y1 + y2 ~ x1, anscombe, type = c(p, l), panel = panel.superpose.2)

You must be thinking of some other language:
is.integer(1)
[1] FALSE

I meant that it demonstrates that the number is not an integer to the
reader, regardless of how it is stored. In the reporting of
measurements,
10
is interpreted as an integer, whereas
10.
is interpreted as a real, rounded to two significant digits.

Thank you for your rapid response.
This is reproducible on my system. Here it is again, with, I hope,
sufficient detail to properly document what does not work and what
does on my system,
But my original question, properly motivated or not, concerns whether
there is a way to use or adapt
