Confidence interval on parameters from optim function
Hi everyone,
I have two questions:
I would like to get confidence intervals on the coefficients derived
from the optim() function.
I apply optim() to a given function f
> res <-
optim(c(0.08,0.04,1.),f,NULL,method="L-BFGS-B",lower=c(0.,0.,0.))
And I would like to get the p-value and confidence intervals associated
with

My second question deals with error message. I

[PATCH 2/3] drm/nouveau: manage nouveau_drm lifetime with devres
Make use of the devm_drm_dev_alloc() API to bind the lifetime of
nouveau_drm structure to the drm_device. This is important because a
reference to nouveau_drm is accessible from drm_device, which is
provided to a number of DRM layer callbacks that can run after the
deallocation of nouveau_drm currently occurs.

[PATCHv2] virtio_mmio: fix devm cleanup
Recent rework of the virtio_mmio probe/remove paths balanced a
devm_ioremap() with an iounmap() rather than its devm variant. This ends
up corrupting the devm datastructures, and results in the following
boot-time splat on arm64 under QEMU 2.9.0:
[ 3.450397] ------------[ cut here ]------------
[ 3.453822] Trying to vfree() nonexistent vm area (00000000c05b4844)

[PATCH 2/3] Make IRQ handlers typesafe.
This patch lets interrupt handler functions have their natural type
(ie. exactly match the data pointer type); for transition it allows
the old irq_handler_t type as well.
To do this it uses a gcc extension, cast-to-union, which allows a type
to be cast to any type within the union. When used in a wrapper
macro, it's a simple way of allowing one of several types.

Plot contour over filled contour
Dear R-users,
I haven't found a way in the searchable archive to overplot a contour
(lines) over a surface.
I have a (n,m) matrix that represents sea surface temperature that I
have plotted using image.plot(), filled.contour() or image(). I would
like to overplot this image with some contour lines of mixed layer depth
values(same size matrix). How can I do this?
Any help is appreciated,

Speex hardware requirements?
...mode that resembles "bytecode" (a 32-bit instruction
is executed using a 16-bit instruction). I got a feeling that the GBA
would need a FPU.
For more information on the GBA visit this info page:

and this development page: http://www.devrs.com/gba/

[PATCH] virtio_mmio: Set dev.release() to avoid warning
I think not. In virtio_pci_common, vp_dev is allocated by kzalloc so a
kfree is needed. Here vm_dev is allocated by devm_kmalloc which is
"automatically freed on driver detach" from the comment
(drivers/base/devres.c:769).
