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 > res$par 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) [ 3.460534] WARNING: CPU:

[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. (Some drivers now need to

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?

[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).
