similar to: lattice: dots from xyplot to xscale.components

Hello! I'd like to have a function to draw correct grid while using log axis with xyplot from lattice package. Right now I have the following code inside of my panel function: lim <- current.panel.limits() v <- latticeExtra:::logTicks(2^lim$xlim, loc=1) h <- latticeExtra:::logTicks(2^lim$ylim, loc=1) panel.abline(h=log2(h), v=log2(v), col="LightGray") Is there an easy way

Hello! I?m having stacked data in a data.frame with 2 factors, ordered POSIXct, and actual value as numeric (as if for lattice::xyplot). I would like to calculate first difference using ?diff? function within corresponding subsets/partitions. Since data.frame is organized by factors and has sorted dates, it seems like "by" is a good candidate for the job. However it returns just a dumb

Good afternoon, I am trying to create a plot where the bottom and top axes have the same scale but different tick marks. I tried user-defined xscale.component function but it does not produce desired results. Can anybody suggest where my use of xscale.component function is incorrect? For example, the code below tries to create a plot where horizontal axes limits are c(0,10), top axis has ticks

Hi there, sorry for troubling everybody once again, I've got a problem rewriting Sarkar's function for rewriting the tick locations in a logaritmic way (s. http://lmdvr.r-forge.r-project.org/code/Chapter08.R): His example works for log 2 but I need log e (natural logarithm). My problem is that if I replace 2 with "e" (using paste()), I get the error message that the location

Dear people from the R help list, I have a question that I can't get my head around to start answering, that is why I am writing to the list. I have data in a format like this (tabs might look weird): John A1 1 0 1 John A2 1 1 1 John A3 1 0 0 Mary A1 1 0 1 Mary A2 0 0 1 Mary A3 1 1 0 Peter A1 1

Most of the WMMX instructions have MMX/SSE equivalents, plus there are a few other interesting functions. We have been thinking about doing WMMX optimizations of the various speex asm functions,

Hi helpeRs, I have inherited a set of data files that use the file system as a sort of poor man's database, i.e., the data files are nested in directories that indicate which city they come from. For example: dir.create("deleteme") for(i in paste("deleteme", c("New York", "Los Angeles"), sep="/")) { dir.create(i) for(j in

I work with the Microsoft Embedded Visual C++, and i don't have a linux machine with me. I need to have the best performance in order to run my application for the Intel XSCale with MMX. I don't know if i can compile for this processor with the best performance using the Microsoft compiler. I would like a help regarding how to get or build this .obj. Thank you. Cesar Bremer Pinheiro

Hi, Does samba require gawk, awk, perl, cc to compile? Or is it possible to just use the gcc compiler to build it. I want to build samba on xscale processor which has aminimal file system with native gcc compiler. It doesn't has perl or gwak etc. -Thanks, Rajesh

I'm developing a Personalized system of news audible for PDAs(Pocket PC and Palm OS), I have somes PDAs with differents processors(Samsung (2410) 266 MHz, Intel Xscale PXA 250 to 200 and 400 MHz, OMAP1510) with Pocket PC 2002 and 2003, and Palm OS 5 operating system. I offer myself to test any application of speex that runs in these machines, only you must send me the source code. Regards.

Hi, I have replaced most (but not all) of the float operations by integer operations, but it seems like the remaining ones take a long long time when emulated in kernel space (hence high system time). The other problem is that I don't have access to an ARM-based device (anyone wants to send me one?), so I'm doing all this blind... If you'd like to help, it can also accelerate things.

Hi, I'm not even sure what WMMX is, so I have no idea how to use it. For sure you would at least need to write some assembly. As for the current inline assembly parts (for the ARMv4 arch), you would need to convert them to VC++. It shouldn't be too hard, just push/load the registers at the beginning and then save/pop at the end. It's just the small macros (in fixed_arm4.h) that you

Just out of curiosity, has anyone profiled the difference between the floating point and fixed point implementations on processors with decent floating point support? (i.e. x86, PPC). Just wondering if it makes things better or worse there. -SteveK <p><p>On Nov 9, 2003, at 2:08 PM, Jean-Marc Valin wrote: > Hi, > > I just did some experiments and it seems like the high
