similar to: Fixed-point cos/acos

Hi all, I have to calculate an expression using acos -function. A strange result of acos appears *1. case with error* ss <- sin(10.74*pi/180)**2 +(cos(10.74*pi/180)*cos(10.74*pi/180)*cos(0*pi/180)) ss acos(ss) [1] NaN Warning message: NaNs produced in: acos(ss) *2. case without error* ss <- sin(10.7*pi/180)**2 +(cos(10.7*pi/180)*cos(10.7*pi/180)*cos(0*pi/180)) ss acos(ss)

Hello, I don't know if the result of acos(0.5) == pi/3 is a bug or not. It looks strange to me. Inaki Murillo

Dear R help I was hoping you might be able to show me how to write a loop function take would ccomplish this task. library(prob) { a <- sample ( 1:20, 100, replace=T) b<-sample(5:24,100,replace=T) } dd <- data.frame(a,b) dd # code piece I am looking for if(subset(dd,c(1,23,ordered=F))is found))( print subset) else( continue evaluating subsets) subset(dd,isin(dd,c(1,23), ordered =

When creating a VMWare client that is Cent OS 5, the default SCSI disk is not recognized by the installer. Any suggestions for getting a disk on a COS5 client? Possible alternatives: 1) IDE disk, seems to work fine, 2) ??. Follow up to choice 1, is there a performance hit? While I have you, what is the best choice for "Guest Operating System".? Choices include RHEL, RHEL 4, and

Is there any way to change COS bits for packets? There is a tos option on sip.conf, does asterisk change COS bits considering tos value? -------------- next part -------------- An HTML attachment was scrubbed...

You have it right, for 1.2, use 'tos=', for 1.4 use 'tos_sip/tos_audio/tos_video'. ________________________________ From: asterisk-users-bounces at lists.digium.com [mailto:asterisk-users-bounces at lists.digium.com] On Behalf Of Al lists Sent: Monday, July 23, 2007 10:21 To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: [asterisk-users] Fwd: Asterisk and COS

Anyone else having issues getting the VB drivers to load on 1708? I keep gettting an "Error: unable to find the sources of your current Linux kernel..." message. I do have kernel-devel installed and I had no issues running 1611 on the same host. Thanks

I think you mean VirtualBox 5.1.26. And yes, there's some

Please note that you need to report your platforms (as per the posting guide), as the C function starts #ifdef HAVE_COSPI #elif defined HAVE___COSPI double cospi(double x) { return __cospi(x); } And AFAICS the system versions on Solaris and OS X behave the same way as R's substitute.

Hi everybody, I am reading the Lomb paper (Lomb, 1976) and I found an interesting equation, and I wish to resolve it using R. I am wondering if anybody has a hint. The equation is: Yis[i] = a*cos((2*pi/T)*(Times[i] - Tau)) + b*sin((2*pi/T)*(Times[i] - Tau)) ... (1) Where T and Tau are constants. I know the "Times" and "Tis" values (in fact these values come from a Time

Hello, the only thing I found to fit a sin/cos is s.th like lm(a~cos+sin) But this is not what I want. I have a magnitude which is sinusoidal with offset and it doesn't start at phi=0. The data is: angle<-c(0,10,20,30,40,50,60,70,80,90,100,110,120,130,140,150,160,170,180) Voltage<-c(-45.07, -45.24, -43.61, -40.78, -36.48, -30.92, -23.83, -15.95, -7.53, 1.06, 11.24,19.85, 27.00,

Hi, I am an R novice working with financial data. I am developing a portfolio strategy evaluation technique to back-test the performance of our screens; checking how the screened stock would've performed over the period in question. I am using quantmod in R to download the historical data from yahoo and then analyzing it using PerformanceAnalytics. My problem is that, as our screens are done

Hi, examining the network traffic with wireshark shows that asterisk does not set any QoS values at all. What do I need to do to make asterisk set QoS values (on Centos 7)? The wiki says to use vconfig to set QoS values[1]. What does the skb-priority need to be set to? How do you use vconfig on interfaces that are not VLAN interfaces? Is it generally impossible to set QoS values on

All: Are there any functions out there for selecting all the points in a region of a plot. I envision something like the identify() function except one could circle a cloud of points (and perhaps a vector would be returned of the same length as the points plotted indicating logical membership in the circled cloud). Perhaps someone has done something with the locator() function that would

I am trying to use if...else loop and have included a code snippet which I might like to expand. Maybe you could steer me in the right direction. library(stats) library(prob) { a <- sample ( 1:4,100, replace=T,prob=c(0.1,0.2,0.5,0.3)) b<-sample(3:6,100,replace=T,prob=c(0.2,0.2,0.2,0.4)) } dd <- data.frame(a,b) if (subset finds a vector) ( print that vector) (else
