Hi, If I have an R object UUU, where the second element is U2, based on "g" column of my.table my.table of UUU is: mmm ggg gindex map Info aaa123 U1 1 1 1 aaa124 U1 1 2 1 bbb1378 U2 2 1 1 bbb8888 U2 2 2 0 bbb1389 U2 2 3

Dear R helpers,   I know this is a simple task, but I'm new to R and I'm still havind difficulties with the language. I want to create 30 vectors to be used in a simulation, each with 1 columm and 5 lines, of random numbers N(0,1). What I tried was this:   N=150 u2<-rep(1:150,0) u2<-list(matrix(0,5)) u2 for(i in 1:N) { u2[i]<-rnorm(5) } u2 ### also tried this: N=150

Dear all, I would like to solve the following problem, which can be done with optimal control theory or dynamic programming: max(x,y) a*u1+b*u2+c*f1(u2) s.t. 0<u1<x, 0<u2<f2(x,u2), x'=f3(u1,u2,x) which can be rewritten if optimal control theory should be applied as H=a*u1+b*u2+c*f1(u2)+lambda*(x') s.t. 0<u1<x, 0<u2<f2(x,u2) The maximum principle

Hi, in the code below, I am drawing 1000 samples from two beta distributions, each time using the same random number seed. Using set.seed(80) produces results I expect, in that the differences between the distributions are very small. Using set.seed(20) produces results I can't make sense of. Around half of the time, it behaves as with set.seed(80), but around half of the time, it behaves

Dear all, Suppose I have a very long expression e. Lets assume, for simplicity, that it is e = expression(u1+u2+u3) Now I wish to replace u2 with x and u3 with 1. I.e. the 'new' expression, after replacement, should be: > e expression(u1+x+1) My question is how to do the replacement? I have tried using: > e = parse(text=gsub("u2","x",e)) > e =

Dear all, I am using the function 'D' in the 'stats' package to perform symbolic derivation. This works very well and it is much faster than e.g. Mathematica (at least for my purposes). First, I would like to thank the development team for this excellent function. However, I run into trouble in some cases, particularly when I am to do some operations on long expressions

If this is posted elsewhere I cannot find it. I need to perform multiple integration where some of the variables are in the bounds of the other variables. I was trying to use R2Cuba function but cannot set the upper and lower bounds. My code so far is : int <- function(y){ u2 = y[1] z2 = y[2] u1 =y[3] z1 = y[4] ff <- u1*(z1-u1)*u2*(z2-u2)*exp(-0.027*(12-z2)) return(ff) }

Hi all, I have upgraded a test machine from OpenSuSE 11.1 to 11.2. I have found following bug: the server is a 2x quadcore intel box also 2x4=8cpu If you limit the dom0 cpu with dom0-cpus= [1-7]: - [xenwatch_cb] is running 100% cpu and makes var log entry every 65 sec BUG: soft lockup - CPU#X stuck for 61s! - xm commands not work - xend is dead if set dom0-cpus to 0 or 8: - everything looks

Hi, In grid 4.0, adding two complex units by `sum()` seems to give wrong results. In the following example, `u1 + u2` gives the correct result, but `sum(u1, u2)` also `sum(unit.c(u1, u2))` give the wrong results. ``` library(grid) u1 = 0.4*sum(unit(1, "inch"), unit(1, "mm")) u2 = 0.1*sum(unit(1, "inch"), unit(1, "mm")) u1 # [1] 0.4*sum(1inches, 1mm)

There are two users u1 & u2 in the cluster. Some files are created by u1, and they are read only for u2. Of course u2 can read these files. Later these files are renamed by u1. Then I switch to the user u2. I find that u2 can't list or access the renamed files. I see these errors in log: [2018-01-15 17:35:05.133711] I [MSGID: 109045] [dht-common.c:2393:dht_lookup_cbk] 25-data-dht:

Dear all, Can anyone take a look at my program below? There are two functions: f1 (lambda,z,p1) and f2(p1,cl, cu). I fixed p1=0.15 for both functions. For any fixed value of lambda (between 0.01 and 0.99), I solve f1(p1=0.15, lambda=lambda, z)=0 for the corresponding cl and cu values. Then I plug the calculated cl and cu back into the function f2. Eventually, I want to find the lambda value

Hi All I need some real help in using virt-install. I have a fedora8 o/s + Xen installed and wanted to have RHEL4 as the Guest Domain. I have mounted the CD1 of RHEL4 and wanted to install this as guest domain using virt-install and not able to do and seeking help. Please let me know if the parameters to virt-install are correct and if not please let me know the correct parameters. Contents of

Hi everyone, I am using R 2.4.1 on a MacOS X ("Tiger") operating system. In the last few day I was trying to estimate the parameters of a mixture of two normal distributions using Maximum Likelihood. The code is from Modern Applied Statistics with S (4th edition), chapter 16 ("Optimization"), the dataset is available under MASS in R. Unfortunately, when I tried out the

Hi. I have this this on a Odroid-u2 backing it up. Have the USB from the CyberPower SX650G plug in the Odroid-u2 and when I do a lsusb it looks like this: Bus 001 Device 008: ID 0764:0501 Cyber Power System, Inc. CP1500 AVR UPS The User's Manual list SE450G and SX650G. So I guess they would take the same driver. CyberPower web page has a driver but it's for i386 not ARM like

Hello everybody! I’m trying to define the optimal number of surveys to detect the highest number of species within a monitoring season/session. To do this I want to run all the possible combinations between a set of samples and to calculate the total number of species for each combination of 2, 3, 4 …n samples events, so that at the end I will be able to define which is the lowest number of

Hi, I'm running smbd 2.2.8. I'm a little green when it comes to file locking with samba. I have two users that access a single data file on a FreeBSD box. It's a moneydance data file and obviously it gets messed-up if two users are writing to it at the same time. Is there a way with samba to stop a second instance of the file from being opened, something like a "File In

Hello you, maybe you can help me with a performance problem i?ve when tagging mp3 files from a windows vista system where the files are located on a samba share hosted by a suse linux 9.3 (samba releases is 3.0.23). these are my performance relevant settings. # These settings are a suggestion for a local network. Cf. section # 'socket options' in the man page of smb.conf and socket(7).
