I have the code below which gives me what I want for temp based on logvec but I was wondering if there was a shorter way ( i.e : a one liner ) without having to initialize temp to zeros. This is purely for learning purposes. Thanks. logvec <- c(TRUE,FALSE,FALSE,TRUE,FALSE,FALSE,TRUE,FALSE) temp<-numeric(length(invec)) temp[invec]<-which(invec) temp [1] 1 0 0 4 0 0 7 0 obviously, the

I have this problem: I have an Internet line input with variable speed. I have a max speed and a min speed: Vmax and Vmin. The speed is always changing between Vmax and Vmin. I want to share the actual bandwidth (you don''t not how much, you only know the speed is between Vmax and Vmin) for N clients. The bandwidth should be shared so nobody can get more bandwidth than the others.

Currently, I load the RData file then ls() and str(). But loading the file takes too long if the file is big. Most of the time, I only interested what the variables are in the the file and the attributes of the variables (like if it is a data.frame, matrix, what are the colnames/rownames, etc.) I'm wondering if there is any facility in R to help me avoid loading the whole file.

This series adds support for GM20B PLL's Maxwell features, namely glitchless switch and (more importantly) DFS support. DFS lets the PLL lower its output speed according to input current variations, making the clock more stable and allowing it to run safely at lower voltage. All GM20B additions are done in the last patch, which consequently ends up being considerably big ; fortunately, it

Hi, on my system (Linux 2.6.18.8 - ia64), if a domain write on the xencons before xenconsole is initialized the domain gets back what it wrote. This patch fixes this issue by making raw the pty slave very early. (I suppose it doesn''t happen with linux as a guest because it takes a little bit of time before writing to xencons).

Hello, I am very new to R and Time Series. I need some help including R codes about the following issues. I' ll really appreciate any number of answers... # I have a time series data composed of 24 values: myinput = c(n1,n2...,n24); # In order to make a forecasting a, I use the following codes result1 = arima(ts(myinput),order = c(p,d,q),seasonal = list(order=c(P,D,Q))) result2 =

Hello, I am hoping someone can help me with the following: I am applying the function "mle" on a single data set X n times, each time using a different set of initial values v[i] (i=1,...,n). The initial values are all finite. Two cases arise: A- For some sets of initial values mle is giving parameter estimates. B- For some other initial values, mle is reporting the following error:

I tried the following ordered logistic regression in R: mod1 <- polr(altitude~sp + wind_dir + wind_speed + hr, data=altioot) But when I asked The summary of my regression I got the folloing error message: > summary (mod1) Re-fitting to get Hessian Error in optim(start, fmin, gmin, method = "BFGS", hessian = Hess, ...) : the initial value of 'vmin' is not

We're working on integrating LLVM 3.1 and integrating our AVX improvements which we hope to send upstream. I am trying to make sure we do't lose functionality of performance. Somewhere between LLVM 2.9 and LLVM 3.1 a bunch of opcodes got removed from isTargetShuffle in X86ISelLowering.cpp. It looks like at one point isTargetShuffle got removed completely so it is very difficult to mine

Hi everyone, My question will probably seem simple to most of you, but I have spent many hours trying to solve it. I need to perform a series of sequential calculations on my dataframe that move across rows and down columns, and then repeat themselves at each unique 'MM' by 'DD' grouping. Specifically, I want to add 'DEPART' time (24 hr time) to 'TRAVEL'(minutes)

Hello, I am an absolutely beginner with regards to R, so forgive me for my potentially very stupid questions. I have been attempting to create recurrence plots using R. The data I am using is based on a mutually exclusive and exhaustive coding scheme with over 40 individual codes which can be assigned to 6 higher order categories. When I carry out the usual rqa command, my plot is pretty much

I have two variables in a data frame, I want to generate two additional variables. For every observations (i.e. every row), I want the first new variable 'min' to carry the minimum of the two existing variables, and I want the second new variable 'max' to carry the maximum of the two existing variables. I then want to sort the data frame by min and max, and delete duplicated rows

Hi, I have a question about the format of Theora bitstream header. It seems to me that there are differences between the specification[1] (version 2004 Oct 1) and its reference implementation in libtheora 1.0alpha3 released at 2004 Jun 1. I mean that... please refer to Section 6.2 'Identification Header Decode' in that specification[1] and the function

Hello all, been 5 years since I posted on this list, glad to be back :) I have a number of X-power Tigra 1kVA online UPS units. From some knowledgeable folks working for the local distributor, I learnt that from inside this looked like a Best 610 ups unit. Before, I had this UPS hooked via serial to my Windows 2003 server. For monitoring, some winpilot/upspilot software was also provided.

Hello I have a data base consisting of soil parameters, and tree species densities. The vcd (visualizing categorical data) package includes the ternaryplot function which plots the gravitation center of 3 prameters. I'd like to find a similar function for use with continuous data rather than categorical. Does anyone know of a function suitable for this objective? Thanks Steve

Dear Ladies and Gentlemen, I have several old, yet functioning APC Smart-UPS (Model 600LS, Part AP600I, Firmware 6JI, no EEPROM, from 1991). They are not supported by Powerchute any more. I run NUT 2.6.5-4 on Windows XP SP3. I use COM1 port with cable 940-0024C. The connection fails with APC Smart protocol driver 3.0 (2.6.3-3534:3540M), APC command table version 3.0 or higher - it works with APC

The tripplite driver was developed on a machine with a reliable serial connection, and inherited the assumption that the serial line connection would not drop, reorder, or fail character read and writes. This patch adds significantly improved failure mode handling and also does basic checks of data validity. There's also a few minor cleanups/beautification. I've tested this code on my

Hello. I have problem with connecting to APC SC1000 using NUT port for windows 2.6.5-6. Last working version is NUT 2.6.1-1. With the same config files it works well. c:\NUT\bin>apcsmart.exe -a SC1000 Network UPS Tools - APC Smart protocol driver 3.1 (Windows-v2.6.5-5-7-g72f380c) APC command table version 3.1 w32_serial_open (COM3) setting initial state on COM3 0000007C = w32_serial_open

below is an rfc-style bitmap of the initial theora header. I've checked it against the spec and the code in libtheora; please double check :) I'm posting it here for those implementing demux stages (which necessarily don't use libtheora), and hence offering it for the spec. A typical demux stage just needs to pick out the FRN, FRD and KFGSHIFT fields, without going through the whole
