Rers: I have some ecological data (stream velocity vs. % cover of submerged weeds) that shows strong evidence of a thresholding step-function, e.g. below some velocity, % cover ranges from 0% to 100% (with no apparent relationship to velocity within this range of velocities), but above a certain "threshold" velocity, the % cover do...

...as “ACK!”? It has an ill- deserved nod to NeXT, even. (Completely the wrong language, after all.) Core Compiler? Heh, I don't think that'd get past certain influential marketing departments. Nor is this a C API, but that didn't stop Core Data or Core Image, so y'never know. Veloce, schnell, rapido, rápide. Various translations of fast. Schnell is fun, but to an English speaker it has an imperative sense to it that makes it useless as an adjective, IMO. Veloce has a nice ring to it, though; that's Italian. Veloce Code? Velocicode? I think the kit-core-foundation-...

Hello. I've just started using R and am trying to figure out if the two codes snippets below have the same output gBest<-floor(runif(popsize,min=1,max=top)) velocity[i,j]<<-.4* velocity[i,j] + 1 * runif(1) * (pbestsVar[i,j] - popVar[i,j]) + 1 * runif(1) * (archiveVar[gBest,j] - popVar[i,j]) and for (i in 1:popsize) { for (j in 1:maxvar) { gBest<-sample(top,size=1) velocity[i,j]<<-.4* velocity[i,j] + 1 * runif(1) * (pbestsVar[i,j...

I have constructed a Trellis style xyplot. lengthf <- factor(length) xyplot(SLI$velocity ~ SLI$width | SLI$lengthf, layout = c(2,7), xlab = "Width (cm)", ylab = "Velocity (m/s^2)", col = "black") This produces a lovely little plot. However, the grouping factor(lengthf) isn't in the right order. My values range from 2-28 and the 2 graph on the botto...

hello all, I have a data frame and I want to create a column which assigns a letter based upon the value in another column. The data column has velocities ranging from 0 to 1000. So for example, for velocities between 0 and 300 I'd like to assign the letter "A" in the new column, for 300-600, "B" and so on and so forth. How would I do this? Thank you very much!

I use the function below to scan through a matrix and create mass action flux relationships: makeMassActionFluxes = function(sMatrix) { #Allocate a matrix with identical dimensions as the inputted stoichiometric matrix temp = matrix(nrow = dim(sMatrix)[1], ncol = dim(sMatrix)[2]) velocities = vector(length = dim(sMatrix)[2]) ## This series of 'for' loops scans the stoichiometrix matrix looking for negative integers. ## Once it identifies a negative integer it pulls the row name and exponentiates it to the ## appropriate stoichiometry, creating the flux expression. for...

Dear helpers I have two data sets saved as vectors (temperature and velocity). Now I need to "take out" a span of temperature and its corresponding velocity in the other vector. How can I achieve that? I tried to write a function,which takes a vector entry and then decides wether to delete the temperature entry or not and simultaneously doing so with same en...

Hello All, I am attempting to use the feather.plot function from the plotrix package to graph current velocity data as I have speed and direction. I let "r" be the first 10 rows of current speed data and "theta" be the first 10 rows of directional data in radians. I had tried this with 10 measurements, but keep getting the following error message: > feather.plot(r,theta,1:...

Think about slicing the cylinder along its axial direction to get a set of cross sections which are orthogonal to the z axis. For each section, I have a set of velocity readings, i.e. the data I would like to plot are in the form: v_11 v_12 v_13 ..... v_1n v_21 v_22 v_23 ..... v_2n ...................................... v_m1 v_m2 v_m3 ..... v_mn where v_ij is the velocity reading on the i-th position along z and...

...o, if we increase the rows_at_time to 1024 there are larger gaps between the 0's and actual data. The server is a sybase IQ database. We have tested it on a different database sybase ASE and we still get this issue. For example : We have the following query sqlString = "Select ActionID, Velocity from ActionDataTable" #where ActionID is of integer type and Velocity is of double type. connection = odbcConnect("IQDatabase"); #this database is a sybase IQ database sqlData = sqlQuery(connection, sqlString); sqlData$ActionID might be 1,2,3,4,5,6,....150, 0,0,0,0,0,0,0,....,0...

Hi, I am an astronomer and somewhat new to boostrap statistics. I understand the basic idea of bootstrap resampling, but am uncertain if it would be useful in my case or not. My problem consists of maximizing a likelihood function based on the velocities of a number of stars. My assumed distribution of velocities of these stars is: --------------------------------------------------------------------------- dmy=function(x,v,k,t)(k+1)/(v-t)^(k+1)*(v-x)^k --------------------------------------------------------------------------- where x would b...

Hi! I was hoping there was a tool which would let me do something like: #flax -o existing.flac --append mytune.flac To merge the 2 files! Also; is it possible to change the velocity/gain of a flac track ? I would love to know how! Regards, Frans

I am trying to get m"dot"s^-1 in a x-axis label for a publication ready graph. I can get ms^-1 with no problem, but I can't get the symbol for the "dot" to work. I am have tried the following: plot(x,y,xlab=expression(paste("Target Velocity (",ms^-1,")")),ylab="Passage Probability",ylim=c(0,1)) which works fine.

Hi Everyone, LLVM is a growing project, and many of us are very fond of it. :) LLVM is continuing to grow, both in maturity in specific areas and in scope of areas that it is applicable to. When we first started the project, we focused on the design of the intermediate representation. It is a strong design goal that the IR be a self-contained virtual instruction set, which fully describes
