Zoom in and out while using Locator() in R -


i have xy scatter plot of many points define filament structures (imagine looking @ pile of sticks laying on ground, that's these plots like). using locator identify start , end of each filament. end result table of line segments defined 2 points in xy.

a simplified base version of code runs this:

n=1 numberoffilaments=5 xdata=rnorm(1000,mean=500,sd=100) ydata=rnorm(1000,mean=500,sd=100) clicks.table=c()       while (n<=numberoffilaments) {   plot (xdata,ydata)   clicks = locator(2)   = c(clicks$x[1],clicks$y[1])   b = c(clicks$x[2],clicks$y[2])   clickpoints = c(a,b)   clicks.table = rbind(clicks.table,clickpoints)   n=n+1 }

some of data sets have gotten quite large in regard total width of data in x & y in comparison length of filaments trying click on. makes hard me accurately click on start , end of filaments. able zoom in on plot view individual filament, click 2 points zoom out view whole pile again. typically use r studio if matters. thank in advance.

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
