r - Find largest 5 value less than 1, lowest 5 values -

-

i have large correlation matrix result in r - 30 items correlated against each other - array has 10,000 cells. want find largest 5 , smallest 5 results. how can this?

here's small portion - upper left corner - looks like:

               pl1         v3          v4         v5 pl1     1.00000000 0.19905701 -0.02994034 -0.1533846 v3      0.19905701 1.00000000  0.09036472  0.1306054 v4     -0.02994034 0.09036472  1.00000000  0.1848030 v5     -0.15338465 0.13060539  0.18480296  1.0000000

the values in table between 1 & -1 , if helps, being correlation matrix upper half above diagonal duplicate of lower half below diagonal.

i need positive 5 less 1 , negative 5 including -1 if exists.

thanks in advance.

you want find largest , smallest correlations , know not what, values came from. it's easy.

x<-matrix(runif(25),5,5) cor<-cor(x) l <- length(cor) l1 <- length(cor[cor<1])  #the actual high , low correlation indexes  corhigh <- order(cor)[(l1-4):l1] corlow <- order(cor)[1:5] #(if want view correlations cor[corlow] or cor[corhigh] works fine)  #isolate them in matrix can see came corhighview <- cor corhighview[!1:l %in% corhigh] <- na corlowview <- cor corlowview[!1:l %in% corlow] <- na  #look @ matrix target correlations sticking out sore thumb corlowview corhighview

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,...

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
