[R] how to draw a 4d picture with density estimation?

I have 3 row data in the format as x,y,time I want to draw it as a 3d picture;x as x axis, y as y axis, the xy's density as z axis, the corresponding time as color. I have read the manual of R and failed, Since kde2d and bkde2d give grid data, this grid data cannot match its original time. Could an

[R] [help]how to estimate kernel density over samples from importance sampling

Dear all: First we run simulation through normal distribution, like p(x)=1/b, b is length of sample length, the properties of simulation we got f(x) has an unknow distribution. Through kernel density estimation we could get f(x)'s approximate distribution. Now I have run simulation through importan

[R] how to draw the legend about color from 3d picture

I have drawed a picture with persp, it's 3d map with different color, indicate different altitude. In gnuplot, the corresponding command 'splot' will generate a picture beside to indicate the relationship between color and altitude. But in R, how to draw it? I have read the manual of legend, but th

[R] periodicity validation

There is a series of data contains time in fixed step and energy varying with time, how to test its periodicity?In R, it seems there is no direct tools since I have search the R manual with periodic and I have not found any related topic. Thanks a lot __

[R] How to plot image of contour in percent?

I have searched this forum with keywords contour and percent, it only give one irrelevent result. My problems is how to plot contour in percent. In my figure, I have use kde2d to generate density of an array with two dimension point. Using image and contour could plot it. But the line contour gener

[R] Problem about plot scale

There are 4 sets of array, each have 2 dimension data:x,y. And these data comes from bkde. I tried to plot them in one figure, but details of some lines, like peak and where it locate, have diminished since one set of array have fairly high y value.And another array have lots of y value near zero,

[R] Problems:ticks overlap with each other

I have written the codes below. Unfortunately, the ticks generated by matplot A and matplot B overlap with each other. Does anyone have some idea to avoid it automatically? split_y=2.0e-4 layout(matrix(c(1,2),2,1,byrow=T),height=c(1,3)) par(mar=c(0.5,4.5,1.5,1.5)) x_row=max(row(x_m)) A:matplot(c(0
