Hi, everyone, I am green with R. Now I am working on a graphics projects. I have a dataset: ----------------------- a b c 1 228 83 6.69 2 274 83 7.36 3 320 83 8.86 4 366 83 7.36 5 412 83 6.81 6 228 129 5.58 --------------------- I want to draw a 3d graphic. I use the code __________________

Dear WizaRds, I would like to create a 3d-plot with persp(). I sampled 17 points with xyz-coordinates (real-life example!), representing the peaks of the whole plane with "zero coordinates" x=3,y=3,z=3. My intention is to show which entries are above or below the "zero" level with persp() on a nicely created grid. I also tried scatterplot3d(), but, alas, I am unable

Hi Does R have a function or has someone written a function to draw a 3d surface from a scatter plot of values using either ksmooth or locpoly. OR a transform function a that merges x relation z and y relation z to (x,y) relation z? I tried out scatterplot3d but it seems it would take a bit of work to get scatterplot3d to draw a curved surface. Lawrence

Hello, I have a problem in drawing a 3d graphic. I simplified the program to show you the problem. I have a text file with hundreds of entries in 3 columns. I scaned these columns with matrix(scan). Then, I transformed some datas. Now I have the datas in h,x,y. I created a new matrix to use persp . But I got an error. The reason is probably the same length of x,y,z. But what can I do the draw

Hi, *Warning: R newb here. * I've got a 3D scatterplot ( http://www.fleetwoodswoodworks.com/scatterPlot.jpg) which I want to drape in color, with the draped plane corresponding to the mean z values on the plot (similar to: http://www.fleetwoodswoodworks.com/draped3Dscatterplot.jpg). Does anyone know what package will allow me to do this? I used * scatterplot3d()* for my first plot. I've

This is really a question of how to program this *BETTER*. It works as I have done it, but is quite ugly. I want to do a 3d scatterplot of the upper triangle of a matrix, where the z-values are the values in the matrix, and the row and column indices are the y- and x-values. The complete (11 by 11) matrix is mmtop94.2. Here is my awkward code: mmtop94.2[lower.tri(mmtop94.2)] <- NA # Here i

Hello list. I very often need 3d scatterplots, and use scatterplot3D quite a lot. I am trying to modify persp() to plot scatterplots, and make use of the theta and phi arguments that persp() offers. I am having some difficulty passing the correct arguments to persp(). Here is my function so far. Much of it is copied from the persp() manpage. points3d <- function(x,y,z,

Hi, I'd like to (1) plot a perspective view of a 3D scatterplot, with a fitted (curved) surface; (2) have a "stick" from each point vertically to the surface. The latter helps one visualize where a point lies in 3D, relative to the surface. Is there a variant of the cloud function (lattice package) which might do this? As far as I can tell, the cloud function will

Hi Im working on my master thesis, I need to get a plot currents distributed over a surface. I have the data listed in a dataframe with the x coordinates, y coordinates and the value. Im using the persp function but I’ve not found out how to put the data into the z1 variable es <-read.table("RDatalog_pass_dev_1_wafers_1_8V.txt",header=T,sep="\t") x1 <-

Hi, I am doing my way on R, with much experimenting. So, I am trying to plot a 3d graphic ussing "persp" and entering a data set (attached) of UTM coordinates as x,y and a pH values as z. However when I try an error message comes out telling that increasing x and y values are expected. Jus ordering the first vector does not help, and, of course, order the first two independently

The curve() function plots an expression in x over an interval [from,to]. I am looking for a function that would allow me to plot a parametrized curve t -> x(t) where x is a vector in 2 or 3 dimensions. For example (cos(t), sin(t)) (a2D  circle) or (cos(t), sin(t), t) (a 3D helix). It seems that neither curve(), plot(), nor persp() are helpful for that particular problem. I bet I?m not the

Thank you for your replies so far. Sorry for bothering you again, but I'm still not able to get what I need as I don't understand all parts of the replies (just using R for easy things....). Is there a code for plane3d() like some of you sent me for points3d()? I was not able to get that out of the scatterplot3d package... What I can do is to get the x,y and z-range for the xlim,ylim and

Apologies in advance for the question. I am trying to draw a map of the US as a surface plot so that I would be able to drop bars on the different states (something like Uwe Ligges' scatterplot3d example 4). I am not sure where to start looking for such a beast. If anyone has any pointers, ideas, I will be grateful. TIA, Partha

Hi all, I've got at really basic Q for you all: How do I produce a 3D plot in R? Like the one in the screenshot on the R-project wab-page.

Hi, I'm new to R (and math ;) Would somebody please be so kind as to direct me in plotting a 3D sphere? I tried something in the lines of: #### y <- x <- seq(-pi, pi, length=pi*10) f <- function(x,y) { z <- sqrt(pi - x^2 - y^2) #z[is.na(z)] <- 0 z } z <- outer(x, y, f) persp(x, y, z, theta = 120, phi = 30) #### I've also tried: .... make.surface.grid(...) ..

I have been making simple functions to display regressions in a new package called "rockchalk". For 3d illustrations, my functions use persp, and I've grown to like working with it. As an example of the kind of things I like to do, you might consult my lecture on multicollinearity, which is by far the most detailed illustration I've prepared.

I have a large matrix and want to create a 3d surface of it. Suppose the matrix looks something like Matrix K: a<-c(1:1200) b<-c(rep(1:30,40)) c<-c(a+b^2) K<-data.frame(a,b,c) The vector values are not ordered (and repeat themselves as in b). Whenever I try commands like "persp" it wants ordered values. The only command that approximates what I

I want to plot some 3D points on top of the grid produced by persp(). On 2/22/01, Paul Murrell <paul at stat.auckland.ac.nz> wrote in R-help: > In S-Plus, persp() returns a value that can be used to transform 3D > locations to 2D, but this sort of thing is not (yet) available in R. But persp() does return something (in R-1.5.1): a 4x4 matrix which in the C code is called the

Hi all, Is it possible to draw line segments in a 3d space plot? I'm interested to draw the errors from an observed value to the regression plane, for a textbook example in an Intro Stats handbook for multiple regression. I used the scatterplot3d package to draw the regression plane. Many thanks, Adrian ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Adrian Dusa (adi@roda.ro) Romanian Social
