similar to: Can I scale the labels in a 'persp' graph?

Hi all: I need to 3D graph using 'persp', but I need only to draw the axes of the graph, not data. Can anybody help me? Thank you in advance. /salva

hi all: ecdf() is the empirical cumulative distribution function, but I need the INVERSE cumulative distribution. how can I calculate it? thank you in advance /salva

Hi all, I need an R expression, expression(....) to get the follows Latex code: $P^\uparrow_{SF}$. Imposible, for me!!. Thank you in advance /salva

Hello- I'm new to R, coding and stats. (Oh no.) Anyway, I have about 12000 data points in a data.frame (dealing with dimensions and geological stage information for fossil protists) and have plotted them in a basic scatter plot. I also added a boxplot to overlay these points. Each worked fine independently, but when I attempt to superimpose them with add=true, I get a different scale for

Dear All, The function curve() draws the graph of functions from R to R. Is there some homologous function to curve() to draw functions from R^2 to R? Thanks in advance, Paul

Hi all, how do I change the magnification of xaxis annotation? I need a smaller axis text size in some of my plots. I tried cex.axix=0.5 in plot(), but this doesn't work.

One of the things that DOES make a big difference for me is font-antialiasing (AA). (OK, maybe I am picky). Does anyone have experience/knowledge on that subject? What surprises me is that for a few fonts (BitStream Vera Sans, for instance), it is active, whereas it is completely absent for most others. Why is that? (BTW, I just found out that I get the best results so far for the new MS font

R'istas: I am trying to plot a marginal distribution on the plane behind a persp() plot. My existing code is: library(MASS) X <- mvrnorm(1000,mu=c(0,0),Sigma=matrix(c(1,0,0,1),2)) X.kde <- kde2d(X[,1],X[,2],n=25) # X.kde is list: $x 1*n, $y 1*n, $z n*n persp(X.kde,phi=30,theta=60,xlab="x_b",ylab="x_a",zlab="f") ->res Any suggestions are very

I've created a perspective plot using 'persp' in the graphics package. I'd like to add a second plane of z values to the existing plot, but I cannot seem to do this using 'persp'. Is there an analogue to 'lines' or 'points' for perspectives? Corey. corey.bradshaw at cdu.edu.au

R-sters: I'm interested in keeping data plotted in persp to preserve the wireframe look, I'd just like to change one of the lines drawn (in either the x or y direction) into a different color so that it stands out. Or is there some way to add a line (say, via lines(), or abline()) to a persp() plot at the designated x or y that would follow the z surface contour? I could add a line

I am trying to graph two planes on the same graph using persp(). I can only get one plane to plot at a time. Can someone explain how I can graph two planes on the same graph using persp? I've looked throught the documentation, but cannot find any references to appending a persp plot. Thanks. Sincerely yours, Mark J. Lamias Statistical Consultant

I have this data set that both x & y are ordered vectors of length 600 & 700 respectively; z is a 600 by 700 matrix whose entry z[i,j] is either a missing value (indicated by 'NaN') or a real number between 0 and 1. The contour function contour(x,y,z) gives me a blank picture. I guess the reason is that most of z-entries are missing, only less than 1% are non missing.

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

Dear R-devel mailing list, I am wondering whether the "theta" and "phi" parameters of the "persp" function in the graphics commands are named in error (the names seem to have been swapped). Also, in the documentation to "persp", reference is made to "colatitude" when the effect in the image is actually that of "latitude". Thank you,

How can I control de "wrap-around" color behaviour in the persp function ? I am using something like : persp(bb[1:100,2:97], col= rainbow(8,start=0.1, end=0.8))) Depending on the rainbow length value I get several "wrap-around" blocks of the selected color range...something that I wanted to avoid... My idea is to use the color in order to make a separation from a certain

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

someone sent in a question earlier about doing something in 3D so i took a stab at it purely for educational purposes ( i'm not even sure that I understood the question actually ). Unfortunately, persp gives me an error that I don't understand because it says "object y not found". I'm sending y in as a parameter to persp similar to what ?persp shows in one of oits examples

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,

Dear Devels, I'm not sure if I'm going the right way by mailing to this list. I have two suggestions regarding the persp function from the graphics package: 1. In the documentation of the persp function, it is said, that the "col" argument will ignore transparent colors. However, this is not true, if you use strings as color code - at least it works with HEX-code (eg. :
