similar to: modify tick labels in 3D GAM plot

I am using the mgcv package to develop vis.gam plots and having trouble figuring out how to relabel the z-axis (image attached). It is currently labeled as "linear predictor," but I would like to change it to a different name. Currently I am using this code: vis.gam(model1,theta=320,ticktype="detailed",color="gray",nCol=12, zlab="BCS") However, when run

My question is related to plot( ) in the mgcv package. Before modelling the data, a few predictors were transformed to normalize them. Therefore, the x-axes in the plots show transformed predictor values. How do I back-transform the predictors so that the plots are easier to interpret?

Hi R-listers, I am having trouble with persp plotting and I hope some knowledgeable person can help me. I have searched the help files to no avail. I am sure there is a way of achieving this simple task. I thought in par maybe but that seems not to work for 3d plots. Maybe I have missed something. I read in ?persp that it expects increasing values for both my x and y axes, and a matrix

Hi, I have thought a lot about my problem and also posted it on stackexchange, the post can be found here: http://stats.stackexchange.com/questions/44276/how-to-plot-3d-gbm but I have got no useful answer, that's why I trry the last possibility, which is to ask you professional guys. I want to recreate the following picture with my own code, the picture can be found in my other post:

Hello, I have quite a simple problem that I believe can be solved quite easily. I have a dataframe as such: Symbol Date Time Exchange TickType ReferenceNumber Price Size 1 3:YMZ7.EC 12/03/2007 08:30:00 EC B 83916044 13387 9 2 3:YMZ7.EC 12/03/2007 08:30:00 EC A 83916045 13388 1 3 3:YMZ7.EC 12/03/2007 08:30:00 EC B 83916054

Hi, I am trying to specify four ticks (at 0,1,2,3 for the y axis) in a persp plot but the defaults overrule my specification and I obtain seven of them. Is it possible to gain full control over them in such a plot? Here is my code: matlines=matrix(c(1:7,3:9,3:9,2:8),nrow=7,ncol=4)

I am having trouble getting my facets colored with "concentric" colors by z level. This code give a fair representation of my problems dealing a real dataset cmtx <- matrix(, nrow=10, ncol=10) cc <- (row(cmtx)-5)^2 + (col(cmtx)-5)^2 cc #---------- [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [1,] 32 25 20 17 16 17 20 25 32 41 [2,]

I am having some trouble getting the persp() package to change the x and y axis on a 3d plot. It defaults to the [0,1] interval and when I try to change it I get errors. Example: This works: ------------ D <- c(1,2,3,4,5,6,7,8,9,10) M <- c(11,12,13,14,15,16,17,18,19,20) DM <- cbind(D,M) persp(DM, theta = 40, phi = 30, expand = 0.5, col = "lightblue", ltheta = 120,

Dear R-users, I'd like to plot a three-dimensional surface and at the meantime I'm using an array. I would like to have the values of my first matrix in the heights of the plot and the colors of the single facet taking into account the second matrix. I hope that the next code will help all of you to understand better my issue, Thanks in advance, Giancarlo ############################ ##

Hi the list, I write a short function to draw lines in 3D, showing then turning. At some point, I add "delais" to slow down the rotation. So two questions: 1) I try to find a library to draw animate lines in 3D but I did not find. That surprise me since it is very simple to do. Did I forget to look somewhere ? If it does not exists and I have to use my own function : 2) Is it

Dear Adrian Dusa, others, I've recently started to learn R in order to use the QCA package because i think it might offer what other QCA packages don't: possibilities for quite a few conditions and large n. However, can someone tell me approx. how much RAM i need to run QCA on set of +/- 400.000 cases and +/- 15 conditions? (or differently: how much time will it take with RAM of a

Hi All, I have a file with two columns, the first column has the names of the patients and the second column has the age. I am looking into creating an output file that looks like 1-10 10-20 etc Eric Chris Bob mat Andrew Suzan Where each column has the name of the patients in a given age category that is displayed in the header. For example in the output, the first

Hello Masters, wishing you all a great 2011 I was also going to ask if anyone knows a quick and efficient way to plot a regression plane (z~x*y). I have tried the regr2.plot{HH} function but it is only an educational tool and has poor graphical properties. I also tried to run the following script on a fictitious longitudinal problem, with poor results set.seed(1234)

Dear R users, Could somebody tell me why the grey color ramp is repeated in this graph, eventhough the ramp values go from 0 to 1? I must be missing something obvious, but I can not see it! z <- c(0.064329041,0.117243316,0.161565116,0.19923015,0.231642175,0.259835539,0.284571226, 0.038507288,0.094184749,0.140959431,0.180803984,0.215159105,0.245096084,0.271412845,

Hello Experts I have the following codes and data for 2 interpolation plots. http://www.nabble.com/file/7206/3d_plot_data.txt 3d_plot_data.txt data<-read.table("3d_plot_data.txt", header=T) attach(data) par(mfrow=c(1,2)) library(akima) interpolation<-interp(rr,veg_r,predict) persp(interpolation,theta = -45, phi = 30, ticktype = "detailed", nticks=4, cex=0.8,

Hi All. I have created two, 3-D, color graphs using persp(). Z values range from 1 to 100 on the first plot, and 0.5 to 50 on the second plot. I would like to keep the color range constant between the two graphs, rather than each graph showing the full range of colors. So the first graph should go from yellow to red and the second graph should go from yellow to orange. Below I present a

Hi, I am a new user of "R", I am trying to read my data in.. "Cervixhc.dat" used to be in a different directory, now it has been moved to "O:\E&s\APC cervix FINAL (YG,MC,MD)\Manuscript\Data", but when I ran the following program (in red) I got an error message "Error in setwd(dir) : cannot change working directory", and "Error in file(file,

Hi, I'm trying to use mars function in R to interpolate nonlinear multivariate functions. However, it seems that mars gives me a fit which uses only very few basis function and it underfits very badly. For example, I have tried the following code to test mars: require("mda") f <- function(x,y) { x^2-y^2 }; #f <- function(x,y) { x+2*y }; # Grid x <-
