similar to: 3D scatterplot, using size of symbols for the fourth variable

Hi all, I have a question about expression. In a figure I want to include the term D*obs with the star as as superscript and obs as subscript. I have even just tried to get the star to be superscript. The code I tried was text(Dstar+7,120,expression(paste({}D,^*))), but that doesn't work and I get a syntax error. I can't seem to find anything in the help files that explains it.

Dear all, I run a loop wrapped in try(), and for each of the rows where "try-error" is true I want to fill that row with NA (at the moment it is omitted). So I would expect to get a dataframe with 1000 rows some of which would be empty, but instead I get a dataframe with 995 rows. In this case missing 5 rows were omitted. Any suggestions? Thanks, Olga ----------------

Dear UseRs, I wrote the following function to use MLE. --------------------------------------------- mlog <- function(theta, nx = 1, nz = 1, dt){ beta <- matrix(theta[1:(nx+1)], ncol = 1) delta <- matrix(theta[(nx+2):(nx+nz+1)], ncol = 1) sigma2 <- theta[nx+nz+2] gamma <- theta[nx+nz+3] y <- as.matrix(dt[, 1], ncol = 1) x <- as.matrix(data.frame(1,

Hi all, I've been using the scatterplot3d function (from the scatterplot3d library) to create 3D plots. I was wondering whether there is anyway to group the points according to a particular group variable. For example I used the plot function as plot( factor( <GROUPINGVAR> ) , <PLOTVARS> ) to organise the results in a according to the grouping variable. I was wondering

Dear R helpers, I have a 3D scatter plot that I have generated from scatterplot3d (which looks great- thanks!) and I can see that the points in my graph fall in a plane. Following the example 5 from 3D scatter plot (below) I have fitted a regression plane. Now what I would like to do is a rotation so that my new co-ordinate system is about the fitted plane (by finding the normal to the plane

I have drawn a 3D scatter plot : library(mnormt) library(scatterplot3d) dat = cbind(rmnorm(3, rep(0,2), diag(2)), 1:3) scatterplot3d(dat) Now I want to do 2 things : 1 : In the Z-axis (i.e. height), I want to see only numbers 1,2,3, etc NOT, 1,1.5,2,2.5............. 2. I want to add two Horizontal planes at hight z=2 and z=3. Those two planes should look like "bottom" of that 3D plot

Greetings. I'm about to embark on my first big (to me at least!) R project, which will be to write a function to plot three-dimensional multiple correspondence analysis (mca) plots in a manner similar to scatterplot3d(). (plot.mca() plots only two dimensions, even though mca() will calculate more.) Before I do so, however, I would love to know that I'm not reinventing the wheel or any

Dear all I am running R 1.4.1 on a Linux box. I have tried to label data points in a 3-d scatterplot, but without much success. What I did was as follows: > scatterplot3d(x, y, z) > identify(x, y, z, row.names(Data)) When I tried to click on/near the data points, I either receive this msg: warning: no point with 0.25 inches, or some numbers in Data, not the row names, come up on the

I am attempting to fit a logistic regression plane to a 3-D scatterplot (which was generated using scatterplot3d). I've noticed that the help pages of scatterplot3d include a function titled "plane3d." However, when I attempt to use the function, I get the following message: Error: couldn't find function "plane3d" I've searched the archives and found no

I tried to run the following example from section 4.1.4 of the "Scatterplot3d - an R package for Visualizing Multivariate Data" vignette and got an error on the part that plots the regression plane: > library(scatterplot3d) > data(trees) > s3d <- scatterplot3d(trees, type = "h", color = "blue", + angle = 55, scale.y = 0.7, pch = 16, main = "Adding

Hey guys, I'm working on the S3D Benchmark and notice that CodeGenPrepare::OptimizeMemoryInst(...) in lib/Transforms/Scalar/CodeGenPrepare.cpp isn't scaling well. A whopping 99.3% of the compilation time for one file is spent in this function. The User Time for this compilation is 3166 seconds with a stock LLVM 3.1. If I disable the calls to OptimizeMemoryInst(...), the compilation time

Hello, I am trying to replicate example 4 in the package 'scatterplot3d': s3d.dat_data.frame(cols=as.vector(col(my.model4)), rows=as.vector(row(my.model4)), value=as.vector(my.model4)) scatterplot3d(s3d.dat, type="h", lwd=5, pch=" ", x.ticklabs=colnames(my.model4), y.ticklabs=rownames(my.model4), main="Conditional probabilities, Model 3") Nice! but,

hi, I am new to R and i have managed to create 2 3d scatterplots with R and Iwaswondering if there is a way to connect them. I was also wondering how i can add arrows to the plot similar to the 2d comment arrows()? -- View this message in context: http://n4.nabble.com/how-to-combine-2-3d-scatterplots-in-R-tp1461485p1461485.html Sent from the R help mailing list archive at Nabble.com.

Hi, How do you obtain the limits of the plotting region in a scatterplot3d plot? `par('usr')' does not seem to give sensible values, and that vector only has 4 elements (not the expected 6). Alan

Dear R users, I was trying to do a 3d scatterplot for the following set of datas: "obj" "time" "X" "Y" "1" "yellow" "333" "388.7" "492.3" "2" "yellow" "567" "388.7" "492.3" "3" "green" "621" "135.5"

Dear All,   using the example from the package scatterplot3d I created a 3d plot as follows:   x <-rnorm(500,50,2) y <-rnorm(500,5,1) z <-rnorm(500,6,1) scatterplot3d(x, y, z, highlight.3d=TRUE, col.axis="blue",col.grid="lightblue", main="scatterplot3d - 1", pch=20)   I would like to ask if anyone could help me with the following:   1. I would like to draw  a

Hi All. I'd like to programm a 4 dimensional chart in R. Acctually I wanted to solve that problem in Excel cause I had the data there. Here is a link of my actual problem description (there are some chart pictures as well).... http://www.mrexcel.com/board2/viewtopic.php?t=187336&highlight=stacked+column because I still couldn't solve that problem I came to R. The chart should be

Hi Experts, I am new to R, and was wondering how to do 3D linear regression in R. In other words, I need to Fit a 3-Dimensional Line to Data Points (input). I googled before posting this, and found that it is possible in Matlab and other commercial packages. For example, see the Matlab link:
