similar to: NLME: Limitations of using identify to interact with scatterplots?

Hi I am following the model building strategy that is outlined in the Pinheiro and Bates book wrt including covariates but am having a problem with the plot. Basically I am using 4 covariates (1 of them is continuous) and 3 of them are fine but the 4th one is being shown as a scatterplot despite the fact that it is a factor. I have explicitly declared this to be a factor (pcat<-as.factor(pcat))

Hi This is the 2nd time I am posting this question as I never got a reply the 1st time round - apologies to anybody who might take offense at this but I dont know what else to do. I am struggling to split up the plots of the grouped objects in nlme in a usable way. The standard plot command generates plots for each group on a single page. When there are many groups however this does not look

I'm trying to treat a continuous variable as discrete for plotting multiple regression lines in a scatterplot as a function of the level on the moderating variable. In the example below, there is only one regression line plotted to the whole data. I would like a separate regression line for each discrete level of the moderator. The moderator is continuous, so I'd like to treat it as

Dear R users, I am using nlme to fit a pharmacokinetic model. The base model is parameterized in terms of CL, V1, V2 and Q. basemodel<-nlme(Conc ~TwoCompModel(CL,Q,V1,V2,Time,ID), data = data2, fixed=list(CL+Q+V1+V2~1), random = pdDiag(CL+V1+V2~1), start=c(CL=log(20),Q=log(252),V1=log(24.9),V2=log(120)), control=list(returnObject=TRUE,msVerbose=TRUE, msMaxIter=20,pnlsMaxIter=20,pnlsTol=1),

Hi I have found some postings referring to the fact that one can try and understand why a particular model is failing to solve/converge from the verbose output one can generate when fitting a nonlinear mixed model. I am trying to understand this output and have not been able to find out much: **Iteration 1 LME step: Loglik: -237.4517 , nlm iterations: 22 reStruct parameters: subjectno1

Hi, How can I plot two scatterplots on the same, one panel? I have two times series (price data for two goods) for the same period. Many thanks, -R [[alternative HTML version deleted]]

Hi, I am doing lots of scatterplots for my dissertation and to make the comparable, I would like to have equal x- amd - y axis. Can I specify their scale? Another question adresses overlay scatterplots. Having prae and post measures for each case, is it possible to have them in one graph with symbols or colors for prae and post. So scatterplot(bdiprae,mocoprae) and scatterplot(bdipost,mocopost) in

Hi, using scatterplot in 'car' package. There are 4 plots to be pictured together (ignore data used): library(car) par(mfrow=c(3,1)) ts.plot(rnorm(100)) ts.plot(rnorm(100)) scatterplot(rnorm(100),rnorm(100),boxplot="",smooth=T) # scatter with non-parametric fit problem is that the last one comes 'always' separate. Is there any way to solve it?? of course can use

Hello Everyone, I am new to R and need some help. I have a matrix of x,y,z coordinates that I would like to interactively plot in 3D and then using the cursor select points on the plot and have the coordinates sent to a matrix. I am using the rgl package to plot the data at the moment because it allows me to rotate and zoom. I also tried cloud and scatterplot3D. I am looking for a function like

I was able to make a scatterplot but ... 1) what does the "86" mean? The "86" shows up on the graph as well. > scatterplot (Shells/TotalEggs ~ Sector, data = data.to.analyze) [1] "86" 2) Also how do you change the Y axis title? I don't want it to read Shells/TotalEggs, instead I would like it to read Average Hatching Rate (%). 3) What does this error mean?

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.

R version 2.11.1 on WinXP How do I get 3 scatterplots with marginal boxplots (from the car package) onto a single plot?

Hi, When I plot a scatter plot, R automatically only gives the years on the x-axis. How can I make R also show the months on the x-axis? Thank you very much! [[alternative HTML version deleted]]

Dear R community, I have a scatterplot with multiple vertical ablines. I wish to color each interval between two ablines in a different color... Could you please indicate me how to do this efficiently? Thank you! Georg. ******************** Georg Ehret Johns Hopkins Baltimore [[alternative HTML version deleted]]

hi, i am need to plot two or more sets of data in a 3d scatterplot, each set with different color. i tried Rcmdr, and the 3d scatterplot facility, based on rgl. that is what i need. but i cannot seem to code different sets of data differently. any help will be very helpful. i tried scatterplot3d, but it is difficult to get the right angle in it. i need to be able to rotate the axes, and

I am attempting to classify pixels from a Landsat image by using their associated numbers in bands 2, 3, and 4 (It's from an assignment on classification). To aid me, I want to create a 3-D scatterplot using the "cloud" command. Due to my ignorance of the finer plotting functions, I am unable to display the scale on the three axes or to display the grid. My dataframe (RS)

Dear R users: I have a continuous outcome variable and four predictors, two continuous and two dichotomous. i would like to use the lattice plot to create scatter plots for the continuous predictors and boxplots for the dichotomous predictors. with 4 continuous variables, this is what i have been doing: trial = rbind ( cbind ( cimt$ant.mean, cimt$age, 1 ), cbind ( cimt$ant.mean, cimt$sbp, 2 ),

Hi everyone, i?m trying to graphically display distributions with r and i?m working with makrodata from the WVS. the command i?m using is > plot (Makrodata$v11, Makrodata$v12, xlab="Democracy Score Economist", > ylab= share religious people") i?m having an additional variable that identifies respectively labels the

Hello, I teach statistics and use R Commander for teaching. I have 2 students out of 169 that can't get scatterplots or plot to work. I have had them update packages, restart R/R Commander/their computers and even reinstall R/R Commander. One is using Windows 7 on a new pc and the other is a pc user (not sure the OS). They are both using R2.11.1 and R Commander 1.6-0. The data look like

Greets Folks, I've been wrestling with how to better control plotting of time data and just can't seem to see the right path. My dataset has thousands of points distributes across a number of years. I would like to plot the responses according to increasing time with nice boundaries - perhaps integer months - along the abscissa. However, the earliest time occurs mid-month and I
