Hi I am trying to add density lines to multiple histograms created using R. I have managed to get all 18 lines on the last histogram in the series, however, i cannot figure out how to get each line appear on the correct histogram plot. I know in Matlab there is a hold function, is there something similar in R? the following is the code i have used to get mutiple plots and then add all the

Dear R-helpers, I'm working on mass spectra in randomForest/R, and following the recommendations for the case of noisy variables, I don't want to use the default mtry (sqrt of nvariables), but I'm not sure up to which proportion mtry/nvariables it makes sense to increase mtry without "overtuning" RF. Let me tell my example: I have 106 spectra belonging to 4 classes, the

hi I got the following error in 'evtree'. could u help pl. Error in if (var(mf[, nVariables]) <= 0) stop("variance of the denpendent variable is 0") : argument is of length zero [[alternative HTML version deleted]]

Hi how can print x-axis labels in 45 degree in boxplot() (or plot in general)? I can use las=2 to print in 90 degree, but it looks ugly. Is there a simple option to do 45 degree easily? Thanks John

Hi, ggplot/qplot is great - it has really helped me do some nice things. However, simple boxplot of different columns/variables is a bit tricky, because of (i think) qplot's generic Y conditional on X input form. Se below. # Some data: a <- rnorm(100) b <- rnorm(100,1,2) c <- rnorm(100,2,0.5) # normal boxplot of a,b,c boxplot(a,b,c) # Looks good library(ggplot2) # loads qqplot2 #

Hi, There seems to be a problem with setGroupGeneric() from package 'methods'. The symptoms are somewhat erratic, in the sense that small changes may lead to any of the following behaviours. 1.Package works without problems on Windows and installs on Linux but gives error when loaded with library(). 2.Package installs on both systems and gives error when loaded on any of them. 3.

Dear R-core team, I think I found a small inconsistency in the boxplot function. I don't want to post it as a bug since I'm not sure this might be considered as one according to the FAQ --- and this is not a major problem. Don't hesitate to tell me if I'm wrong. If you try to do a boxplot on a matrix and set the "at" argument to some vector different from 1:n, n is the

Hi, I'm trying to do a box-whisker plot of two columns of a data frame, a list of category names in one column vs. some numerical values in the other. The plot itself works fine, but only a few points of the x-axis ( the category names ) are labelled. I think that this is because the category names are too long. Is there any way to force R to label each x-axis value, preferably at a

Boxplot and bxp seem to have changed behaviour a bit of late (R 2.4.1). Or maybe I am mis-remembering. An annoying feature is that while at=3:6 will work, there is no way of overriding the default xlim of 0.5 to n+0.5. That prevents plotting boxes on, for example, interval scales - a useful thing to do at times. I really can see no good reason for bxp to hard-core the xlim=c(0.5, n+0.5) in the

Hi folks, I know, this is a fairly common question and I am really disappointed that I could not find a solution. I am trying to calculate Mahanalobis distances in a data frame, where I have several hundreds groups and several hundreds of variables. Whatever I do, however I subset it I get the "system is computationally singular: reciprocal condition number" error. I know what it means

I'm graphing a series of boxplots of grouped data inside a function that passes the data.frame, the names vector, and a title vector. Because both the data subset changes with each successive pass through the function, occasionally the names vector turns up with only one group to plot. This is an expected result. However, when the names argument in boxplot has only a single name, it

Dear all, I constructed this function called my.boxplot.stats by replacing fivnum() with quantile() in function boxplot.stats(). So I can try different quantile methods in bwplot(). The problem is I couldn't pass different values to the "type" argument to my.boxplot.stats, which in turn is an argument in bwplot(). Now I just have to manually change the "type" value in

Hi there, I would like to draw a scatter plot and fit a smooth line by loess. Below is the data. However, the curve line started from 0, which my "resid" list doesn't consist of 0 value. It returned some warnings which I don't know if this is the reason affecting such problem. Here I also attached the warning messages. Please let me know if there is a solution to fix this. Thank

 Dear Madame or Sir,I am having a problem in combining density-smoothed scatterplot matrices with a plot of kernel destiny estimations of each dimension plotted on the respective field of the diagonal.I have tried following approach using the package "sm" for the kernel density estimation, as well as "MASS" respectively:pairs(myTable[, 1:4],panel=function(x,y, ...){

Hi R-helpers, I have a data.frame with three columns (lots more reps though in each), like so: 'FOO' 'BAR' 'RESULT' 1 .01 75 1 .05 12 1.1 .01 100 1.1 .05 50 1.2 .01 75 1.2 .05 12 I am calling boxplot(RESULT ~ FOO:BAR, ...) This

Dear fellow R users, Keywords: Kruskal-Wallis, Post-Hoc, pair-wise comparisons, Nemenyi-Damico-Wolfe-Dunn test, coin package, oneway_test I am using the "oneway_test" function in the R package "coin" and I am obtaining results which I cannot believe are accurate. I do not wish to waste anyone's time and so if the following problem is rather trivial, I apologize, however I

Dear all, I am a total beginner in R, so sorry if this is the wrong place. I am using R 2.10.1 on a Mac (Mac OS 10.6.2). I have this small dataset : growth sugar 75 C 72 C 73 C 61 F 67 F 64 F 62 S 63 S I have no problem reading the table, or getting the summary, but if I try boxplot(growth~sugar, ylab="growth", xlab="sugar", data=Dataset), I have the following error :

Hi, I'd like to enable the scalarized conditional stores feature in the loop vectorizer (-enable-cond-stores-vec=true). The feature allows us to vectorize loops containing conditional stores that must be scalarized and predicated in the vectorized loop. Note that this flag does not affect the decision to generate masked vector stores. That is a separate feature and is guarded by a TTI hook.

Hi! We need to add a Conditional Forwarder to our Samba4 Domain. With the DNS Snap-In from Microsoft i can reate Zones, but if i try to add a Conditional Forwarder, i get an error message that this is not supported by the server. How i can add a Conditional Forwarder with Samba4 and Bind9_DLZ Backend? Thanks for help!
