similar to: Enhance Pairs Scatterplot Matrix

Hi, I am wondering if anybody has experience with scatterplot matrices where some (but NOT all) axis are transformed and the labels are nicely plotted. So far I looked into 1) pairs() 2) scatterplotMatrix() from package 'car' 3) splom() from packagae 'lattice' 4) plotmatrix() from 'ggplot2' I can see no easy way to get what I want which is: *) a scatterplot matrix of

Hello, I'd like to add custom labels to my pair() plot. These labels include math expression but they aren't correctly displayed... Further, I want that the boxes for the text.panel (diagonal) have an other background color (grey80). Is that generally possible? If yes how do I have to set it? What I've so far is: panel.cor <- function(x, y, digits=2, prefix="",

(I have checked the 2000 &2001 archives) Awhile ago, someone posted a function to plot a scatterplot matrix with the upper triangle containing plots (and maybe fitted curves?) and the lower triangle containing the correlation coefs. I have lost that code and would love it again if anyone has it. Thanks, Henry ***************************** Martin Henry H. Stevens HStevens at muohio.edu tel:

Hi, I am looking for a way to save the result of a function, e.g the lm()-function to a file and reload it afterwards again. I'd like to do that in order to minimize the used memory when running the function in a loop. The actual function I want to store is the evaluate() from the dismo package. I tried it with save() and load() but I am not sure if that is the way I should do it as I

Hi, it is easiest to explain what I want to do by an example: lets assume there are two factors/variables: A <- c(1,2,3) B <- c(1,3,3) Now I would like to generate a list of strings that should look like ("A1_B1","A1_B2","A2_B1","A2_B2"). So actually the string contains all possible combinations of A and B (separated by _). This should be also

Hello, I'm trying to pull off a certain graph using splom, and can't quite get my panel functions right. Basically, the equivalent using pairs would be something like this (using iris data set as an example): panel.corval <- function(x, y, digits=2, prefix="", cex.cor,col,pch) { usr <- par("usr"); on.exit(par(usr)) par(usr = c(0, 1, 0, 1))

Hi, I have a 1-column dataframe with rownames and I want to sort it based on the single column. The typical procedure that is recommended in diverse posts is to use order in the index. But that "destroys" my dataframe structure. Probabaly it is a very simple solution. Here is a short reproducable example: x <- c(1,3,51,2,34,44,12,33,2,8) df <- data.frame(x) rownames(df) <-

Hi, I have a dataframe and want to remove columns from it that are populated with a similar value (for the total column) (the variation of that column is 0). Is there an easier way than to calculate the statistics and then remove them by hand? A <- runif(100) B <- rep(1,100) C <- rep(2.42,100) D <- runif(100) df <- data.frame(A,B,C,D) # if want to conditionally remove column B and

Hi list. I was saving my modified pairs graphic using a custom panel from the R Graphics site, and I got an interesting difference in the final image when I save it as eps or png. This custom panel make possible to show at the left side of the pairs plot the p-value as symbol and the correlation r value with its cex proportional to the r value itself. Well, when saving as a png file

Good day! I'm having trouble changing certificate/keys for my dovecot(version 1.2.9). When I set up the server (unbuntu lts 10.4.4) I did it with a self-signed certificate. I can't remember exactly what I did, just that I followed the wiki and it worked fine =) Now I have to change the certificate because a friend bought an official one (from thawte) and I'm a bit stumped. As dovecot

The system is a Sun W2100z with 12 GB of ram, and R segfaults using only around 360 MB of

Hi Tanmay, >Does compiling speex API with DISABLE_FLOAT_API and DISABLE_VBR solve the >problem? I remember that this fixed the problem. But at that time I also needed VBR so this was not an option. As far as I know, it is related to some calculations that involve float denormals that cause the high CPU usage. Today I'm still using the following code before speex_encoder_init and

Hello, sorry i'm an R newbie and wan't to install ggplot2 on my ubuntu system. during installation i got the error warning: Warnmeldung: In install.packages("reshape") : Installation des Pakets 'reshape' hatte Exit-Status ungleich 0 Please, give me a idea, how can i fix this error/warning -- Jetzt informieren: http://mobile.1und1.de/?ac=OM.PW.PW003K20328T7073a

Hi, I want to create a pdf of my Man-pages from my package. Therefore I run in the terminal Rd2pdf on the package and a pdf of all the pages is created. After the titlepage there is the general package page, which includes "Description" and "Details" etc. Unfortunately after the Subtitle "Details" there is a pagebreak (and 3/4 white page) which I did not set

Hi, i want to plot empirical cumulative density functions for two variables in one plot. For better visualizing the differences in the two cumulative curves I'd like to log-scale the axis. So far I found 3 possible functions to plot ecdf: 1) ecdf() from the package 'stats'. I don't know how to successfully set the log.scales? Combining two plots is not a problem: plot(ecdf(x1))

Hi, I have two variables ranging both from 0 to 1 (n=500 each). Now I am interested in plotting them both in one plot (using ggplot2). So far I used ecdf() (from an example I found with google) to get values for the cumulatice distribution function which gives a relative curve. I also want to do the same plot but using absolute cumulative values instead of relative. Can that be done with ecdf or

Hi, I've kind of a tricky question, which I don't know how to solve yet: I get multiple dataframes loaded (readRDS) in a loop function. Each loaded dataframe contains two columns one with a var-name and one with a value. The rownumber (order) is very important as it is a value of the rank (1:x). A example with a similar looped structure: df1 <-

Hi, I have a dataframe with around 100 columns. Now I want to redefine some of the columns as factors (using as.factor). Luckily all the names of the columns I want to redefine start with "crast". Thus I thought I can use grep() for that purpose... ...I found an example for redefining a single column as factor but that is not working with multiple columns I get from grep()... what I

Hello, I already posted that on stackoverflow[1], but although it's crossposting, I think this question can probably easier to be answered by other R-users on this list, which maintain packages etc. I would like to make a package out of a function. The function is working in a script, but when I install and load it as library() I get an error. The example-function is: #Make generic function

I want to get data for a set of ticker symbols and compute the daily return of the adjusted close using quantmod, and then scatterplot returns using pairs(). The following gets data for the list of tickers: tickers <- c("SHY","TLT","SPY","IWM","GLD","IEV","ILF","EWJ","EPP","SAF","ASA")
