Hello there, could you please help to modify gpar() properties of a cell inside tableGrob() output. In the following example I want to have different color for one out of 4 cells require(gridExtra) z<-matrix(1:4,2,2) grid.draw(tableGrob(z)) The only way I found for now how to do it is to do something like this downViewport(current.vpTree()$children[[1]]$children[[6]]$name)

I'm working on a package to produce graphic displays of 2- and 3-way tables and need some help/advice on how to simplify the specification of a complex argument that gives the drawing details for each cell of the table. Prototypes of two functions, 'tableplot' and 'cellgram' are given below. The essential idea is that for a given table ('values'), the cells can be be

Hi, Please consider the example below. How can I manage to overlay the points the way I want in the second case? Thanks, Joh library(ggplot2) # Modify data to match "real" case myDiamonds <- diamonds myDiamonds[["clarity"]] <- as.character(myDiamonds[["clarity"]]) myDiamonds[myDiamonds[["clarity"]]=="I1","clarity"] <- 1

hi, I use xtable to convert data.frames to html tables. But when I use the print-command I always get the whole output printed even if I just want to save the html table into a variable; table <- print(xtable(CERAT), type="html") How can I suppress that output is printed? thanks!

Hi, I am wondering whether some of you have a pointer to an alternative. I am currently writing my thesis in Latex (several documents), well grown over time, I am sure many of you are familiar with the situation. Likewise I am doing the quantitative analysis with R, and again a lot of lines of more or less wellwritten code. The outputs are graphs (which one can wonderfully integrate as PNG objects

Hi, I am trying to create a set of dummy variables to use within a multiple linear regression and am unable to find the codes within the manuals. For example i have: Price Weight Clarity IF VVS1 VVS2 500 8 1 0 0 1000 5.2 0 0 1 864 3 0 1 0 340

I am trying to learn the gee function in R. So I try to generate some data and use this function. I have the following lines: ######################################## Gee # Generating lny=10+2*Si-Si^2+eta # eta ~ N(0,1) # Si ~ U(0,11) eta <- vector(mode="numeric",100) eta <- rnorm(100) Si <- vector(mode="numeric",100) Si <- runif(100, min=0, max=11) lny <-

Hi all, So my question is pretty simple, but unfortunately I have not been able to find a good answer after extensive google searches. I am trying to plot an "attractive" data table in R, such as: http://t2.gstatic.com/images?q=tbn:ANd9GcRjfTbTEUWlnb73wtUkY1mbQblWA-2EKEgvTLXGzkqUSpH4mWrk Such data tables are easily done in Excel, but I am trying to automate the entire process in R.

Folks - I've been using Dovecot for some time now, but have only recently upgraded to 1.0alpha4. I'm struggling to get my configuration right and I'm seeing some truly bizarre issues. My Setup: Solaris 2.8 / Thunderbird / Procmail / Dovecot 1.0alpha4 My mail setup is only for me, so Dovecot runs at an odd port and under my userID. All my mail is in my home directory, which

hi, I want html code via the xtable package. I have a data.frame and tried to use the print()-function. But I only get the data.frame printed - no html arround it. what do I have to change? thanks!

Hi: I get?a couple of warnings? when trying to download gridExtra: install.packages("gridExtra",repos=http://R-Forge.R-project.org) ?Warning: unable to access index for repository http://R-Forge.R-project.org/bin/windows/contrib/2.10 Warning message: In getDependencies(pkgs, dependencies, available, lib) : ? package ?gridextra? is not available I would like to download the binary

I have dose response data I have analyzed with the 'drc' package. Using plot() works great. I want to arrange my plots and source data on a single page. I think 'gridExtra' is the usual package for this. I could use plot() and par(mfrow=...), but then I can't put the source data table on the page. gridExtra provides grid.table() which makes nice graphical tables. It

Hi, Is there any way to get an expression into a data.frame, such that "grid.table" from "gridExtra" will plot it evaluated in the table body? The docu does it for the header, but is the body possible? Thanks, Joh

Hi, I need to aggregate rows of a data.frame by computing the mean for rows with the same factor-level on one factor-variable; here is the sample code: x <- data.frame(rep(letters,2), rnorm(52), rnorm(52), rnorm(52)) aggregate(x, list(x[,1]), mean) Now my problem is, that the actual data-set is much bigger (120 rows and approximately 100.000 columns) ? and it takes very very long

Hi, I would like to cut a vector of values in parts. Each part should have an equal number of elements. for example: x <- (rnorm(500)^2) now I want 5 vectors each with 100 elements. The first vector should include the 100 lowest values of x and so on (so that the fifth vector contains the 100 highest values of x). thanks for any help!

Hi, When using the aggregate function to aggregate a data.frame by one or more grouping variables I often have the problem, that I want the mean for some numeric variables but the unique value for factor variables. So for example in this data-frame: data <- data.frame(x = rnorm(10,1,2), group = c(rep(1,5), rep(2,5)), gender =c(rep('m',5), rep('f',5))) aggregate(data,

Hi, I'm using the gridExtra package to combine some graphs like in the arrangeGrob example. Each of the graphs has a title but they appear much larger than the overall combined plot title and left axis label. Does anyone know how I can control the style / size of the gridExtra labels? library(gridExtra) library(ggplot2) dsamp <- diamonds[sample(nrow(diamonds), 1000), ] p1 <-

Hi, is there a function or an easy way to convert a variable with continuous values into a categorial variable (with x levels)? here is what I mean: I want to transform x: x <- c(3.2, 1.5, 6.8, 6.9, 8.5, 9.6, 1.1, 0.6) into a 'categorial'-variable with four levels so that I get: [1] 2 2 3 3 4 4 1 1 so each element is converted into its rank- value / categorial-value (in
