I am fairly new to R and would like help with the problem below. I am trying to sum and count several rows in the data frame yy below. All works well as in example 1. When I try to add the columns, with an NA in Q21, I get as NA as mySum. I would like NA to be treated as O, or igored. I wrote a function to try to count an NA element as 0, Example 3 function. It works with a few warnings,

Hi, I have a script which I source, which evaluates a changing expression call hundreds of times. It works, but it prints to screen each time, which is annoying. There must be simple way to suppress this, or to use a slightly different set of commands, which will be obvious to those wiser than I... Here is a simpler mockup which shows the issue: x = data.frame(rbind(c(1,2,3),c(1,2,3)))

Hi all, ########################################## dof=c(1,2,4,8,16,32) Q5=matrix(rt(100,dof),100,6,T,dimnames=list(NULL,dof)) par(mfrow=c(2,6)) apply(Q5,2,hist) myf=function(x){ qqnorm(x);qqline(x) } apply(Q5,2,myf) ########################################## These looks ok. However, I would like to achieve more. Apart from using a loop, is there are fast way to 'add' the titles to be

I'm trying to find a way to change the font size in a mosaic plot (the grid version, not the base graphics one). Here's an example to demonstrate: #Basic plot library(vcd) mosaic(HairEyeColor, shade = TRUE) #Bad first guess: this stops the default cell colouring, and doesn't change the font size mosaic(HairEyeColor, shade = TRUE, gp=gpar(fontsize=16)) #This successfully changes

I have a figure on screen with a legend. I want to copy this image to EPS, and use: dev.copy2eps(file="file1.eps", width=5, height=5) The legend that looks OK on screen doesn't look OK in the PostScript image: the text extends out of the box. I try adding a fontsize command: dev.copy2eps(file="file1.eps", width=5, height=5, pointsize=5) This options seems to

Hi List, I am trying unsucessfully to modify the fontsize of lables in mosaic: require(vcd) mosaic(Titanic, pop=FALSE, labeling_args=list(rot_labels=c(bottom=90,top=90), set_varnames = c(Sex = "Gender"), gp_text=gpar(fontsize=20))) #can't get it to resize text tab <- ifelse(Titanic < 6, NA, Titanic) # it works for labeling_cells labeling_cells(text = tab,

I'm not understanding something. I'm trying to add xlab & ylab to a balloon plot of a table object. From docs I thought following should work: require(gplots) # From balloonplot example: # Create an example using table xnames <- sample( letters[1:3], 50, replace=2) ynames <- sample( 1:5, 50, replace=2) tab <- table(xnames, ynames) balloonplot(tab)

I currently have a data frame whose rows correspond to each student and whose columns are different variables for the student, as shown below: Lastname Firstname CATALOG_NBR Email StudentID EMPLID Start 1 alastname afirstname 1213 *@uark.edu 10295236 # 12/2/2008 2 anotherlastname anotherfirstname 1213 **@uark.edu ## 10295236 9/3/2008 Xattempts Q1

I'm just starting to work with lattice graphics, and am having difficulty understanding how to control various graphic parameters (font sizes, etc.). [I'm actually using xyplot via plot.effect() in the car package, and would like to be able to set some global defaults.] I read ?xyplot and ?trellis.par.set-- which contains no complete list of parameters, just a reference to

Hi, i get error after using a data.frame with subset for "sqlSave". What can i do ? It seems that lines like this in a data.frame structure are after subset deleted and cause the error ? - attr(*, "variable.labels")= Named chr "CUSID" "Welle" "Arbeitgeberfavorit1" "Aktuelle Bewerbungssituation" ... ..- attr(*, "names")=

Hi! I'm new to this list and i could not find a way to search through the already posted articles, so please forgive me if this subject has been discussed before. Our security scanner stumbled over the IMAPs server i've set up recently using dovecot on a RedHat Enterprise 64bit Server. The security scanner found an error regarding a new SSL security leak named "BEAST". The

G'day all, I had a look at the GLM code of R (1.4.1) and I believe that there are problems with the function "glm.fit" that may bite in rare circumstances. Note, I have no data set with which I ran into trouble. This report is solely based on having a look at the code. Below I append a listing of the glm.fit function as produced by my system. I have added line numbers so that I

In an Sweave slide, I want to use sem::read.moments() and sem::specify.model(), which work by using scan() to read the following lines, up to the first blank line. However, Sweave throws an error: > Sweave("sem-thurstone.Rnw") Writing to file sem-thurstone.tex Processing code chunks ... 1 : term hide (label=arrests-setup) 2 : echo term hide (label=thurstone-data) Error:

Dear R Community, I tried to generate heatmap for a matrix of 1500 columns by 106 rows using the following R script: > pheatmap(tf.vs.DE.1.removeAllZeroCol, fontsize=3,border_color=NA) and got the graph (as attached Fig 1) Since the column labels appear very crowded, I tried to increase the cellwidth to stretch the graph horizontally. The idea was to show the graph section by section, but with

Hi, since lattice uses nested lists in various situations, it has had an unexported function called updateList for a while, which looks like > lattice:::updateList function (x, val) { if (is.null(x)) x <- list() if (!is.list(x)) stop("x must be NULL or a list") if (!is.list(val)) stop("val must be a list") xnames <- names(x)

Hello everybody, often I plot boxplots with different number of boxes (up to 200 boxes). I'd like to give every box a readable label on the x-axis. Therefore, I decrease the fontsize of the names and plot them vertical. But if you zoom into the plot (pdf) you will find an offset between the tickmark and the label - the label is shifted to the right. If you vary the box.count in the

First, here's the problem I'm working on so you understand the context. I have a data frame of travel activity characteristics with 70,000+ records. These activities are identified by unique chain numbers. (Activities are part of trip chains.) There are 17,500 chains. I use the chain numbers as factors to split various data fields into lists of chain characteristics with each element of

Hi everybody, I'm having problems with the barchart command in the lattice package. I'm creating barcharts from matrices with with anything from 20 to 71 columns. When I leave the column names alone, that is they are set in the read.table command (and inherited by subsequent commands) the correct number barcharts is created by the "print(barchart(...))" command.

Greetings to the help mailing list. I am in the process of translating a large graphic from xyplot to ggplot2 (13 columns by about rows). I have been unsuccessful trying to understand how to place the following text strings after three days of: * Perusing Wickham's "gg2plot" book; * Searching his site for gg2plot and qplot; * Reviewing the "man pages" for gg2plot; *
