Hi The final line of the example in ?setRefClass induces an error: > ## debugging all objects from class mEdit in method $undo() > mEdit$trace(undo, browser) Error in envRefInferField(x, what, getClass(class(x)), selfEnv) : 'undo' is not a valid field or method name for reference class "refGeneratorSlot" $trace tries to embed the trace in the generator object (instead

Deal all, I want to know if truetype or opentype fonts are available in pdf device (i.e., pdf() or dev.copy2pdf()), and if so, how to do it? Now I can do as followings: 1. convert ttf to afm using ttf2afm, e.g.: $ ttf2afm Impact.ttf > Impact.afm 2. put the afm file in $R_HOME/library/grDevices/afm 3. register a new type1 font: pdfFonts(Impact=Type1Font("Impact",

Hi all, In my continued effort to understand when and what R copies, I've designed a small experiment to try and figure out what goes on when a list gets copied - is it a shallow copy or a deep copy. I believe the following experiment isolates the difference: options(digits = 2) powers <- 4:6 n <- setNames(10 ^ powers, paste0("e", powers)) xs <- lapply(n, seq_len) zs <-

Hi all, I have been using ggplot for a few months and ran into this porblem, I am trying to use ggplot in a for loop and it is not working. if I do the following: data=as.data.frame(cbind(rnorm(10),rnorm(10),rnorm(10))) ############ pp=ggplot(data, aes(x=(1:10), y=data[,1])) pp=pp+geom_line(aes(x=(1:10),y = data[,1]),lty=2) pp=pp+geom_line(aes(x=(1:10),y = data[,2]),lty=2)

I?m in the process of preparing a package for CRAN. The package is called ?exportR? and since it really just consists of one function, I found it natural to call it ?exportR? too. The function returns a function that does the actual job, but it is set up to work in different ways, depending on the arguments given to its creator. In short: library( exportR ) exporter <- exportR( the, arguments

ggplot2 ------------------------------------------------------------ ggplot2 is a plotting system for R, based on the grammar of graphics, which tries to take the good parts of base and lattice graphics and avoid bad parts. It takes care of many of the fiddly details that make plotting a hassle (like drawing legends) as well as providing a powerful model of graphics that makes it easy to produce

Thanks for the reminder about lattice! I did some searching and there's a good example of manipulating the size of subplots using the `position` argument (see pp. 202-203 in the Trellis Users Guide: http://ml.stat.purdue.edu/stat695t/writings/Trellis.User.pdf). This is not within the paneling environment with the headers like in other trellis plots though, so you'll have to do a bit

Hi All, is there a function in R that allows me to work with fractions without transforming them to floats (or whatever) in between? Something that would calculate something like: (1/2 + 1/8) * 1/2 = 5/16 without ever transforming to 0.5 and 0.125? Best, Federico -- Federico C. F. Calboli Department of Epidemiology and Public Health Imperial College, St Mary's Campus Norfolk Place,

I want to find the inverse of an integer k mod p (prime.) Is there a function that can do this for me? I know i could simply write (k^(p-2)) %% p, but i need to do this for large primes (above 100) and this gives the warning message: Warning message: probable complete loss of accuracy in modulus so this method does not work. Any ideas? Thanks, Samuel --

For this kind of control you will probably need to move to base graphics and utilize the `fig` argument in par(), in which case you would want to run the plot() command twice: once with your first outcome and once with your second, changing the par() settings before each one to control the size.

That (the need for base graphics) is false. It certainly **can** be done in base graphics -- see ?layout for a perhaps more straightforward way to do it along the lines you suggest. However both lattice and ggplot are based on grid graphics, which has a similar but slightly more flexible ?grid.layout function which would allow one to size and place subsequent ggplot or lattice graphs in an

Hi Charlie, Thanks. This is helpful. As mentioned in my original question, I want to be able to plot a few such charts on the same page, say a 2 x 2 grid with such a chart for each of 4 different stocks. Using your solution I accomplished this by making a list pLst of your ggplots and then calling cowplot::plot_grid( plotlist=pLst, nrow=2, ncol=2 ) That worked fine. The one issue I have is that
