similar to: Text wrap

I would like to wrap a y-axis label onto two lines. My label is an expression containing both text and math symbols. I have looked at plotmath, strsplit(), strwrap(), deparse(), do.call(), substitute() and bquote(). Based on previous posts, I can get plain text to wrap. However, when I try these methods on my label, the exact string is returned, rather than evaluating the math symbols. My

Dear R Community, I am trying to optimize a water quality model that I am using. Based on conversations with others more familiar with what I am doing I plan to implement DEOptim to do this. The water quality model is interfaced through a GUI. I have the input file necessary to alter parameters and run the model as a text file. To do the optimization I have figured out the general procedure

For a variety of displays (mosaicplots, barplots, ...) one often wants to either abbreviate or wrap long labels, particularly when these are made up of several words. In general, it would be nice to have a function, abbreviate.or.wrap <- function(x, maxlength=10, maxlines=2, split=" ") { } that would take a character vector or a list of vectors, x, and try to abbreviate or wrap

Hi: Using this dataframe with quite long column headers, how can I wrap the text so that the columns are narrower. I was trying to use strwrap without success. Thanks reportDF <- structure(list(IDDate = c("3/12/2010", "3/13/2010", "3/14/2010", "3/15/2010"), FirstRunoftheYear = c("33 (119 ? 119)", "n (0 ? 0)", "893 (110 ?

Dear R gurus, I want to wrap labels that are too long for a plot. I have looked at strsplit(), substr(), nchar(), and strwrap(). I think it's some combination but I'm having difficulty trying to figure out the right combo. I think I need to create some new matrix containing the labels already split, though I'm not sure if maybe there is a quick and dirty way to address this

Dear gracious R community, I would like to produce charts of phytoplankton biomass changes through time. Each species has a line, and the biomass varies in mirror form along the line for each species along the X time axis. Here is an example of what I'd like to do: http://www.er.uqam.ca/nobel/r30240/Succession.jpg Any suggestions? Thanks David Bird UQAM, Montreal

I am using barplot, and barplot2 in the gregmisc bundle, in the following way: barplot2(sort(xtabs(expend / 1000 ~ theme)), col = c(mdg7, mdg8, mdg3, mdg1), horiz = T, las = 1, xlab = "$ '000", plot.grid = T) The problem is that the values of 'theme', which is a factor, are in some cases rather long, so that I would like to wrap/split them at a space once they

hi, what I want to do is assigning following code to any object. k<-paste("thank") writeLines(strwrap(k, width = 80,indent = 7,exdent = 6)) To assign the "writeLines" code, I try this a<-writeLines(strwrap(k, width = 80,indent = 7,exdent = 6)) or assign(a,writeLines(strwrap(k, width = 80,indent = 7,exdent = 6))) but it doesn't work. is there any way to solve

Hi everyone. I'm trying to use small letter phi in a graph produced in R. However, the small letter phi does not look as it should. In fact, it looks like this: http://r.789695.n4.nabble.com/file/n3963311/Untitled.png instead of what is here http://en.wikipedia.org/wiki/Phi Here's the code I use: expression(phi [1]) Anyone has an idea?

Hi, This was surprising to me and does not appear to be documented in ?str. After reading ?strwrap, I see that the problem is that "Whitespace ... in the input is destroyed". However, I thought I'd mention it because I'm not sure it is intended behavior for str(). I have a list, and the names of the list have a variable number of characters. > x <- list(A=1:10,

When R prints warnings, they often go "out of the line", it would be better if they where wrapped with writeLines(strwrap ... I tried to do that , changing the function warnings, but it has only effect when called explicitely, not when R prints the warnings unasked. Anyhow, here is the changed warnings: warnings <- function (...) { if (!(n <- length(last.warning)))

Dear R-devs, Scenario: When checking a package via `R CMD check package_tar.ball`, required / suggested packages may be missing. R subsequently returns a list of packages that are missing (delimited by spaces). Example: ``` R CMD check glmSparseNet_0.99.13.tar.gz * using log directory '/home/ubuntu/Bioconductor/glmSparseNet.Rcheck' * using R Under development (unstable) (2018-06-06

Hello! Does anyone know of a handy way to wrap the names.arg text in a barplot? I'm creating a bar plot with rather long labels; I can adjust the margins, but I'd also like to have the text wrap to about 4cm. Thanks! Kyle H.

Hi all, I've got some image plots on which I'd like to include some gene information (in the margins using mtext). Unfortunately, the description is rather long and will need to be wrapped to fit on several lines. From what I know about mtext, it's really only meant for single-line labels, not paragraphs. Here's some sample code of the idea I'm trying to accomplish:

DeaR R-fellows, I got a lot of help from you concerning the generation of heat maps, so I was able to write and work with a script for this purpose at last. Some visitors of our Ecological Station asked about the generation of the graphs and so I decided to write down a small description. Is it adviseable to publish the link to the article in an R-wiki (which?) so I can give back a little to the

Hi All, I have been trying to get to plot my PCA legend outside of the PCA plot, but success still alludes me. Can you guys please advise how I can achieve this. I used locater() to obtain coordinates for below the Comp.1 axis. Using these coordinates the legend disappears. Below is the code for the PCA and legend. Thanks in advance for the help. Regards Tinus r.cols <-

Hi all, I'm writing a function that will automatically generate a report based on answers to a questionnaire. The exact questions and answers to the questionnaire can vary. One of the question types is in a "matrix" format, where the agreement to several statements can be indicated on a scale. I'm planning to plot this on a multilevel barplot, and only labeling each "bar

c <- structure(c(2L, 2L, 1L, 3L, 4L, 2L, 3L, 2L, 3L, 2L, 5L), .Label = c("foo", + "bar", "a really really long variable label mostly here to show the need of word-wrapping text in labels", + "a not so important value", "baz"), class = "factor") plot(c) Is there a way to get the long variable labels to automatically wrap so that all

Hi. Am brand new to R and to mailing lists - have never posted anywhere before, so hope I do this right. Am using R 2.9.1 with lattice graphics (just installed, fully up to date). Am doing trellis xyplot with y (emp=employment), x (yearmo=a time measure) and conditioning variable (indf - factor describing industry) -- i.e., (emp ~ yearmo | indf), where all three variables are in a dataframe. The

Hello, I would like to evaluate the relationship between flows and phytoplankton abundance (or Chlorophyll a concentrations) using a changepoint analysis.? Specifically, I have two study questions: Study Question 1: Are there certain flow thresholds that result in spikes in phytoplankton abundance? Study Question 2: Are the duration of certain flows important for phytoplankton abundance (e.g.,
