Summary: + I am writing an R extension that needs to call dmvnorm more than 10,000 times during a model fitting computation. + My extension uses openmp for parallel execution. + As of R 3.0, it is no longer permitted for threads to call the R interpreter because there is a stack overflow check that always trips because the thread's stack is different from what R is expecting. +

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 have a long label that I would like to split. I found that I could use "strwrap" for simple text. However, this is not working with this label: str = expression(paste("< 20 ?m phytoplankton ","(cells ? ",mL^-1,")")) plot(...., ylab = strwrap(str,20),...) I suspect this is because I'm using "expression" for form my label.

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)))

Well pointed out, Jim! It is infortunate that the documentation for options(digits=...) does not mention that these are *significant digits* and not *decimal places* (which is what Joshua seems to want): "?digits?: controls the number of digits to print when printing numeric values." On the face of it, printing the value "0,517" of 'ccc' looks like printing 4

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

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 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:

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

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 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

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

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 ?

I am sure this is trivial, but I cannot solve it. I make a histogram. There are 5 categories "1",...,"5" and 80 values and the histogram does not evenly space the bars. Bars "1" and "2" have no space between them and the rest are evenly spaced. How can I get all bars evenly spaced? The code: > Q5 [1] "4" "4" "4"

We have a variable that we use to label bars in barplot() and to condition on in xyplot(). Since the labels can be quite long, we use strwrap() on-the-fly to split the strings into several "lines" separated by "\n". With barplot, this works nicely using text(), but with xyplot() it doesn't. In the latter, the labels appear to be "double-spaced" compared to the
