I'm able to do this as follows, but am wondering if anyone knows a simpler way which still avoids explicit loops? > (mystring <- letters[1:5]) [1] "a" "b" "c" "d" "e" > unlist(sapply(mystring[-length(mystring)], + function(x) paste(x,mystring[(grep(x,mystring)+1):length(mystring)],sep=""))) a1 a2 a3

The following code: res <- gsub("(*UCP)\\b(i)\\b", "", "nhgrimelanomaclass", perl = TRUE) results in: Error in gsub(sprintf("(*UCP)\\b(%s)\\b", "i"), "", "nhgrimelanomaclass", : invalid regular expression '(*UCP)\b(i)\b' In addition: Warning message: In gsub(sprintf("(*UCP)\\b(%s)\\b",

Hi STATISTICA has a function called "Two-way joining" (see http://www.statsoft.com/TEXTBOOK/stcluan.html#twotwo) and the reference material states that this is based on the method as published by Hartigan (found this paper: http://www.jstor.org/pss/2284710 through wikipedia). What is the relationship (if any) between the "heatmap" function in R and this technique? Is there an

Hello, All: Try the following: par(bg='transparent') plot(1:3) I get two plots superimposed, one over twice the size it should be, much of it outside the device region. Thanks for all you do to make R such a useful tool. People all over the world live better today, because R helps improve the effectiveness of data analysts. Spencer Graves >

Hi, I wonder if this is expected or I'm doing a wrong thing. pdf() dev.control('enable') library("grid") plot(1) grid.text("A") res = recordPlot() dev.off() cairo_pdf() replayPlot(res) dev.off() *** caught segfault *** address 0x4, cause 'memory not mapped' > sessionInfo() R version 3.3.2 (2016-10-31) Platform: x86_64-apple-darwin13.4.0 (64-bit)

How can I look up the aspect ratio of a plot, so I can use that to correctly adjust the angle of text which is supposed to be parallel to a line in the plot? The following example code works for a 1:1 aspect ratio, but puts the text at the wrong angle if the plot region is short and wide or tall and narrow. I can't find a par() component containing the plot aspect ratio. It will be for

Hi, The `quietly` argument of `require` is documented as follows: quietly: a logical. If ?TRUE?, no message confirming package attaching is printed, and most often, no errors/warnings are printed if package attaching fails. However: > require(foo, quietly=TRUE) Warning message: In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE, :

Hi I am trying to understand what happen with the heatmap.2 code that it used to work (last used in October 2015). I am able to get a heatmap but my colour key doesn't come up and instead I get an error in all my files the used to work. Does anyone has any idea of what could have changed? or how to fix this. Thanks. # Error in seq.default(min.raw, max.raw, by = min(diff(breaks)/100)) :

Dear R users, I have various vector geometry operations to perform on 3-D coordinate data located on multiple (500+) csv files. The code I have written for the calculations works just fine. I have written a 'for' loop to automate the task of extracting the coordinates from the files and perform the analyses. The loop works reasonable well, but if the number of csv files is greater than

I am seeing very strange behaviour in R 3.2.0 patched (r68272) and a new build of R-devel. The sessioninfo() from the former is below. Here's what I see: If I set the locale, and trigger a namespace load, a version comparison gives NA, and I get an error. For example, in a new session started with R --vanilla from the terminal: > Sys.setlocale(locale='en_US.UTF-8');grid::gpar()

For example, subtracting 1:2 from the rows of a two-column matrix: > t(apply(matrix(1:6,ncol=2),MARGIN=1,function(y) y - 1:2)) [,1] [,2] [1,] 0 2 [2,] 1 3 [3,] 2 4 > sweep(matrix(1:6,ncol=2),MARGIN=2,1:2,FUN="-") [,1] [,2] [1,] 0 2 [2,] 1 3 [3,] 2 4 Is there a logic to this difference, or is it just a quirk of the history of these

I am creating a timeline plot, but running into a problem in positions where the values to plot are too close together to print the text without overlap. The simplest way I can think of to solve this (although there may be other ways?) is to create a new numeric vector whose values are as close as possible to the original vector, but spread out to a given minimum difference. For example, take

Hello: I'm having trouble plotting an object of class "ts" that is in a data.frame. I can do it with(data.frame, plot(...)) but not with plot(..., data.frame); see the example below. This work around gets me past this problem. However, I thought the R Core team might want to know about this if they don't already. Thanks for all your work in making

Hello: Clicking "Knit Word" in RStudio 0.99.893 with R 3.3.0, works fine with a vignette with "output: word_document".

Hi This appears to be happening (at least) because cairo_pdf() delays initialising a Cairo surface until BM_NewPage(), rather than initiliasing a Cairo surface in BM_Open(), and replayPlot() triggers some activity (set clip region) on the device BEFORE a new page is started (so the pointer to the Cairo surface is null, so BOOM). Not sure yet whether to blame replayPlot() for not starting

Dear colleagues, I wish to report a problem I encounter when trying to save a graphic to file. When I produce a graphic and try to save it R becomes unresponsive and I must force quit, and then restart R. The problem occurs when I try to overwrite an existing graphic: for example when I made changes to the graphic and want to save the graphic using the original file name. It only happens when I
