similar to: automatic "paste" filter to paste only the commands from a transcript on the clipboard

I was trying to create a function with a value computed at creation time, using substitute(), but I got results I don't understand: > this.is.R Error: Object "this.is.R" not found > substitute(this.is.R <- function() X, list(X=!is.null(options("CRAN")[[1]]))) this.is.R <- function() TRUE > # the above expression as printed is what I want for the

Consider the following example: # substitute a with b in the indicated function. Seems to work. > z <- substitute( function()a+1, list(a=quote(b)) ) > z function() b + 1 # z is an object of class call so use eval # to turn it into an object of class expression; however, # when z is evaluated, the variable a returns. > eval(z) function()a+1 Why did a suddenly reappear again

Hi, Is there a way to write a dataframe or table to the clipboard as an image? I want to paste into an email. I use snagit or print screen to do this today but want to know if there is a way to do this through R. For example I know how to write to clipboard for copy and pasting into Excel: > write.table(df,"clipboard",sep="\t" But what's the equivalent for .png or

Hi everyone I've been playing with do.call() but I'm having problems understanding it. I have a list of "n" elements, each one of which is "d" dimensional [actually an n-by-n-by ... by-n array]. Neither n nor d is known in advance. I want to bind the elements together in a higher-dimensional array. Toy example follows with d=n=3. f <-

Does anyone have something like tapply that is extremely fast for matrices when there is a very large number of levels of the grouping variable? I'm referring to, for example, tapply(x, grouping.variable, function.operating.on.submatrix) where x is a matrix and the submatrix is a subset of the rows of x. The grouping variable's length equals the number of rows of x. -- Frank E

I followed the examples of previous posts about R2HTML to practice exporting a data to a clipboard, but the result is not as smooth as I had expected: library(R2HTML) data(iris) HTML(iris, file("clipboard","w"), append=FALSE) I got an error message: > HTML(iris, file("clipboard","w"), append=FALSE) Error in file("clipboard", "w")

I'm trying to create a language structure that is a call to a function with a number of arguments that is only known at run time. I do this by using repeated indices to expand out a call with a single argument. However, when I change one of the arguments, all are changed. I don't see the same behavior when I initially create a call with multiple arguments. Even more strangely,

Howdy, It seems that there's a bit of a problem with Agent accessing the KDE Clipboard through Wine. (Or is it the X Clipboard?) If I start a managed wine Agent session and try to copy from Agent, the copied info shows up in the KDE Clipboard. If I try to paste highlighted text from the console into Agent, it works also. Once. The second (and subsequent tries) don't work. It

I'm consistently seeing R crash with a particular large data set. What's strange is that although the crash seems related to running out of memory, I'm unable to construct a pseudo-random data set of the same size that also causes the crash. Further adding to the strangeness is that the crash only happens if the dataset goes through a save()/load() cycle -- without that, the

Hello, I'm interested in moving text from and to the clipboard that cannot necessarily be represented in the native encoding. So, really, this is about Windows. I can successfully read from the clipboard by specifying the format that corresponds to unicode text. From R >=2.7.0, it seems you should also be able to write unicode text to the Windows clipboard.

This message relates to handling files > 2Gb under Windows. (I use 2Gb as shorthand for 2^31-1 -- the largest integer representable in a signed 32 bit integer.) First issue: truncate() is not able to successfully truncate files at a position > 2Gb. This appears to be due to the use of the Windows function chsize() in file_truncate() in main/connections.c (chsize() takes a long int

Is this a bug? I thought that "clipboard" could always be substituted for a filename when dealing with ASCII files. > data(iris) > save(iris,ascii=TRUE,file="clipboard") Error in file(file, "wb") : `mode' for the clipboard must be `r' or `w' Also this (where gclip is a utility found at unxutils.sourceforge.net that copies its standard input to the

Full_Name: Liam Gretton Version: 2.9.2 OS: openSUSE 11.1 (x86_64) Submission from: (NULL) (143.210.13.77) Reading a large number of rows of delimited data via the clipboard results in a segfault or double free error. I've tested copying from various applications, but gedit will do. This problem exists in the openSUSE-supplied 2.8.1, I've just built 2.9.2 to see if it's still there,

Full_Name: Gabor Grothendieck Version: 1.7.1 OS: Windows 2000 Submission from: (NULL) (207.35.143.81) save(x,ascii=TRUE,file("clipboard")) works but load(file("clipboard")) does not. Even better would be if save(x,ascii=TRUE,"clipboard") and load("clipboard") worked as that would provide consistency with

Is there a way to copy selected text from the X11 Clipboard to Wine? The other way (wine -> x) works fine. Tsch??, Wolfgang -- Wolfgang Becker *** eMail uafr@gmx.de http://www.uni-karlsruhe.de/~Wolfgang.Becker/
