Hello all, can rsync sync some directory directlly into a compressed file format.. that way I wouldn't have to compress it myself.... when syncing again it would decompress the file, sync and re-compress :) well, maybe this is a crazy idea... !?!? cheers joao

Hi, I am trying to write a function do cast columns of data frame as factor in a loop, the source is : as.factor.loop <- function(df, cols){ if (!is.null(df) && !is.null(cols) && length(cols) > 0) { for(col in cols) { df[[col]] <- as.factor(df[[col]]) } } } source('D:/ambertuil.r') x <- 1:5 y <- 2:6 df <- data.frame(x=x, y=y)

Hi, It would be great if one of the experts could comment on the difference between Hadley's dotlength and ...length? The fact that someone bothered to implement a new primitive for that when there seems to be a very simple and straightforward R-only solution suggests that there might be some gotchas/pitfalls with the R-only solution. Thanks, H. On 05/03/2018 08:34 AM, Hadley Wickham

the winecfg confused me about DLL overriding. In the 'libraries' tab, if i specified a Dll file name and click 'Add', how does Wine know where to load the native file when need? does it mean i also have to copy the native file into the "c:\windows\system[32]" directory? if so, why i have to bother with the winecfg, why not directlly copy files into the

Hi, In some cases the number of arguments passed as ... must be determined inside a function, without evaluating the arguments themselves. I use the following construct: dotlength <- function(...) length(substitute(expression(...))) - 1L # Usage (returns 3): dotlength(1, 4, something = undefined) How can I define a method for length() which could be called directly on `...`? Or is it an

I am interested in creating multiple (say 1000) time series, from a given stochastic process, of length 250. I want to refer to each realization with its own variable name, of the format say, tsn, where n is the n'th simulation. i.e. ts1, ts2, ts3, ts4, .... , ts1000 The way I am thinking of doing this is placing the following code within another loop, and the 'tsn' assignment should

Hi! It's me again with another --link-dest issue: I am using dirvish (www.dirvish.org) to create daily backup on disk images. dirvish is using rsync with --link-dest pointing to the last good image. This creates images with hardlinks to unmodified files. So far so good. Now I want to create a "current" filetree with hardlinks pointing to the last image. rsync -vaH --delete

This should (hopefully) be a pretty simple task. What I'd like to do is read in a csv file containing means and standard deviations for a large number of 'n' parameters (up to 2000). The list would be in the following format (see attached read.csv): Paramter(1), mean, standard dev., Paramter(2), mean, standard dev., Paramter(3), mean, standard dev., ... Paramter(n), mean, standard

I want to make a glm and then use predict. I have a fairly small sample (4000 cases) and I want to train on 90% and test on 10% but I want to do it in slices so I test on every 10th case and train on the others. Is there some simple way to get these elements? Stephen -- 21/10/2005 [[alternative HTML version deleted]]

In R-3.5.0 you can use ...length(): > f <- function(..., n) ...length() > f(stop("one"), stop("two"), stop("three"), n=7) [1] 3 Prior to that substitute() is the way to go > g <- function(..., n) length(substitute(...())) > g(stop("one"), stop("two"), stop("three"), n=7) [1] 3 R-3.5.0 also has the ...elt(n)

Hi all, This is a design change proposal to make lld's symbol resolution phase mostly-concurrent without changing the existing semantics. The aim of this change is to speed up the linker on multi-core machines. *Background:* Even though many parts of lld are multi-threaded, the symbol resolution phase is single-threaded. In the symbol resolution phase, the linker does the following: - Read

The one difference I see, is the necessity to pass the dots to the function dotlength : dotlength <- function(...) nargs() myfun <- function(..., someArg = 1){ n1 <- ...length() n2 <- dotlength() n3 <- dotlength(...) return(c(n1, n2, n3)) } myfun(stop("A"), stop("B"), someArg = stop("c")) I don't really see immediately how one can
