similar to: changed behaviour of 'get' in 2.8.0: request for unchange

I am running R on Ubuntu Heron. I recently updated to R 2.8.0 from the default (2.6) in the Ubuntu heron repository by adding deb http://cran.stat.sfu.ca/bin/linux/ubuntu hardy/ I updated all packages installed in /usr/lib/R/site-library and those in my home directory /home/duncan/R/i486-pc-linux-gnu-library/2.6 without obvious issues. I installed adehabitat and gpclib, which should be good

hello, i have something like: out<-list() for(i in 1:n){ data<-gen(...) #fixed size data out[[i]]<- fun(data) } > object.size(out[[1]]) 6824 In principle 1 GB should allow n = 1024^3/6824 = 157347? i have about 2GB are not taken by other processes. however, I can see the memory shrinking quite rapidly on my system monitor and have to stop the simulation after only n=300. why

Hi Allen and list, See the code below.? I've tried it on R2.13 and R2.8.0 using either heatmap.plus 1.3 or the latest.? All gave the same results.? The problem is in the last line: when I tried to plot two different color bars, the one corresponding to "cm.colors(10)" is not correct (it starts with one black and one red.? Not sure where they're from?) Any ideas? Thanks!

Hi Everybody I use R2.8.0 on Mac OS X. I set up LyX 1.6.1 to use Sweave today. I can compile the test file I found on CRAN ( http://cran.r-project.org/contrib/extra/lyx/) without a problem and the output looks very nice. In the test file the following R code is used. <<myFirstChunkInLyX>>= xObs <- 100; xMean <- 10; xVar <- 9 x <- rnorm(n=xObs, mean=xMean, sd=sqrt(xVar))

Hi, I am trying to aggregate the sum of my test data.frame as follow: testDF <- data.frame(v1 = c("a", "a", "a", "a", "a", "b", "b", "b", "b", "b", "c", "c", "c", "c", "c", "d", "d", "d", "d",

This is hopefully a trivial problem for list subscribers, but I am very new to writing R functions. I wish to call an R function written by myself from another program to fit a model. I need to tell it which of the independent variables are factors. I need to do this in a generic way, so that when the list is passed, R will work through the variables in the data frame and coerce them into being

I'm unable to open an SPSS file over my network. If I copy it to my local C:/ drive I can read it. I saved the command (in a "crib sheet" text file) in order to avoid all the typing, so I'm pretty sure I've done it before. I verified that the file I'm trying to read is OK. This is what happens: > SurveyData <-

When I run the gam function as part of an optimization and do the optimization many times using a loop, I'm finding that memory use increases over time (based on simply monitoring top). Below is some example code that involves varying the penalty parameter in gam, trying to find the value that gives exactly 50 edf for a simple smoothing problem. I thought I would post to the list to see if

Dear developers, I have noticed difference in computation time for the data.frame function between R2.9.0 and R2.8.1. The older release is more efficient: typically, R2.9.0 spends three more time in the data.frame function. Therefore, when many calls of this kind is done inside a function, the additional time spent with R2.9.0 may be several minutes. Looking at the profiling results (see file

Hi List, here I go again. Well I need to save plotted objects as .eps using the postscript() function, well I can do that but all resulting object are perfect squared dimensions (x = y). I need a rectangular output something like x = 2y dimension. Is it possible? The I’m new to R and postscript image format! I’m doing this…

Hello, I need to insert a line after every eigth row (group/suset) which should contains the following: <(an incremented ID),0,1,1,1,1> I have two problems with constructing my code: 1. I am getting NAs in three of the columns and 2) I can not find a way to write the ID (group name) at the beginning of the inserted line. Below the # sign I show one of the ways I tried from a variation

Greetings R-wizards: For historical reasons I have filenames with the character "?" and have successfully used "\u00e2" in its place, with the hoped-for result on all my on-screen plots. However since R2.7.0 I have trouble with savePlot() when the file name includes that character as it does in this example: savePlot(paste("diagnostic ? vs a ", file.label,

The behaviour of the plot function when used with xlim/ylim and the matplot function as in the following simple example changed between R2.6.1 and 2.7.0+ producing ugly plots in the new versions. In case of plot it looks like the pretty function is called with wrong arguments (i.e. range of supplied data rather than values of xlim and ylim): m = matrix(c(-0.033, 0.009, 0.064, 0.050, 0.097,

People who have had "duplicate header extension" and whatever other random index file corruption problems, please see if this fixes anything: http://dovecot.org/list/dovecot-cvs/2006-December/007315.html The change is also in the latest nightly snapshot (http://dovecot.org/ nightly/dovecot-latest.tar.gz). You could in general treat the latest snapshot as "pretty much the

I've been inspired to look at the R source code by some strange timing results that I wrote about on my blog at radfordneal.wordpress.com (see the posts on "Speeding up parentheses..." and "Two surprising things...". I discovered that the strange speed advantage of curly brackets over parentheses is partially explained by an inefficiency in the evalList and

-------- --Multipart_Thu_Apr__8_13:33:51_1999-1 Content-Type: text/plain; charset=US-ASCII Hello guys, I always wondered why smbclient keeps timestamp in `put'ting a file but does not keep it in `get'ting a file. Alternative to keep the time stamp in `get'ting file is to use -Tc option or smbtar script, but they are a bit hairy for interactive use, and it can only dump files with an

Currently, when mget() is used to get the value of a function's argument with no default value and no value in the call it returns the empty name (R_MissingArg). Is that the right thing to do or should it return 'ifnotfound' or give an error? E.g., > a <- (function(x) { y <- "y from function's environment"; mget(c("x","y","z"),

Dear r-devel, I was surprised to see that saveRDS() and readRDS() work quite well with environments, see below: ``` z <- 3 # in global env y <- new.env() y$a <- 1 x <- new.env(parent = y) x$b <- 2 saveRDS(x, "x.RDS") # in a new session x <- readRDS("x.RDS") y <- parent.env(x) x$b #> [1] 2 y$a #> [1] 1 parent.env(y) #> <environment:
